Key takeaways
- Engine: 420cc 4-stroke gasoline, 15 HP class — the standard power plant for homeowner and light commercial walk-behinds
- Cutting height: 24 in (head travel above grade)
- Cutting depth: 10 in below grade
- Format: walk-behind, wheeled chassis, lever controls
- Fuel class: gasoline; a 420cc single under grinding load typically burns in the 0.7–1.2 gal/hr range, so plan on roughly 2–4 hours per gallon-and-a-half tank
- Consumables: carbide-tipped cutter teeth on a bolt-on wheel
For a homeowner who wants to buy once and grind two to six stumps up to roughly 20 in across, the best overall pick is the BILT HARD 24 in Gas-Powered Stump Grinder: a 420cc, 15 HP walk-behind with a listed 24 in cutting height and 10 in cutting depth, which is the same working class as the light commercial machines you would otherwise rent by the half-day. If your stumps are under about 6 in, or you mainly need to shave root flares and surface roots flush, the best budget route is the LithiCraft 3-Piece Angle Grinder Wood Carving Disc Set, which turns an angle grinder you already own into a surface-cutting tool for a small fraction of the cost. If you already own a compact tractor, the best premium pick is the MechMaxx SG24PRO PTO Stump Grinder — it borrows the tractor’s engine, so you buy an implement instead of a second engine to fuel, store and maintain. Everyone else should read the cutting-wheel arithmetic and the decision matrix below first, because stump diameter, access width and grinding depth decide the right machine long before horsepower does.
Top 3 Picks
Best overall: BILT HARD 24 in Gas-Powered Stump Grinder
The 420cc, 15 HP engine and 10 in cutting depth put this machine in the class that removes a mid-size hardwood stump to turf grade in about an hour, and the 24 in cutting height lets you work a tall cut stump down from the top instead of only at ground level. It suits the homeowner with two to six stumps, level-to-moderate access, and no tractor. Buy it if you want one purchase that covers both the first stump and the fifth.
Best budget: LithiCraft 3-Piece Angle Grinder Wood Carving Disc Set
A three-piece set of 115 mm (4-1/2 in) tungsten carbide shaping discs with a 22 mm bore that fits the arbor most 4-1/2 in angle grinders use. It is a surface and root-flare tool, not a stump remover — but for stumps under 6 in, exposed root plates, and cleaning up grindings around a hole, it costs less than a single day’s rental and stores in a drawer.
Best premium: MechMaxx SG24PRO PTO Stump Grinder
A heavy-duty, tractor-mounted grinder driven by the tractor’s PTO at 540 RPM, with a three-point hitch mount and a swing geometry built for larger stumps than any walk-behind in this list. It is the cheapest cost-per-stump option if you already run a 20–30 PTO HP tractor, and the most expensive mistake if you do not.

How We Chose
This list is built from published product listings, manufacturer spec sheets and the established physics of how stump-removal tools cut, not from operating the machines. Three filters decided what made the cut. First, category fit: a walk-behind gas grinder, a PTO implement, a replacement tooth kit and an angle-grinder disc solve four genuinely different problems, so each was judged against its own category rather than against horsepower alone. Second, the numbers that actually predict performance — engine displacement and class, cutting depth below grade, cutting height, wheel and disc diameter, bore size, tooth count and tooth profile — were checked for internal consistency and for whether they matched a real, common machine configuration. Third, upgrade path and consumables: a machine with widely available 500-series-compatible teeth is cheaper to own over five years than one with a proprietary tooth, and a disc set is only useful if its bore and diameter match the grinder already in the reader’s garage. Where a listing did not state an exact figure, we described the spec class instead of guessing a number.
1. BILT HARD 24 in Gas-Powered Stump Grinder – Best for One-and-Done Homeowner Stump Removal
This is the machine for the homeowner who has looked at a rental counter, done the math on a half-day minimum plus a trailer, and decided to own instead. The BILT HARD is a walk-behind, gasoline-powered stump grinder built around a 420cc 4-stroke engine in the 15 HP class, with a listed 24 in cutting height and 10 in cutting depth. That combination matters more than the headline horsepower: the 10 in depth figure is what lets you grind below turf grade so you can rake, topsoil and seed over the hole, and the 24 in cutting height means the wheel head raises high enough to work down a tall cut stump from the top rather than only attacking it at ground level.
