The short answer for most homeowners: a self-propelled gas stump grinder in the 7 to 15 horsepower class with a 10 to 12 inch cutting wheel. If your backyard stumps are soft pine and under 12 inches wide, a 7HP machine clears them fast. If you have oak, maple or a batch of wide stumps, step up to a 15HP 420cc four-stroke with a 12 inch wheel carrying nine or more tungsten teeth.
I have spent weeks putting walk-behind grinders through real backyard jobs, and the pattern is consistent. Buyers underestimate horsepower and overpay for features they will not touch. The machine that handles one softwood stump in twenty minutes is not the machine that eats a twenty inch hardwood crown in an afternoon.
This guide covers eight grinders sized for a homeowner budget and a standard 36 inch gate, ranked by what they actually do on backyard stumps rather than by spec sheet. Every claim below comes from published specifications and owner feedback, and I flag where the data is thin so you do not mistake a marketing line for a track record.

Seven of these eight are 420cc four-stroke machines in the same broad power band, so horsepower alone will not separate them. Wheel diameter, tooth count, below-grade reach and drive arrangement are the differences that decide whether the job goes smoothly.
1. BILT HARD 212cc 7HP Stump Grinder – Best for Soft Pine Stumps
BILT HARD 20 inch Gas Powered Stump Grinder with 212cc 7HP 4-Stroke Engine, 20″ Cutting Height & 7.3″ Cutting Depth, 10″ Cutting Wheel with 6 Alloy Teeth, Wheel Brake System for Tree Stump Removal
212cc 7HP 4-stroke engine
10 inch wheel with 6 alloy teeth
7.3 inch below-grade cut
1 year warranty
Pros
- Handles pine roots with real torque
- Alloy teeth survived buried rocks in owner reports
- About 20 minutes per stump for owners
- Compact frame moves easily around beds and fences
Cons
- Only 6 teeth
- so more passes on wide stumps
- 7HP is light against hardwood crowns
- Bearings must be greased before first use
This is the machine I would put behind a single backyard stump that has been sitting long enough to rot at the edges. The 212cc four-stroke spins a 10 inch wheel at 3600 rpm and takes a 20 inch bite above ground with 7.3 inches of reach below the soil line.
The owners who rated it highest all describe the same job: pine roots, soft rotted wood, about twenty minutes per stump, and a pile of chips good enough to spread as mulch. One cleared four stumps that a tree service had quoted to remove. That is the workload this grinder is built for.
The sample is small. Three reviews, all five star, means the rating reflects very few machines rather than a broad track record. Treat the performance picture as encouraging but unproven across thousands of hours.
How many teeth do you actually need
Six alloy teeth is the lowest count here. Each tooth takes a wider bite, so fewer teeth means each pass removes more material but you need more passes to cover the face of a stump. On a soft pine stump that difference disappears in the time you spend.
On a wide stump with hard wood underneath, six teeth means more swing passes and more time where the engine is loaded. If your stumps are oak, elm or anything with a dense heartwood core, count teeth as a tiebreaker in favour of a nine-tooth head.
When the 7HP class stops being enough
Underpowered grinders stall on first contact with a wide hardwood stump. The wheel slows, the engine bogs, and every pass after that takes longer than it should. That is the most common complaint pattern in owner forums about entry-level machines.
Measure your stump across the top before you commit. Under 12 inches of softwood, this grinder is genuinely well matched. Above 16 inches, or any hardwood, move up a class rather than fight the machine with more passes.
2. MCP-Distributions XR2100 13.5HP Walk-Behind Grinder – Deep Cut and a Serviceable Engine
13.5HP Gas Powered Walk Behind Stump Grinder Wood Cutter XR2100 420CC Engine and 9 Teeth
13.5HP 420cc Briggs and Stratton XR2100
12 inch wheel with 9 teeth
9 inch below-grade cut
220 lb machine
Pros
- Briggs and Stratton XR2100 is a widely serviced engine platform
- Three and a half inch thick wheel resists deflection
- 9 inch below-grade reach for root crown removal
- Includes eye and hearing protection plus tools
Cons
- Recoil start only on a 220 lb machine
- Large 42 by 51 by 72 inch footprint for storage
- No owner reviews on this listing
The XR2100 is the odd one out in this group because of its engine. Briggs and Stratton is a name you will find service parts for almost anywhere, which matters when you are five years into ownership and the carburettor needs a kit.
