Stump Grinding Equipment Comparison
A breakdown of stump grinder types, sizes, and when to use each one.
Stump grinding is a significant revenue stream for most tree service companies. The right grinder for your operation depends on the types of jobs you take and the access conditions you work in.
Handlebar (Walk-Behind) Grinders
Small walk-behind grinders with 20 to 35 HP engines fit through 36-inch gates and can access backyards that larger machines cannot reach. They handle stumps up to about 18 inches in diameter efficiently but slow down considerably on larger stumps.
Brands like Vermeer SC252, Carlton SP4012, and Rayco RG27 are popular in this category. Expect to pay $12,000 to $25,000 new.
These grinders are ideal if your market is primarily residential work in fenced backyards. They are also easy to trailer behind a pickup.
Self-Propelled (Track) Grinders
Mid-size tracked grinders in the 35 to 75 HP range are the workhorses of the industry. They are self-propelled, so you drive them to the stump rather than muscling them into position. The tracks provide traction on slopes and soft ground.
Models like the Vermeer SC362, Carlton SP7015TRX, and Bandit SG-40 fall in this range. Prices run $25,000 to $60,000 new.
If you grind stumps regularly (several per week), a track machine pays for itself through time savings and reduced operator fatigue.
Large Self-Propelled Grinders
For high-volume grinding and large stumps, machines in the 75 to 200+ HP range make quick work of big wood. They handle stumps over 36 inches without breaking a sweat and grind deep enough to clear root flares in one pass.
The Rayco RG100X, Vermeer SC852, and Carlton 8018TRX are examples. These run $60,000 to $120,000+ new. They need a dedicated trailer and sometimes a CDL-rated truck to tow.
Teeth and Cutterheads
The cutting system matters as much as the horsepower. Green teeth, Rayco Super Teeth, and carbide-tipped teeth each have their strengths:
- Green teeth: Easy to sharpen in the field, replaceable tips, good in clean wood
- Carbide teeth: Last longer in dirty conditions (rocks, soil), more expensive to replace
Carry spare teeth on every job. A single rock can damage a tooth and slow you down for the rest of the day if you do not have replacements.
Rent vs. Buy
If you grind fewer than 10 stumps per month, renting may be more cost-effective than owning. Rental rates run $250 to $500 per day for mid-size machines. Once you are grinding regularly, ownership makes sense because your per-stump cost drops significantly.
