A stump left in the ground keeps sending up shoots, attracts termites and rot, and sits in the way of mowing or replanting for years if you don’t deal with it. Renting a stump grinder for a single job makes sense if you’ve got one stump, ever. Past that, owning one starts to pay for itself, provided you buy the right category of machine for how you’ll actually use it. This guide breaks down 9 real gas stump grinders, organized by what actually differentiates them.
Walk-Behind vs. Tow-Behind vs. PTO – Match the Machine to the Job
Every stump grinder falls into one of three basic categories. Walk-behind models carry their own gas engine and are pushed by hand from stump to stump, the standard choice for occasional residential use, roughly one to ten stumps a year. Tow-behind models are larger, still self-contained with their own engine, but hitch to a truck or ATV for transport between job sites, better suited to higher-volume work or larger properties where pushing a machine any real distance isn’t practical. PTO-driven grinders skip the separate engine entirely and attach to a tractor’s 3-point hitch, drawing power from the tractor’s own PTO shaft, the most cost-effective option if you already own a tractor in the right horsepower range, since you’re not paying for a second engine you’ll rarely use elsewhere. None of the products in this guide are PTO units, all nine here are self-contained walk-behind or towable gas machines, but it’s worth knowing the category exists if you already own a tractor.
Cutting Wheel Size, Teeth Count, and Teeth Material
Wheel diameter determines how much material the machine removes per pass, but a bigger wheel with fewer teeth isn’t automatically faster than a smaller wheel with more. Teeth material matters more for long-term cost: carbide and tungsten teeth hold a cutting edge significantly longer than basic alloy teeth, especially in harder wood or rocky soil, and several models in this guide use systems where the teeth rotate to a fresh edge in place rather than needing full replacement, worth checking for on any grinder you’re buying for repeated use.
Grinding Depth and Height – What the Specs Actually Mean
Manufacturer specs usually list two separate numbers: height above ground and depth below ground. The above-ground figure tells you how tall a stump the machine can tackle without pre-cutting it down; the below-ground figure tells you how completely you can eliminate the stump for regrowth prevention and mower clearance. For a clean landscaping result where you’re reseeding or replanting over the spot, prioritize below-ground depth over above-ground height, most residential jobs need 8-12 inches below grade to stop resprouting and let grass grow back evenly.

1. “THE AMERICAN” SGR389RTE Swivel Head Stump Grinder – Best Overall
Built around a genuine 13HP Honda GX390 engine with electric start, this is the deepest-reaching machine in this guide at 24 inches above ground and 12 inches below, backed by tungsten carbide teeth and a swivel head that sweeps side to side over the stump instead of requiring the whole machine to be repositioned. A 270-degree adjustable handle adds real control in tight backyard spots, and auto shut-off levers stop the machine the instant they’re released. Manufactured in Louisville, Kentucky.
Pros: Deepest grinding range in this guide (24″ above / 12″ below); genuine Honda GX390 engine with electric start; swivel head sweeps side to side without repositioning; North American made.
Cons: Premium price relative to the FORESTWEST, which matches similar grinding range for less; heavier machine given the full-size Honda engine.
Best for: buyers who want the deepest grinding range in this guide paired with a genuine Honda engine, from a North American-made machine.
2. Genuine OEM 13HP Walk-Behind Dosko Stump Grinder – Best Premium / Most Established Brand
Dosko is the name professional rental yards and landscaping crews reach for first in this category, and this model shows why: a 13HP Honda GX390 engine, Greenteeth 700-series teeth that rotate through three separate 120-degree cutting edges before needing replacement, a cyclone air cleaner, an oil shutdown sensor, and a narrow 32-inch width that fits through standard gates and walkways most competitors can’t clear. Backed by a 3-year engine warranty.
The trade-off for that reputation is price, this sits at the premium end of this guide, a cost that’s easier to justify for frequent or commercial use than for a single backyard stump.
Pros: Greenteeth rotate through 3 separate cutting edges before needing replacement; narrow 32″ width clears gates most competitors can’t; cyclone air cleaner and oil shutdown sensor; 3-year engine warranty; the brand professional rental yards trust first.
Cons: The most expensive machine in this guide; overkill for a single backyard stump rather than frequent or commercial use.
