Vermeer’s SC852 stump cutter is designed to boost productivity with sizeable cutting width and the ability to maneuver on uneven terrain.
A four-position linkage design allows the cutter wheel to move away from the machine as the boom drops down toward the stump. This reduces the need to reposition the entire unit.
The SC852 achieves cutting heights of 31 in. (79 cm) above ground and 25 in. (64 cm) below grade. The cutter wheel guard remains parallel with the ground so it does not limit movement over obstacles.
The straight line cutting width at ground level is 72 in. (183 cm).
Powered by an 85 hp (63 kW) Cummins Tier III turbocharged diesel engine, the SC852 produces up to 224 ft.-lbs. (203 Nm) of torque and has enough power to tackle large stumps. With a machine width (with outer dual tires removed) of 35 in. (89 cm), the SC852 retains a compact footprint for maneuverability on confined job sites.
Several features enable the stump cutter to maneuver through difficult and uneven ground conditions. A variable displacement pump and a series of flow dividers power the full time four-wheel drive by transferring oil flow and power independently to each wheel motor.
The machine is equipped with a Differential Lock / Unlock feature so the operator can choose between maximum pulling power when ground conditions limit traction or minimum turf disturbance while making tight turns. Front-mounted controls offer maneuverability in confined spaces by allowing the operator to walk in line with the machine.
The cutter wheel drive system, with an engine mounted direct drive hydrostatic pump and gearbox mounted hydraulic motor, eliminates clutch and belt-drive maintenance and reduces cutter wheel stopping time. The cutter wheel stopping time is reduced with no-maintenance hydrostatic braking.
An oscillating steering axle provides 8 in. (20 cm) of wheel travel over obstacles, allowing the SC852 to traverse tough ground conditions while maintaining four-wheel contact. Variable speed control lets the operator choose between a high speed of up to 150 ft. (46 m) per minute for quick maneuverability, or a creep function for better control in confined areas.
A 34-in. (86 cm) wide front-mounted chip blade is standard and can be used to easily move chips around the job site, reducing the need to manually relocated the chips. The rounded lower edge of the blade helps reduce turf damage.