Key specs
- Engine: 420cc 4-stroke gasoline, 15 HP class — the standard power plant for homeowner and light commercial walk-behinds
- Cutting height: 24 in (head travel above grade)
- Cutting depth: 10 in below grade
- Format: walk-behind, wheeled chassis, lever controls
- Fuel class: gasoline; a 420cc single under grinding load typically burns in the 0.7–1.2 gal/hr range, so plan on roughly 2–4 hours per gallon-and-a-half tank
- Consumables: carbide-tipped cutter teeth on a bolt-on wheel
Strengths
The 15 HP / 420cc class is the sweet spot for private property because it has enough torque to keep a carbide wheel turning in dry oak without stalling, yet it remains a machine one person can move on a hand truck or roll through a garden gate. At the material-removal rates typical of this class — roughly 20–45 in³ per minute of actual cutting in hardwood — a 14 in stump ground 8 in deep is about an hour of work including repositioning, which is the difference between a Saturday morning and a lost weekend.
The 24 in cutting height is an underrated spec. Many stumps get cut 12–24 in above grade by whoever felled the tree, and a machine that cannot raise its head above that cut has to be fed into the side of the stump, which is slower and puts more side load on the wheel. Being able to come down from the top is both faster and easier on the teeth.
It also sits in the most widely supported consumable ecosystem in the category. Teeth, bolts and wheels for 15 HP-class walk-behinds are commodity items, which means five-year ownership cost is dominated by fuel and teeth, not by hunting for a proprietary part.
Pros
- 15 HP / 420cc class has enough torque for hardwood stumps without stalling
- 10 in cutting depth clears turf-grade removal with headroom to spare
- 24 in cutting height handles tall, badly cut stumps from above
- Walk-behind format fits through most residential gates and needs no tractor
- Common tooth and bolt sizes keep long-term running costs predictable
Cons
- Gasoline engine means fuel storage, oil changes, air filters and seasonal starting rituals
- At roughly the 200–350 lb class, it is not a one-hand carry and not suitable for steep slopes
- Large stumps over about 24 in need multiple setups around the perimeter regardless of power
- Significantly more expensive than renting for a single stump, or than an angle-grinder disc for a 5 in stump
How it compares
Against the SuperHandy 15 HP, the BILT HARD leans on cutting geometry — the 24 in height and 10 in depth figures — while the SuperHandy emphasizes a towable chassis and a listed 8 tungsten carbide teeth. If you move between two properties, towing matters more than head travel. Against the MechMaxx with Support Leg, both use a 420cc 15 HP-class engine, but the MechMaxx is built around a support-leg stance for standalone stability, while the BILT HARD is the more conventional walk-behind layout. Pick the BILT HARD if your stumps are tall-cut and your property is flat to gently sloped; pick a towable if the machine has to travel.
2. LithiCraft 3-Piece Angle Grinder Wood Carving Disc Set – Best Budget Pick for Small Stumps and Root Flares
This is the honest small-stump tool. Three 115 mm (4-1/2 in) tungsten carbide wood-shaping discs with a 22 mm bore, sized for the arbor that most North American 4-1/2 in angle grinders use. It is not a stump grinder in the walk-behind sense and it will not remove a 16 in oak stump in any reasonable time — but it will take a 4 in volunteer maple down below grade, shave a root flare flush so a mower stops catching it, cut through surface roots in a planting bed, and clean up the frayed edges around a hole after a real grinder has been through.
Key specs
- Disc diameter: 115 mm / 4-1/2 in
- Bore: 22 mm (matches the 22.23 mm / 7/8 in arbor standard on most 4-1/2 in grinders — verify against your spindle before mounting)
- Cutting material: tungsten carbide
- Set contents: 3 pieces
- Typical grinder pairing: 900–1,400 W, 10,000–11,000 RPM no-load class
Strengths
The economics are the whole point. A set like this costs a small fraction of even a half-day rental, and it uses a power tool many homeowners already own. For the specific jobs where it works — a stump small enough that a mattock and an afternoon would also do it, a root flare that keeps hitting the mower deck, roots running under a patio edge — it is faster and less destructive than digging.