Best for: landscapers, rental fleets, and anyone using a stump grinder often enough that Dosko’s rotating-tooth system and narrow-gate access genuinely save time and money over a full season.
3. FORESTWEST 11075, 13-Inch Stump Grinder – Best Value 15HP
A 15HP 420cc engine driving 9 heavy-duty tungsten tip teeth, with a genuinely useful 24-inch above-ground / 12-inch below-ground grinding range that matches the premium AMERICAN pick above at a lower price point. Testing under demanding hardwood conditions backs up the power claim, this isn’t an underpowered budget engine wearing a 15HP label.
Pros: Matches the premium picks’ 24″/12″ grinding range at a lower price; genuine 15HP power verified under demanding hardwood conditions; 9 tungsten tip teeth.
Cons: Less established brand name than Dosko or Honda-engine competitors; fewer premium convenience features like a swivel head or sweep function.
Best for: buyers who want the same grinding depth as the premium picks in this guide without paying premium pricing.
4. Superhandy 15HP Gas-Powered Stump Grinder – Best Ergonomic Features
The standout here is genuine usability engineering rather than raw specs alone: a sweep function that lets the cutting head glide across the stump without repositioning the whole machine, plus an adjustable angled and foldable handle that both improves ergonomics during use and shrinks the machine’s footprint for storage between jobs. Electric start and 8 tungsten carbide teeth round out a well-equipped 420cc, 15HP package.
Pros: Sweep function glides the cutting head across the stump without repositioning the machine; foldable handle saves real storage space; electric start; 8 tungsten carbide teeth.
Cons: Doesn’t list a below-ground depth figure as clearly as some competitors; ergonomic features add cost versus a no-frills 15HP unit.
Best for: buyers who store their grinder in a garage or shed between uses and want the fold-down handle’s space savings, plus the sweep function’s reduced physical effort during grinding.
5. Crary Bear Cat SGACE Stump Grinder, 208cc – Best Smaller Engine
Bear Cat is another established commercial equipment brand, and this smaller-displacement 208cc model brings genuine commercial construction down to a lighter package: a 10-gauge steel body, 8 carbide Greenteeth on what the manufacturer describes as the industry’s thickest rotor in its class, and 13-inch wheels with a proper brake drum and band, a real stopping mechanism most budget competitors skip entirely.
Pros: Genuine wheel brake drum and band, a feature most budget competitors skip; established Bear Cat commercial brand; 10-gauge steel body and thick rotor.
Cons: Smaller 208cc engine has less raw power than the 15HP options in this guide; not the choice for large, dense hardwood stumps.
Best for: buyers who want established-brand build quality and a genuine wheel brake without stepping up to a full 15HP engine.
6. MachPro 15HP Commercial Stump Grinder – Best Towable
A 420cc, 15HP engine paired with a 12-inch cutting wheel and 9 tungsten teeth, built specifically around towability: an integrated tow bar and disc brake system make this the most straightforward machine in this guide to move between properties or across a larger lot without pushing it by hand. Electric start rounds out the package.
Pros: Integrated tow bar and disc brake make it genuinely easy to move between properties; electric start; 9 tungsten teeth.
Cons: 12″ cutting wheel is smaller than the 13-15″ wheels on several competitors; towing capability adds no value if you’re only working one property.
Best for: landscapers or property owners covering multiple stumps across a larger area who want to tow rather than push between locations.
7. BILT HARD 24″ Gas-Powered Stump Grinder – Best Cutting Height
A 420cc, 15HP engine with electric start, 9 alloy teeth, and a genuinely tall 24-inch cutting height paired with 10 inches of below-ground depth. The swinging chassis design lets the cutting head pivot across the stump similarly to the swivel-head and sweep-function machines above, and a dual wheel brake system adds real stopping control that budget-tier competitors often lack.
Pros: Tall 24″ above-ground cutting height; swinging chassis pivots across the stump like the swivel-head competitors; dual wheel brake system for real stopping control.
Cons: 10″ below-ground depth is shallower than THE AMERICAN and FORESTWEST’s 12″; alloy teeth wear faster than the tungsten or carbide teeth on several competitors.
