CAT CLASS: HQ-10555

60-100 hp Stump Grinder

The 60-100 hp stump grinder band comprises big self-propelled machines engineered for production removals and large-diameter stumps requiring deep grinding well below grade. These machines deliver substantially more power and weight than the 30-60 hp class, enabling aggressive cutting on commercial tree-service routes and land-clearing operations. They sit one rung below the 100+ hp class, which adds tow-behind capability and even greater capacity for the largest stumps.

Spécifications clés

Spécification	Plage typique	Signification
Engine power	50–74 hp	Higher horsepower sustains cutting speed on large-diameter hardwood stumps and permits deeper grinding without bogging.
Operating weight	1,770–2,480 kg (3,900–5,460 lb)	Heavier chassis provides stability during high-torque cutting and anchors the machine when grinding well below grade.
Fuel capacity	12–25 gal (45–95 L)	Larger tanks support extended run times on multi-stump jobsites without frequent refueling interruptions.

Comment choisir

The 60-100 hp class is appropriate for high-volume tree services and land-clearing contractors who regularly encounter stumps exceeding 30 inches in diameter and need to grind 12 inches or more below grade. Operators working mostly residential lots with stumps under 24 inches and shallow grind requirements will find the 30-60 hp Stump Grinder more maneuverable and economical. For the largest stumps—over 48 inches or requiring removal of extensive root systems—the 100+ hp Stump Grinder delivers the power and often the tow-behind convenience needed for utility and municipal projects.

Ce que cette taille peut gérer

Production stump removal on commercial tree-service routes with multiple large-diameter stumps per day
Land-clearing projects requiring stumps ground 12–18 inches below grade for grading or replanting
Removal of 30–48 inch hardwood stumps in parks, golf courses, or institutional grounds
Utility right-of-way maintenance where stumps must be eliminated below future pavement or infrastructure
Post-storm cleanup operations processing numerous large stumps across municipal properties
Residential subdivisions clearing mature tree stumps ahead of construction grading

Sécurité et opération

Self-propelled transport demands operator training on slope navigation, ground conditions, and emergency shutdown procedures
Cutting wheels spinning at high torque create substantial debris ejection hazard; clear work zones and barrier placement are critical
Operating weight above 1,700 kg requires attention to ground bearing pressure on soft soils, lawns, and recently disturbed terrain
Hydraulic cutter-head controls and emergency stops must be tested daily; mechanical failures at this power level pose significant injury risk

Transport et logistique

Typically transported on tandem-axle or tri-axle equipment trailers rated for 6,000–8,000 lb gross load
Most units require a 3/4-ton or 1-ton pickup truck with appropriate towing capacity; combined trailer and machine weight often exceeds 10,000 lb
Self-propelled drive systems allow machines to load onto trailers under their own power using ramps or tilt-deck trailers

Alimentation

Diesel or gasoline engines in the 50–74 hp range; diesel predominates for extended duty cycles and fuel efficiency
Fuel tanks in the 12–25 gallon range typically support 4–8 hours of intermittent grinding depending on stump density and depth
No external electrical or hydraulic hookups required; machines are fully self-contained for remote site operation

Questions fréquentes

What differentiates this class from 30-60 hp machines in practical terms?

The 60-100 hp class adds 20–30 horsepower and 500–1,000 kg of weight, enabling sustained grinding on stumps over 30 inches in diameter and depths exceeding 12 inches below grade without frequent repositioning or blade stalling.

Can machines in this range access residential backyards through standard gates?

Most models are 35–40 inches wide and can pass through 36-inch or wider gates, though their weight may damage soft lawns or irrigation systems; narrower 30-60 hp units are preferred where turf protection is a priority.

How does fuel capacity affect daily productivity on multi-stump jobs?

Machines with 20–25 gallon tanks typically run a full workday grinding 8–12 large stumps without refueling, while 12-gallon models may require mid-day fuel stops, adding 15–30 minutes of downtime on high-volume routes.