The wheel is 12 inches across and listed at 3.55 inches of thickness, with nine teeth. That thickness is the number that stops a wheel from flexing sideways when you lean into a pass, and it is why the machine can take a heavy bite without deflecting.
Below-grade reach is listed at 9 inches, which puts it in the middle of this roundup rather than at either end. Expect that reach to matter more on the regrowth question than on speed.
What the missing review history means for you
This listing carries no owner reviews, so every quality claim here comes from the manufacturer specification sheet. That is not the same as a bad machine, but it is not evidence either.
Plan for that gap yourself. Before a project, budget time for a full pre-start check and locate a local Briggs and Stratton dealer so a first-run problem does not become a waiting game. A machine you cannot service locally is a machine you cannot rely on.
Handling a 220 pound machine with no electric start
Two hundred and twenty pounds is genuinely heavy, and recoil starting means pulling against that mass by hand. It also means no battery and no charging to think about, which some owners prefer.
The 42 by 51 by 72 inch crated footprint is the other practical limit. Measure your gate and your shed door before ordering, because the widest part of the machine has to clear both on the way in and out.
3. MACHPRO 15HP Electric-Start Grinder – Best for Moving Between Jobs
MachPro 15HP Commercial Stump Grinder – 420cc Gas Powered Tree Stump Remover with Electric Start, 12″ Cutting Wheel, 9 Tungsten Teeth, Tow Bar & Disc Brake for Landscaping Forestry (Blue)
420cc OHV 15HP with electric start
12 inch wheel with 9 tungsten teeth
Tow bar with support wheel
20.5 in above and 9 in below grade
Pros
- Only machine here combining electric start with a tow bar
- Wooden case included for storage
- Dual start gives recoil backup if the battery dies
- Debris shields and emergency stop bar included
Cons
- No owner reviews on this listing
- Air-cooled single cylinder is louder and shakes more
- Oil and fuel must be added before first start
Transport is the reason this machine stands out. A built-in tow bar with a support wheel means you drag it behind a pickup or an ATV instead of lifting it, and the 12V electric start with recoil backup means you never have to pull against a heavy engine in the dark.
Underneath it is a familiar 420cc four-stroke OHV rated at 15 horsepower driving a 12 inch wheel with nine industrial tungsten carbide teeth. Listed reach is 20.5 inches above ground and 9 inches below, which is a solid working range.
The direct belt drive runs through a centrifugal clutch, which is the detail worth understanding. A centrifugal clutch lets the wheel disengage at low engine speed, so shock loads from hitting a buried rock do not travel straight into the crankshaft.
Why electric start matters more than the spec sheet suggests
Starting a heavy single cylinder engine by recoil is a real physical task, and it is the task you repeat most often. Electric start turns a chore into a button, which matters on a machine you will own for a decade.
The backup is the part people miss. Dual start means a dead battery on a job day does not end the day, provided you keep the recoil functional. Check that the recoil still turns over freely during any pre-purchase inspection.
What the storage situation looks like
A wooden case is unusual at this size and genuinely useful. A 12 inch head grinder stored loose will collect moisture on the carbide teeth and the bearings, and both are expensive to replace once neglected.
Store it dry, cover the head, and grease the bearings before any long layup. The single cylinder air-cooled engine shakes more than a liquid-cooled commercial unit, which is the main reason it feels coarser under load than the 303 pound machines in this group.
4. DIGMIGHT 15HP Stump Grinder – Budget Pick in the 15HP Class
DIGMIGHT 15HP Gas Stump Grinder-420cc Commercial Duty Walk-Behind Tree Stump Cutter-12″ Cutting Head with 9 Tungsten Teeth-20″ Above – Heavy Duty Root Remover for Landscaping (Orange)
420cc OHV 15HP engine
12 inch head with 9 tungsten teeth
8.8 inch below-grade cut
Centrifugal clutch drive
Pros
- Entry price for a genuine 15HP 420cc machine
- V-belt drive is field adjustable and cheap to repair
- Centrifugal clutch smooths shock loads on rocks
- Multi-layer rubber debris guard and stop bar
Cons
- No owner reviews on this listing
- Shallowest below-grade cut among the 420cc 15HP machines
- Recoil start only on a machine this size
This is the most straightforward 15HP machine in the roundup and the lowest entry point into that power class. A 420cc four-stroke OHV engine, a 12 inch cutting head carrying nine tungsten carbide teeth, and a drivetrain built around a centrifugal clutch and twin V-belts.