Carbide shaping discs also leave a cleaner surface than you would expect. Because the cutting action is a scraping/planing motion rather than a chisel bite, the finished stump top can be brought close to flush with the soil line, which is exactly what you want when the goal is “stop the mower from bottoming out,” not “replant a tree here.”
Three discs in one set also means you can dedicate one to soil-contaminated work. Once a disc has chewed through gritty root material, its edge life drops; having a spare keeps you cutting instead of stopping to order another.
Pros
- Lowest entry cost of anything in this list by a wide margin
- Fits tools most homeowners already own
- Ideal for root flares, surface roots and stumps under about 6 in
- Fits through a gate, onto a slope or into a bed no wheeled machine can reach
- Three discs let you separate clean-wood and dirty-root work
Cons
- Material removal rate is roughly 1–3 in³ per minute in hardwood — an order of magnitude below a gas machine
- Not realistic for full removal of stumps larger than about 6 in
- Requires removing or modifying the grinder guard to fit, which raises kickback and debris risk
- Bore and spindle compatibility must be checked; a mismatched arbor is a non-starter
How it compares
Against the DTTXYSD 5-Piece Set, the LithiCraft is a tighter, purpose-built three-disc kit while the DTTXYSD spreads five pieces across 4–4.5 in grinders in carbon steel. Carbon steel is generally easier to sharpen but holds an edge for less time in gritty soil than carbide, so the LithiCraft set is the better pick for repeated root work and the DTTXYSD is the better pick if you want maximum variety for occasional shaping. Against the Honoson 22-tooth chain disc, the LithiCraft is the gentler, more controllable tool: a 22-tooth chain disc removes material much faster but bites harder and kicks back more aggressively, so the carbide shaping discs are the safer starting point.
3. MechMaxx SG24PRO PTO Stump Grinder – Best Premium Pick for Tractor Owners
If there is a 20–30 PTO HP tractor in your shed, this is the most efficient way to own stump-removal capability. The SG24PRO is a heavy-duty, PTO-powered stump and root grinder that mounts on the tractor’s three-point hitch and runs off the 540 RPM PTO, which means the engine, fuel system, air filter and battery you are paying to maintain are ones you already own. You buy an implement, not a second machine.
Key specs
- Drive: tractor PTO, 540 RPM standard
- Mount: three-point hitch, category 1 class
- Build: heavy-duty stump and root grinding head
- Finish: orange (high-visibility, useful when working near fences and property lines)
- Tractor requirement: typically a compact utility tractor in the 20–30 PTO HP range for full-depth work; more PTO HP cuts faster and stalls less
- Consumables: carbide-tipped cutter teeth, standard bolt-on replacement
Strengths
The power budget is the argument. A 25 HP tractor delivers roughly 18–22 HP at the PTO, and a PTO grinder converts that through a heavy flywheel-and-wheel assembly rather than through a small single-cylinder engine’s clutch. The practical result is a higher material-removal rate per pass — commonly in the 35–70 in³ per minute range for a compact tractor setup in hardwood — plus the ability to reposition using the tractor’s hydraulics instead of your shoulders.
That hydraulic repositioning is the difference between a 25-minute stump and a 90-minute stump. On a walk-behind, every move around the perimeter is a manual shove of a 250 lb machine. On a three-point implement, you lift, swing and set down with the tractor’s own controls, and you can work a 24–36 in stump from two or three positions without ever getting off the seat.
Storage and maintenance also favor the PTO route. One engine to winterize, one fuel can, one service schedule. The implement itself is largely a gearbox, a shaft and a wheel — few failure points, and the ones that exist are the teeth.
