CAT CLASS: HQ-10554

30-60 hp Stump Grinder

The 30-60 hp stump grinder is the workhorse of professional tree service operations, designed for large residential stumps and mid-sized commercial work. These machines bridge the gap between compact walk-behind units and heavy-duty production grinders, offering cutting depths of 38-64 cm and cutter wheel diameters of 43-61 cm. Available in both towable and self-propelled configurations, this size class balances maneuverability with the power needed to handle stumps up to 90 cm in diameter.

Especificaciones clave

Especificación	Rango típico	Qué significa
Engine Power	26-56 hp	Sufficient torque for hardwoods and continuous operation on stumps 60-90 cm diameter
Cutting Depth	15.0–25.2 in (38–64 cm)	Reaches below grade to eliminate surface roots and prepare sites for replanting
Cutter Wheel Diameter	16.9–24.0 in (43–61 cm)	Larger wheels carry more teeth and maintain cutting speed in dense wood
Operating Weight	1,323–3,968 lb (600–1,800 kg)	Heavy enough for stability during grinding yet light enough for standard trailers
Fuel Capacity	6-15 gal (23-55 L)	Supports 4-8 hours of continuous operation between refueling

Cómo elegir

This size class is appropriate for tree service companies handling multiple large residential stumps per day, as well as contractors clearing building sites with stumps up to 90 cm in diameter. The 30-60 hp band offers the power and cutting capacity to work through hardwoods efficiently while remaining transportable on standard trailers. When stumps are predominantly under 50 cm or access is restricted to narrow gates and tight residential yards, the 15-30 hp Stump Grinder provides better maneuverability. For land-clearing operations, commercial site development, or stumps routinely exceeding 90 cm, the 60-100 hp Stump Grinder delivers faster production and deeper cutting capacity.

Self-propelled units load onto tandem-axle trailers rated 1,800-2,300 kg capacity
Transport width typically 1.5-2.1 m, fitting through residential gates and along sidewalks after unloading

No external power required; machines are fully self-contained

Preguntas frecuentes

What is the largest stump diameter this size class can handle?

Most 30-60 hp grinders effectively process stumps up to 90 cm in diameter. Larger stumps require multiple passes and significantly longer grinding time, making the 60-100 hp class more efficient for routine work above that threshold.

How does cutting depth affect site restoration work?

The 38-64 cm cutting depth in this class allows grinding 20-30 cm below finished grade, which is sufficient to eliminate surface roots and permit soil placement for turf or planting. Deeper grinding requires the 60-100 hp or larger classes.

What distinguishes towable from self-propelled models in this horsepower range?

Towable units are pulled behind a vehicle and positioned manually, ideal for open sites. Self-propelled models have integrated drive systems for navigating slopes, soft ground, and tight spaces, common in residential tree service where stumps are scattered across properties.