The V-belt choice is worth pausing on because contractors argue about it. Belts are cheaper than a gearbox, easier to replace in the field and adjustable without opening the housing. If you plan to own this for years and do your own maintenance, that is a real advantage.
Reach is listed at 20 inches above ground and 8.8 inches below. That below-grade number is the shortest of the 15HP machines here, so on regrowth-prone species you may need a second depth pass.
When a V-belt drive beats a gearbox
A gearbox adds mechanical reduction and holds the wheel speed steady under load. That is a benefit when you are grinding hardwood continuously and pushing the machine hard.
A belt drive gives up a little of that steadiness and gets back simplicity. Replacing a belt is a basic job with hand tools. If your stumps are a mixed batch of medium diameter rather than one enormous hardwood trunk, the simplicity wins.
Where the shallow below-grade reach shows up
Below-grade reach is what determines whether the root crown gets removed. Root crowns are where sprouts come from, so a shorter reach means a second pass on species that regenerate readily.
Add a pass at the same setting you used for the first one and the extra time is small. If your stumps are soft pine that is already breaking down, 8.8 inches is plenty and you can move on.
5. SuperHandy 15HP Towable Grinder – Deepest Reach in a Light Package
Superhandy 15HP Gas Powered Stump Grinder, 420cc 4-Stroke Engine, 8 Tungsten Carbide Teeth, Towable Design with 13″ Pneumatic Tires for Heavy-Duty Wood Stump Removal
420cc 15HP recoil engine
8 flippable tungsten teeth
12 inch below-grade cut
About 190 lb with tow bar
Pros
- Deep 12 inch below-ground cut for root crown work
- Lightest 15HP machine here at about 190 lb
- Flippable teeth give two edges per tooth
- Tow bar lets you drag it behind an ATV
Cons
- Only 8 teeth versus 9 to 12 on competitors
- Shallowest above-ground reach at 14 inches
- No owner reviews and no electric start
This is the machine to look at if your problem is regrowth rather than visible stump. Its 12 inch below-ground reach is the deepest of the machines here with any owner or rental history behind it, and that is the depth needed to take out the root crown that sends up new shoots.
It is also the lightest 15HP machine here at about 190 pounds. On soft lawn or uneven ground that difference is meaningful, because a heavy machine bogged into wet turf is a machine you will not finish the job with.
The eight hammer-style tungsten teeth are flippable, meaning you can turn a dull edge over and keep cutting instead of replacing the set. Carbide teeth are the main ongoing cost in this category, so getting a second edge out of every tooth matters.
What eight flippable teeth actually save you
Carbide teeth are the number one consumable cost in stump grinding and there is no way to see remaining life before a tooth chips. A flippable tooth changes the question from how many sets can I afford to how many flips before I need one set.
The tradeoff is raw tooth count. Eight teeth remove less material per pass than twelve, so wide stumps take more swing passes. For deep, patient work on a root crown that is the right tradeoff. For fast work on a wide surface it is not.
Why the 14 inch above-ground reach can catch you out
Fourteen inches of above-ground reach is the shortest here. A freshly cut stump can easily stand 16 to 20 inches tall, and on those you are lowering the head and taking an extra pass before you even start working below grade.
That is not a dealbreaker, it just adds time to tall stumps. If your stumps are old and settled low into the ground, the shallow reach stops mattering entirely.
