Cuts up to 6″ diameter trees and exposed blades allow faster cutting for a maintained finish.
DO NOT OPERATE CUTTER WITHOUT A SHATTERPROOF CAB ON LOADER.

The V50 Open Front Rotary Brush Cutter uses double-sided 5” x ⅝” blades that are reversible for longer life.
No, there are no options for casters or a rear roller for the V50 Rotary Brush Cutter with Open Front Deck.
The V50 Open Front Rotary Brush Cutter is designed to rough cut large, dense brush and trees up to 6” in diameter.
No. Running the flywheel system in reverse will cause the cutter to cut poorly, easily stall, and have minimal torque.
The Rotary Brush Cutter is designed to spin counter-clockwise and takes 7-10 seconds to come to a complete stop. If the flywheel is running in reverse, slow down will be much faster and very loud.
Operating the Rotary Brush Cutter’s flywheel counter-clockwise is essential for proper operation and preventing damage to the cutter’s blades and motor.
The spindle is the most expensive performance component on a skid steer brush cutter. It is responsible for smoothly transferring power from the hydraulic motor to the flywheel and absorbing impact that could damage the hydraulic motor.
High-performance skid steer brush cutters require heavy-duty spindles to ensure reliability and productivity.
Standard pressure relief valves protect the motor and the loader’s hydraulic system from damaging pressure spikes. When the maximum pressure point is reached, the valve opens to prevent pressure from rising any further. This prevents seals or other internal components from breaking due to excessive pressure.
Skid steer brush cutters are capable of throwing debris over 200 feet and can cause serious bodily harm or death if not used with a shatterproof cab.
For efficient operation, purchase a skid steer brush cutter with a cut width that is wider than the tires or tracks of your loader.
Loader capacity should also be considered. Selecting a skid steer attachment that is too wide will add weight, volume, and surface area, all factors that could affect performance.
Generally, higher GPM is better. Higher GPM provides more torque which prevents the cutter from losing power as easily and allows the cutter to return to cutting speed faster. There may be situations in which this is not true. For more information, contact a DTE Equipment.