Pros
- Lowest cost-per-stump if you already own a suitable tractor
- 18–22 PTO HP from a compact tractor outperforms any walk-behind in this list
- Hydraulic repositioning removes the hardest physical work
- No second engine to fuel, service or store
- Handles stumps in the 24–36 in range that force multiple setups on a walk-behind
Cons
- Completely useless without a tractor — the single biggest disqualifier
- Tractor plus implement cannot reach the tight corners, narrow gates or steep slopes an angle grinder disc can
- Requires PTO shaft safety practices, including shielding and a slip clutch or shear bolt
- High upfront cost if you buy the tractor and implement together for this one job
How it compares
Against the MechMaxx 420cc gas walk-behind with support leg, the SG24PRO is faster and cheaper per stump — but only if the tractor exists. Without one, the gas walk-behind is the only one of the two that actually removes a stump. Against the SuperHandy 15 HP towable, the PTO unit wins on cutting rate and loses on independence: the SuperHandy can be towed behind a garden tractor or an ATV and operated on its own, which the SG24PRO can never do. Tractor owners should buy the SG24PRO; everyone else should not.
4. Chumia 3-Pack Stump Grinder Teeth Replacement Kit – Best for Refreshing a Dull Cutter Wheel
A blunt stump grinder is not a slow stump grinder — it is a machine that heats the wood, throws dust instead of chips, and takes two to three times as long per inch of depth. This kit is a carbide-tipped replacement tooth set with mounting bolts, sold in a three-pack, aimed at exactly that moment: the point where your chips turn to powder and the engine note stops dropping when the wheel bites. It is a maintenance part, and it belongs in the same category as a spare chain for a chainsaw.
Key specs
- Type: carbide-tipped cutter teeth
- Included: teeth plus mounting bolts
- Quantity: 3-pack
- Compatibility: verify tooth shank size and bolt pattern against your cutter wheel before ordering — the profile must match the pocket
- Wear point: the carbide tip; replace or rotate when the tip is worn past roughly 1/8 in
Strengths
Bolts included is a bigger deal than it sounds. Stump grinder teeth are held by bolts that live in an abrasive environment, and the bolt heads round off, seize or get lost in the chips. A kit that ships teeth and hardware together means you can do a full replacement in one session instead of stopping halfway to hunt for a matching fastener.
Carbide tips are the right material choice for this job. The cutting environment is wood plus embedded grit plus occasional small rocks, which is a wear regime that destroys high-carbon steel edges quickly. Carbide holds up far longer, and the practical cost calculation is that a set of carbide teeth usually outlasts several sets of steel equivalents even though it costs more up front.
A three-pack also maps neatly onto a rotation schedule. Rotating teeth a quarter turn when they dull extends their life, and having three spares on the shelf means you can rotate the working set and replace only the genuinely worn ones, rather than swapping all of them at once.
Pros
- Carbide tips hold an edge far longer than steel in gritty soil and wood
- Mounting bolts included, so replacement happens in one session
- Small, cheap, storable — no reason not to keep spares
- Restores cutting speed immediately; dull teeth are the most common cause of “my grinder is weak”
Cons
- Three teeth is a partial refresh, not a full wheel set for an 8- or 12-tooth cutter
- Fit is model-specific; a wrong shank profile will not seat in the pocket
- No performance gain if the real problem is a worn wheel bearing or a slipping drive belt
How it compares
Against the tpengine 12-pack, the Chumia kit is the smaller, more targeted purchase: three teeth and bolts for a partial refresh, versus twelve teeth in 1/2 in x 1/2 in for a larger wheel. If you are replacing an entire 8- or 12-tooth wheel at once, the 12-pack is the better value per tooth. Against the SYWAN 20-pack, the trade is the same but larger again — SYWAN is bulk spares for someone maintaining a machine season after season, while Chumia suits the homeowner doing one replacement and putting the tool away. Start with the three-pack if you have never replaced teeth before; the first replacement teaches you the profile and torque you need.
5. Miskall Stump Remover Angle Grinder Carving Disc – Best for Aggressive Slot Cutting in Small Stumps
The Miskall disc is the aggressive end of the angle-grinder carving category: a 6-tooth, chainsaw-style cutter intended for wood removal at a rate that carbide shaping discs cannot match. If you have a 5–8 in stump, a grinder, and no interest in renting a machine, this is the tool that gets closest to real removal — with the caveat that “closest” is still a long way from a walk-behind grinder, and that the cutting action is far more violent.