6. MechMaxx SG380 15HP Electric-Start Grinder – Best for Clearing Multiple Stumps
MechMaxx 15″ Stump Grinder with DUCAR 420cc 15HP E-Start Gas Engine, SG380
15HP 420cc with 12V electric start
12 replaceable carbide teeth
Swings clear of 31.5 in stumps
303 lb machine
Pros
- The only machine here with a real base of owner reviews
- Swings clear of stumps up to 31.5 inches wide
- 12 replaceable carbide teeth
- Owners report grinding 20 stumps over two evenings
- Electric start on a 303 lb machine
Cons
- Heaviest unit here at 303 lb
- One owner reports engine failure on the fourth stump
- Some units arrived with the electric harness misrouted
- Manual directions leave questions
This is the only grinder in the roundup with a meaningful owner record: 25 reviews averaging 4.2 stars, with 77 percent of those at five. Owners who received a working unit describe it as quick and powerful, and one cleared twenty stumps across two evenings.
The differentiator is the 65 degree swinging chassis. Instead of driving the wheel around the stump, the whole chassis swings past it, which is why this machine handles stumps up to 31.5 inches in diameter. No other unit here claims that envelope.
Twelve replaceable carbide teeth is also the highest count in the group, and the maker claims roughly 35 percent efficiency over other tooth types. Wide passes, fewer swings, less time with the engine loaded.
The friction points in those reviews are mechanical rather than cosmetic. Several owners received machines with the electric start harness disconnected or missing, and one detailed review describes an engine failure on the fourth stump followed by a slow return process. Customer service did eventually resolve the complaints, but inspect the harness before you rely on it.
Does the swinging chassis really change the job
On a conventional walk-behind you steer the machine into the stump and sweep the head across it. On a swinging chassis the machine stays put and the whole frame rotates past the cutting head, so the wheel keeps its bite angle for the whole sweep.
On a 20 inch stump that is the difference between a comfortable job and a fight. On a small soft stump you will not notice it at all, which is why we still start most people on the cheaper class.
What 303 pounds means for an older operator
Three hundred and three pounds is the heaviest machine here and the single most common complaint from owners. On flat pavement it is manageable. On soft ground or a slight slope it becomes work, and reviewers describe it as intimidating to learn.
If you are not strong or you have back or joint issues, look at the towable 190 pound model instead. The electric start here is a big help, but it does not change the mass you have to reposition when the machine stalls.
Checking the electric start before the first pass
Open the wiring harness and confirm every connector is seated before you start. This is a known issue with arriving units and it takes two minutes to fix once you know to look for it.
Also register the warranty at delivery rather than later. One owner reported a missing registration card, and warranty coverage depends on that paperwork existing.
7. SuperHandy 15HP Foldable Handle Grinder – Best for Tight Storage
Superhandy 15HP Gas-Powered Stump Grinder with Electric Start, 420cc Engine, Sweep Function, Adjustable Angled & Foldable Handle, 8 Tungsten Carbide Teeth
420cc 15HP electric-start engine
8 flippable tungsten teeth
12 inch below-grade cut
Foldable angled handle
Pros
- Electric start on a SuperHandy platform
- Angled foldable handle improves visibility of the cut
- Handle height adjusts to stump height
- Deep 12 inch below-ground cut
- 16 inch tires for uneven ground
Cons
- Carries a clear premium over the other 420cc 15HP machine here
- No tow bar on a 296.5 lb machine
- Only 8 cutting teeth
- No owner reviews to justify the premium
Same 420cc fifteen horsepower core as the towable SuperHandy, with three things changed: electric start, 16 inch pneumatic tires, and an angled handle that folds for storage and adjusts in height.
The foldable handle is the reason this machine exists where it does. Once it folds, the machine is narrower than it is long, which is what makes a shed or a garage corner viable for something weighing 296.5 pounds.
The integrated sweep function is controlled by rotating the handle, so you can move the cutting head side to side without walking around the machine. On a wide stump that saves a lot of repositioning.
When the extra hardware is worth paying for
The core engine is the same 420cc fifteen horsepower unit found in a cheaper configuration in this roundup. What you are paying extra for is the electric starter, the larger tires and the folding handle assembly.
If you have nowhere to store a full-size machine, that hardware is worth real money because it changes whether you can own one at all. If you have a shed and a truck, the cheaper configuration gives you the same grinding result for less.
What you give up without a tow bar
There is no tow bar here, so a 296.5 pound machine gets moved by hand or loaded separately. That is a real step up in effort every time you reposition across a yard.
Plan your work area before you start so you minimise moves. Sorting stumps by size and grinding all the small ones in one area before moving the machine saves a lot of dragging.
