More Control Using Advanced Features

John Deere rotary cutters efficiently clear brush and hardwoods up to 10 in. (25.4 cm) in diameter, featuring a hydraulic valve that halts blade rotation within seconds. They also offer enhanced durability and performance through a direct-drive bearing, protective motor cover, and an optional blade load pressure gauge.

Overload Protection With Pressure Gauge

Equipped with a highly visible pressure gauge, the rotary cutter prevents overheating and overloading by allowing operators to monitor blade load. This feature is designed for continuous productivity with reduced stalling instances.

Cut in both directions with the triple bi-directional blade design

The triple bi-directional blade design helps to balance for smooth operation and cutting efficiency. Blades are made of 0.75-in. (19-mm) thick high-grade steel and allow the operator to cut in both directions.
