Abstract

An attachment for a tractor includes a rotary reducing component including a plurality of cutters; a hydraulic system having an activated state, a semi-activated state, and a deactivated state; an inlet, an outlet, a hydraulic motor positioned between the inlet and outlet and being mechanically coupled to the rotary reducing component; a first sensor positioned at the inlet for sensing parameters of the activated, semi-activated, or deactivated states; a hydraulic brake positioned downstream of the hydraulic motor configured to restrict flow from the motor to provide hydraulic motor braking only in the deactivated state; and a controller in communication with the first sensor and the hydraulic brake, wherein the controller triggers the hydraulic brake only when the controller determines the first sensor senses a parameter of the hydraulic system being in the deactivated state.