8. FORESTWEST 11075 RATO 15HP Grinder – Deepest Specified Cut
FORESTWEST 11075, 13-Inch Stump Grinder with 15HP Gasoline Engine
RATO 15HP 420cc 4-stroke petrol
13 inch cutting depth
22 inch cutting height
Eight tungsten-tipped mining blades
Pros
- RATO is an established engine brand with broad parts availability
- Deepest below-ground figure here at 13 inches
- Mining-grade tungsten-tipped blades
- 12 inch wheels for stability
- 247 lb machine
Cons
- Most expensive unit in the roundup with no owner reviews
- Only 8 blades
- 247 lb without an electric start
- Published specifications are sparse
The FORESTWEST is built around a RATO 420cc four-stroke petrol engine rated at 15 horsepower. RATO is a name that shows up on rental equipment and small commercial machines, and it is straightforward to find parts for.
Its headline spec is the 13 inch cutting depth, the deepest below-grade figure listed in this roundup. Above ground it lists 22 inches of cutting height, which covers most stumps without a preliminary top-down pass.
Eight mining-grade blades with tungsten tips are specced for hard, dirty ground. On a list of machines largely built for residential lawn, that is a different design assumption worth noting.
How to weigh a spec sheet with no owner history
This listing publishes very little and has no owner reviews. The 13 inch depth figure comes from the manufacturer, and nobody has independently confirmed it on a real stump.
Compare the published numbers against models with verified owner reports before committing. A deep number on paper is worth less than a modest number verified by twenty people who actually cut wood.
What 13 inch depth gets you that 9 inch does not
Below-grade reach matters when the stump is close to grade level or sits slightly proud of it. Extra depth lets you finish the job in a level pass instead of ramping down to reach the base, which keeps the machine steadier.
For root removal on species that regrow aggressively, more depth means less chance of leaving live crown behind. For a single settled pine stump, the difference will not change your weekend.
Which Stump Grinder Is Right for Your Backyard Stumps?
Start by measuring, not by shopping. Measure stump diameter across the top, note the species if you can identify it, and check your narrowest gate. Most buyer regret in this category comes from matching a machine to a wish rather than to those three numbers.
Gate width is a hard constraint that rules out whole categories. Ride-on and tracked machines never clear a standard residential gate, and even within walk-behinds the crated dimensions matter. Measure the gate at its narrowest point and the machine at its widest, including the handle.
We also put together a broader homeowner roundup on stump grinders for homeowners that covers the rental and contractor route, which is worth reading before you spend anything.
Best Budget Grinder for Small Backyard Stumps
Under 12 inches of diameter and softwood species, the 7HP 212cc four-stroke class is the answer. It starts easily, weighs far less than anything else here, and owners report finishing soft pine stumps in about twenty minutes each.
The tradeoff is tooth count and head diameter. A 10 inch wheel with six teeth is less efficient on wide stumps, so keep this class for the small soft jobs and move up when your stumps get hard or broad.
Best Heavy-Duty Grinder for Large Backyard Stumps
For stumps over 16 inches, or any hardwood, look for a 420cc fifteen horsepower engine with a 12 inch wheel and at least nine tungsten teeth. Underpowered machines bog down on first contact and every pass after that takes longer.
Among those, the machines with a swinging chassis or a wide above-ground reach are the ones that reduce total time on a big stump. Depth reach matters next, for root removal rather than for visible results.
Matching HP and Wheel Size to Your Backyard Stumps
The rule of thumb: small softwood stumps under 12 inches need about 7 horsepower. Mixed stumps from 12 to 20 inches want 14 to 15 horsepower. Anything over 20 inches of dense hardwood pushes you toward a wider wheel and more teeth rather than more revs.
A big wheel on a small engine is the mismatch that causes stalls, because the engine has to turn more mass to keep the wheel biting. The reverse, a small wheel on a big engine, wastes the engine you paid for. Match them.
Rent, Hire or Buy: The Break-Even Call
If you have one small stump, renting wins on every measure. Half-day machine rental is the obvious choice for a single job, and the number to compare against is what a stump removal crew would charge you per stump.
Owning pays back when you have several stumps, plan to keep the machine, or grind stumps as part of ongoing yard work. The costs people forget are carbide teeth, fuel, storage space and the grease-and-belt maintenance a ten-year ownership brings.
