Abstract: A hydraulically powered implement is designed for use in connection with a tractor that has a hydraulic pump that supplies pressurized hydraulic fluid to the implement. The implement includes a variable displacement hydraulic motor, an operative element driven by the hydraulic motor, a speed sensor configured to measure the rotational speed of the operative element and output a speed signal representative of the measured speed, a shift module that adjusts the displacement of the hydraulic motor in response to a shift command signal, and a controller. The controller sends the shift command signal to the shift module in response to speed signal output by the speed sensor.

Abstract: A tooth for use on a rotating element has a base attached to the rotating element and a cutter assembly removably attached to the base. The cutter assembly has an upper ramp surface and a blade. In another aspect, the tooth has a base attached to the rotating element and the base includes one or more base tab and slot elements. The tooth also includes a cutter assembly that has one or more cutter assembly tab and slot elements. Each of the one or more cutter assembly tab and slot elements is configured for a mating engagement with a corresponding one of the one or more base tab and slot elements. In another aspect, a rotary drum for use on a vegetation cutting machine includes a plurality of teeth that each have a base attached to the rotary drum and a cutter assembly removably attached to the base.

Abstract: A powered mulcher is configured for attachment to a vehicle. The mulcher includes a frame assembly and a drum assembly contained within the frame assembly. The drum assembly includes a substantially cylindrical drum and a cutting array mounted to the drum. The cutting array includes a plurality of flights connected to the drum and a plurality of cutters attached to each of the plurality of flights. The plurality of flights are configured to push processed plant debris away from the ends and middle of the drum.