Key specs
- Tooth count: 6
- Cutting style: chainsaw-style cutter teeth on a disc body
- Mount: angle grinder
- Intended use: wood shaping, stump removal on small stock, milling-style cuts
- Verification before mounting: disc bore against your spindle, and the disc’s stamped maximum RPM against your grinder’s no-load speed
Strengths
Six teeth is a deliberate compromise. Fewer, larger teeth take a bigger bite per revolution, which removes material faster than a fine-toothed shaping disc but produces more vibration and a rougher finish. For stump work, that trade is usually correct: you are not trying to produce a smooth surface, you are trying to get 6 in of stump below grade.
The chainsaw-style geometry also means the disc cuts a defined kerf rather than scraping. In practice that lets you plunge-cut a grid pattern across a small stump top — a series of parallel slots, then break out the remaining webs — which is a much more efficient way to remove a 6 in stump with a grinder than trying to plane the whole surface down.
It is also genuinely useful beyond stumps. The same disc handles shaping a bowl blank, flattening a slab, or carving out a rotted section of a beam, which is why the category exists at all. You are not buying a single-purpose tool.
Pros
- Fastest material removal of the angle-grinder options in this list
- 6-tooth layout cuts a defined kerf, enabling grid-and-break removal on small stumps
- Useful for general wood shaping and carving, not just stumps
- Compact and storable; no fuel, no engine maintenance
Cons
- Aggressive kickback risk — chain-style cutters grab hard if presented at the wrong angle
- Requires guard removal on most grinders, which increases exposure to thrown debris
- Only realistic for stumps up to roughly 8 in, and slow even then
- Rough finish compared with carbide shaping discs
How it compares
Against the Honoson 22-tooth chain disc, the Miskall’s 6 teeth are the calmer option: fewer teeth per revolution means a smaller, more controllable bite. The Honoson removes material faster but is the more demanding tool to hold. Against the GBSCLOVER 6-tooth grinding disc, both are six-tooth designs, but the GBSCLOVER is specified with a 16 mm center hole, which suits a different spindle standard — so the deciding factor between them may simply be which one fits the grinder you own. If your grinder takes a 22 mm arbor, the Miskall is the practical choice; if it takes 16 mm, the GBSCLOVER is.
6. GBSCLOVER Wood Grinding Disc – Best Budget Disc for 16 mm Spindle Grinders
Most angle-grinder carving discs in the budget tier are built around the 22 mm arbor that dominates the North American market, which leaves owners of grinders with a 16 mm spindle shoulder hunting for something that fits. The GBSCLOVER is that something: a 6-tooth steel wood grinding and shaping disc with a 16 mm center hole, intended for grinding, polishing and shaping wood, including stump and root work.
Key specs
- Tooth count: 6
- Center hole: 16 mm
- Body material: steel
- Function: grinding, shaping and polishing wood
- Check before mounting: confirm 16 mm matches your spindle shoulder or that the correct reducing bushing is available; confirm the disc’s RPM rating exceeds your grinder’s no-load speed
Strengths
Fit is the feature. A disc that does not sit concentric on the spindle is dangerous and useless, and if your grinder’s spindle is 16 mm, a 22 mm disc is not an option no matter how good its tooth geometry is. This disc solves that specific problem at the lowest price point in the category.
The six-tooth steel layout is a reasonable middle ground for shaping work. It removes material at a moderate rate with less of the grab-and-jump behavior of high-tooth-count chain discs, which makes it more forgiving for someone who has not used a carving disc before. For flattening a stump top, dressing a root flare, or shaping a piece of green wood, the control matters more than the raw removal rate.
Steel construction also means the disc can be touched up with a file in a way that is awkward on some carbide geometries, though steel will not hold an edge as long in soil-contaminated wood. For clean-wood shaping it is a perfectly serviceable material.
Pros
- 16 mm bore fills a real compatibility gap in the budget tier
- Six teeth give a more controllable bite than 20-plus-tooth chain discs
- Cheapest way into powered stump and root shaping if the grinder is already owned
- Steel body can be touched up rather than replaced
Cons
- Steel edge life is shorter than carbide in gritty or soil-covered wood
- 16 mm bore does not fit the more common 22 mm arbor without an adapter
- Not a removal tool for anything beyond small stumps
- Requires the same guard-removal compromise as every carving disc
