A wood chip collection system having a stump grinding wheel, a chip chute and a chip collection bin. The chute is positioned such that chips generated by the rotation of the wheel when engaged in a stump will be directed into the chute. The chute, in turn is sized and shaped to permit the energy in the chips to move the chips into a collection bin. The bin is positioned adjacent to and in alignment with the trailing edge of the chute in order to effectively receive the chips.

A stump cutter includes a cutter wheel rotatable about a cutter wheel axis, the cutter wheel supported by a boom for sweep movements about a vertical cutter wheel sweep axis, and the cutter wheel is supported by the boom for tilt movements about a horizontal cutter wheel tilt axis. A prime mover is configured to drive the cutter wheel about the cutter wheel axis. A mechanical driveline provides power transmission from the prime mover to the cutter wheel, the mechanical driveline including a final drive cutter wheel gearbox positioned along the cutter wheel axis, and a swivel gearbox assembly including two right angle gearboxes joined with a swivel joint therebetween. The swivel joint between the two right angle gearboxes forms a driveline swivel axis. A downstream one of the two right angle gearboxes includes an output shaft connected to an input shaft of the final drive cutter wheel gearbox.

A stump cutter includes a mainframe and a cutter wheel supported by a boom and rotatable about a cutter wheel axis spaced from the mainframe. A two-axis gimbal set supports the boom from the mainframe, the two-axis gimbal set supporting the boom for sweep movements of the cutter wheel about a vertical cutter wheel sweep axis and for tilt movements of the cutter wheel about a horizontal cutter wheel tilt axis. A prime mover on the mainframe is configured to drive the cutter wheel about the cutter wheel axis. A mechanical driveline is configured to provide power transmission from the prime mover to the cutter wheel, the mechanical driveline including a constant velocity joint.

A stump grinder has a grinding arm that durably mounts a rotatable grinding wheel by securing the drive shaft of a motor to the grinding wheel such that a pair of bearings within the motor support one side of the grinding wheel and by supporting the other side of the grinding wheel with a stub shaft received within a third bearing. The grinding arm is laterally offset on the frame of the stump grinder to have a swing angle that is not symmetrical relative to the width of the frame, but with the swing angle starting at one side of the frame and then traversing across substantially the entire width of the frame to improve the ability of the operator to see the grinding wheel. A single joystick is movable in orthogonal directions corresponding to desired up and down and side-to-side pivoting motions of the grinding arm. The joystick includes a depressible trigger for starting and stopping the operation of the grinding wheel.

An object lifting, pulling and digging apparatus has a pair of jaws that can be opened to enable positioning the jaws around a post, tree, and/or bush then closed around the post, tree, and/or bush. The jaws can then be raised to pull the post, tree, and/or bush from the ground. The jaws of the apparatus can also be closed and angled downwardly to drive the distal ends of the jaws into the ground, where the jaws can then be moved upwardly to dig the post, tree, and/or bush from the ground. The apparatus can easily be attached to a vehicle equipped with a universal quick attach hitch and having auxiliary hydraulics, for example, a “skid steer” type farm or construction vehicle.

A stump cutting assembly mounted to a stump cutting wheel. Stump cutting assembly is a stump cutting tooth interconnected to the wheel by a holder or block that is fixed to wheel by welding or other equivalent process, an optional debris deflector and a fastener that interconnects tooth and deflector to holder. As wheel rotates about its axis of rotation, the tooth cuts away at wood or other debris in which it comes into contact through the side to side and/or longitudinal movement of a stump grinder unit.

A tree and debris pusher for removing and gathering felled trees, such as stands of dead cedar trees, particularly though not exclusively adapted for use on burned land from which dead trees must be cleared. The tree and debris pusher comprises a frame, a pusher bar assembly, a tooth assembly, and plurality of support and connecting structures. The pusher bar assembly forms a generally concave or arcuate shape, including a center section and transverse wings. The tooth assembly extends is contiguous with the pusher bar assembly and comprises a plurality of teeth extruding from therefrom so as to precede the pusher bar assembly in the direction of use of the tree and debris pusher and make first contact with trees and debris which are the object of removal. Support members and connecting members provide additional support and resist loads during operation of the tree and debris pusher. The tree and debris pusher clears trees and debris and piles the dead and debris in a desired location without changing attachments or machinery.

A grinding blade having a blade body, a plurality of tooth mounts, a plurality of cutting teeth, and a plurality of blade stops is disclosed. The blade body has a front surface, a back surface, and a blade mounting hole along a central axis. The tooth mounts and blade stops are integral with the blade body and protrude upward and away from the back surface and the central axis. Each tooth mount has a cutting tooth releasably coupled through a tooth aperture. The blade stops and tooth mounts are equal in number and are distributed alternatingly and with radial symmetry about the central axis. A cross section of the solid of revolution defined by rotating the blade stops about the central axis overlaps with at least two thirds of a cross section of the solid of revolution defined by rotating the cutting teeth about the central axis.