Best for: taller stumps that haven’t been pre-cut down, where the 24-inch above-ground reach matters as much as depth below grade.
8. SuperHandy 9HP Gas Stump Grinder – Best Compact/Lightweight
The smallest engine in this guide at 9HP, paired with a direct belt drive system that eliminates clutch slippage, delivering the cutting wheel’s full torque rather than losing power through a slipping clutch the way some budget competitors do. Six carbide teeth on a 12-inch wheel handle smaller residential stumps well, and the lightweight, compact frame is noticeably easier to maneuver and transport than the 15HP machines in this guide.
Pros: Direct belt drive eliminates clutch slippage, delivering the wheel’s full torque; noticeably lighter and easier to maneuver than the 15HP machines; 6 carbide teeth.
Cons: Smallest engine in this guide at 9HP, not suited to large or dense hardwood stumps; 12″ wheel is on the smaller end for above-ground reach.
Best for: smaller residential stumps and buyers who prioritize a lightweight, easy-to-transport machine over maximum cutting power.
9. MechMaxx 12 Inch DUCAR Stump Grinder, SGR1500 – Best Value / EPA-CARB Certified
A 420cc, 15HP DUCAR engine with EPA Phase III and CARB Phase III emissions certification, worth knowing if you’re in a state with stricter small-engine emissions rules. Eight alloy teeth on a 12-inch cutting wheel handle 10 inches of below-ground depth and 12 inches above, with Kevlar drive belts and a drum brake rounding out a well-specified machine at a competitive price.
Pros: EPA Phase III and CARB Phase III emissions certified; Kevlar drive belts and a drum brake; 15HP power at a competitive price.
Cons: 12″ above-ground height is the shortest reach in this guide, best for stumps that are already cut low; alloy teeth wear faster than tungsten or carbide.
Best for: buyers in emissions-regulated states who need documented EPA/CARB certification, or anyone wanting 15HP power at the lower end of this guide’s pricing.
Buying Guide
Matching Engine HP to Your Stumps
9HP handles smaller residential stumps in softer wood without excessive strain. 13-15HP is the sweet spot for most homeowners and light-commercial use, capable of working through denser hardwoods like oak without bogging down. If you’re regularly grinding large, old hardwood stumps, lean toward the higher end of that range rather than the minimum.
Safety Essentials
Eye, ear, and face protection are non-negotiable, stump grinders throw wood chips and debris at real velocity. Clear the area of rocks, buried utility lines, and irrigation before starting, a carbide tooth striking a rock at speed can damage the cutting wheel and send fragments flying. Never operate without the machine’s safety shut-off systems engaged.
Rent vs. Buy
For a single stump, renting is almost always the better economic call, most rental yards charge well under what a mid-range machine in this guide costs. Ownership starts making sense once you’re removing more than two or three stumps a year, or if you’re a landscaper billing the work out to clients.
Frequently Asked Questions
How deep do I need to grind a stump?
For most residential landscaping where you’ll reseed or replant over the spot, 8-12 inches below grade is enough to stop resprouting and let grass or new plantings establish evenly. Deeper isn’t always necessary unless you’re planning to build or pour concrete directly over the location.
Can I rent instead of buying for a one-time job?
Yes, and for a single stump it’s usually the more economical choice. Most hardware stores and equipment rental yards carry walk-behind stump grinders by the day, often at a fraction of a mid-range machine’s purchase price.
What horsepower do I need for a large oak stump?
Lean toward 15HP or higher for dense hardwoods like oak, hickory, or old-growth stumps. A 9HP machine can technically grind hardwood but will take considerably longer and put more strain on the engine and belts than a properly sized unit.
Do PTO stump grinders need a specific tractor horsepower?
Yes, PTO stump grinder attachments are rated for a tractor horsepower range, commonly somewhere in the 15-60HP range depending on the model, and running one outside its rated range either underperforms or risks damaging the attachment or your tractor’s PTO system. Always check the attachment’s rated HP range against your specific tractor before buying.

Whichever machine fits your stumps, don’t skip the safety basics, clear debris, wear protection, and confirm no buried utilities before the first cut. If you’re clearing land more broadly rather than just removing a stump or two, our guides to wood chippers and log splitters cover what to do with everything else the property clearing turns up.