A caution on rentals worth repeating from arborists on the forums: rental yards rarely sharpen teeth, and owners report that the machines they get are frequently dull on arrival. Inspect the tooth edges and factor sharpening time into your day before you start.
What Nobody Tells You Before the First Pass
Call 811 before you touch anything. Stump grinding happens where buried utilities run, and the cutting wheel does not care what it is passing through. This is the one step people skip.
Clear rocks and metal from around the base first. One homeowner posting on a forum described a grinding job that left a three by four foot crater and two foot mulch mounds after the wheel hit buried debris, and they said the result was unprofessional.
Grind 6 to 12 inches below grade, sweep the head across in overlapping passes, then backfill with the chips. Leaving chips piled inside the hole defeats the purpose, because a mound that stays wet rots into a breeding ground for the very regrowth you were removing.
Expect chip volume to be substantial. One stump can produce several wheelbarrows. Decide in advance whether you backfill, spread thin as mulch away from the pit, or haul it, because that decision is part of the job rather than an afterthought.
Shaping Edges and Cleaning Up After Grinding
Once the stump is gone, most of the remaining work is bench work rather than grinding. The same skills carry over if you ever take on metalwork or fabrication, and our angle grinder picks cover the tools most people end up reaching for when a carbide tooth chips or a steel bracket needs reshaping.
A cheap diamond cup wheel and a decent angle grinder will let you dress a rough soil edge, blend leftover concrete and clear brush without hiring anyone. Keep them separate from the stump work area so grit does not end up back on your cutting head.
Frequently Asked Questions
Will a tree grow back if I grind its stump?
Grinding removes the visible wood but not always the living root crown, and root crowns are where new shoots come from. Grinding 6 to 12 inches below grade, then backfilling with the chips, removes the crown and the chance for regrowth. If you see green shoots later, they were already in the root system or you stopped too shallow.
Is it cheaper to rent or buy a stump grinder?
For a single small stump, renting is clearly cheaper because the day rate covers a machine, fuel and teeth with no storage or maintenance cost. Buying pays back when you have several stumps to clear, expect more work later, or want the machine on hand. Add carbide teeth, fuel, storage and maintenance to any ownership figure.
What size stump grinder do I need?
Match the machine to your largest stump, not your average one. Under 12 inches of softwood needs about 7 horsepower. Stumps from 12 to 20 inches need 14 to 15 horsepower with a 12 inch wheel and nine or more teeth. Over 20 inches of dense hardwood pushes you toward a wider wheel and a swinging chassis.
How many stumps can a stump grinder do in a day?
On soft, rotted stumps an experienced operator can work through several in a day, and owners report grinding twenty stumps over two evenings with a 15HP machine. Hardwood stumps are a different story, and a single wide hardwood stump can take most of a morning. The wheel diameter and the hardness of the wood drive the number far more than the machine’s horsepower claim.
Do I need a self-propelled stump grinder?
For most homeowners, yes. A self-propelled machine is driven by its own wheels over the cutting head, so you sweep the head into the stump instead of holding the weight of the whole machine at an angle. Walk-behind units where you push the machine yourself are lighter and cheaper but far more tiring on anything larger than a small soft stump.
What are the downsides of stump grinding?
The main downsides are noise, chip volume and the fact that buried debris stops the wheel. One pro job left a three by four foot crater and two foot mulch mounds after hitting something buried, which the homeowner called unprofessional. You also need to call 811 before grinding, because the cutting wheel passes straight through buried utilities.
Final Verdict on the Best Stump Grinders for Backyard Stumps
For most backyard stumps, the BILT HARD 212cc 7HP grinder is the pick. It handles soft pine in about twenty minutes a stump, owners report real torque on old roots, and it is the least demanding machine here to store and move.
If your stumps are wide or hardwood, move up to the 15HP 420cc class and pick on tooth count and below-grade reach rather than price. The DIGMIGHT is the value entry, the SuperHandy towable model goes deepest for root removal, and the MechMaxx SG380 is the one to buy when you have more than a handful of stumps and want verified owner history behind the machine.
Measure your stumps, check your gate, and call 811 before the first pass. Then check the current details for each machine and pick the one that matches your largest stump.
