Abstract: A wood chipper comprises a frame, an infeed system, a rotatable cutting system, and at least one feed wheel disposed between the infeed system and the cutting system to feed wood material to the cutting system. The wood chipper also includes a winch comprising a winch line having a first end, and a collar disposed adjacent the first end of the winch line. The wood chipper further includes a detector adapted to detect a first and a second position of the winch line, wherein the detector is adapted to allow operation of the at least one feed wheel and prohibit operation of the winch when the first position of the winch line is detected, and to allow operation of the winch and allow operation of the at least one feed wheel in a predefined manner when the second position is detected. The wood chipper further comprises a bypass for operation of the at least one feed wheel.

Abstract: A knife assembly for a waste processing system comprises a plurality of cutters disposed on a drum. The cutters further comprise a cutter body, a knife assembly including a first clamp, a second clamp, and a knife. The knife is removably affixed between the first and second clamp and has at least one cutting surface which extends beyond respective ends of the first and second clamps, whereby the cutter body and knife assembly are operably disposed on a drum for a waste processing system.

Abstract: a waste processing machine for reducing wood waste comprises an accumulator operatively connected to the cutting system so as to power the cutting system upon discharge thereof. The accumulator is adapted to receive, store, and release a charge developed from a charging device operatively connected to the accumulator and one or more systems of the waste processing machine.

Abstract: A waste processing system includes a cutting system and a feed system, wherein the improvement relates to a safety and control system which comprises a foot actuated actuator having at least two operable positions, wherein the actuator is in communication with the waste processing system and is adapted to selectively control the operation thereof.

Abstract: A reversing automatic feed assembly for a stump grinder includes at least one sensor adapted to sense excessive load placed on the stump grinder and output a signal thereof. The reversing automatic feed assembly also includes a control system operatively connected to the least one sensor to automatically reverse feed movement of the cutting assembly in response to the signal from the at least one sensor.

Abstract: A remote control assembly for an infeed area of a wood chipper includes an infeed mechanism(s) associated with the infeed area of the wood chipper and a control system operatively connected to the infeed mechanism(s). The remote control assembly also includes a receiver connected to the control system for receiving a signal and activating the infeed mechanism(s).

Abstract: A multiple wheel feed wheel assembly for wood chipper includes an infeed chute and a rotatable cutting assembly spaced from the infeed chute. The multiple wheel feed wheel assembly also includes a first feed wheel disposed between the infeed chute and the cutting assembly. The multiple wheel feed wheel assembly further includes a second feed wheel spaced longitudinally between the first feed wheel and the infeed chute to feed wood material to the first feed wheel.

Abstract: An adjustable tension feed wheel assembly for wood chipper includes a first feed wheel and a movable second feed wheel movable relative to the first feed wheel. The adjustable tension feed wheel assembly also includes a spring operatively interconnecting the first feed wheel and the second feed wheel to urge the second feed wheel toward the first feed wheel. The adjustable tension feed wheel assembly further includes an adjustment mechanism to delay a tension of the spring to allow the second feed wheel to move away from the first feed wheel against a force of gravity before the spring applies a spring force to the second feed wheel to urge the second feed wheel toward the first feed wheel.

Abstract: A wood chipper includes a housing having an inlet and an outlet and a cutting assembly disposed within the housing between the inlet and the outlet and a chute disposed about and overhanging the outlet to form a space therebetween.

Abstract: A drum assembly for a wood chipper includes a drum rotatable about a horizontal axis and a plurality of pockets disposed circumferentially about the drum. The drum assembly also includes a plurality of blades operatively connected to the drum, one of the blades partially overlapping one of the pockets. Each of the pockets has a depth greater than a width thereof and a capacity to hold a wood volume of a maximum size of wood being chipped.

Abstract: A hood assembly for wood chipper includes a housing and a cutting assembly partially disposed within the housing. The hood assembly also includes a first hood partially enclosing the cutting assembly and fixedly connected to the housing and a second hood pivotally connected to the housing and having a closed position covering the cutting assembly and an open position extending away from the cutting assembly. The hood assembly further includes a removable hood pin to secure the first and second hoods together in the closed position and a hood pin plunger assembly connected to the first hood and cooperating with the hood pin and having a bent handle to allow an operator to actuate the hood pin plunger assembly to remove the hood pin after the cutting assembly has stopped rotating to move the second hood to the open position.

Abstract: A waste reducing machine, such as a wood chipper, is constructed having a powered cutting system which includes a control, a powered feed system which includes a control, and an infeed chute. The waste reducing machine includes the combination of an actuator mounted to the machine extending partially into the infeed chute and a safety device in communication with the actuator to stop or reverse the motive power directed to the cutting system, feed wheels, or both by means of a linkage interconnecting said actuator with the control of either or both of the feed and cutting systems.
