Abstract: An agricultural implement includes a traction structure and a tool beam rearward of the traction structure. First and second wheeled support structures support the tool beam at opposite respective ends of the tool beam. First and second linkages each have a forward portion connected to the traction structure and rearward portions connected to the first and second support structures respectively. An actuator is effective between the traction structure and the first linkage for selectively adjusting an angular position of the first linkage relative to the longitudinal axis of the traction structure. The tool beam provides a force transmitting connection between the rearward portions of the first and second linkages whereby angular movement of the first linkage relative to the traction structure is accompanied by angular movement of the second linkage relative to the traction structure.

Abstract: The invention is intended to make it possible to reduce the overall lengths of a vertical shaft and a fore/aft shaft, while securing sufficient shaft strengths thereof, so that the vertical dimension from the fore/aft shaft to a tilt cylinder may be formed short and to render the construction on the rear face side of a blade compact. A traveling machine body 2 pivotally supports a dozer frame 3 via a horizontal shaft, the dozer frame 3 being lifted up/down via a dozer cylinder S1. This dozer frame 3 pivotally supports, via a vertical shaft Y, a support body 4 which is pivoted back and forth via an angle cylinder S2, and this support body 4 pivotally supports, via a fore/aft shaft Z, a blade 5 which is vertically pivoted via a tilt cylinder S3. The support body 4 supports the fore/aft shaft Z downwardly and forwardly of the vertical shaft Y, and the tilt cylinder S3 is disposed upwardly and forwardly of the vertical shaft Y and upwardly of the fore/aft shaft Z.

Abstract: The present invention provides a small electrical motor, coupled to the snow plow of a UTV or ATV via a mechanism which allows the plow blade to move in response to unexpected spikes in load. In one embodiment, a braking system is used to absorb the load force. In a second embodiment, a set of pulleys is used in conjunction with a belt, such that the belt will slip in the presence of excessive force. In a third embodiment, a rack and pinion mechanism is used in combination with a spring element to absorb the excessive load.

Abstract: The present invention includes an angle blade assembly capable of angular motion relative to a frame of a work machine. The angle blade assembly includes a blade assembly, a subframe connected to the blade assembly, and an actuating cylinder with a line of action. The subframe includes connecting and lever portions that are connected to define a primary vertical axis. The actuating cylinder is connected to the connecting and lever portions so that a secondary vertical axis is defined between the actuating cylinder and the lever portion. The connection of the actuating cylinder to the connecting and lever portions produces the angular motion of the blade assembly when the actuating cylinder is operated. During the angular motion of the blade assembly, the secondary vertical axis moves about the primary vertical axis and a substantially constant distance is maintained between the line of action of the actuating cylinder and a parallel line extending through the primary vertical axis.

Abstract: The invention is a trailer-type snowplow assembly. The assembly includes one pivot mechanism that allows the plow blade to be raised or lowered. The assembly further includes a free pivot assembly that allows the blade to freely pivot in a transverse direction in response to directional changes of the tow vehicle or uneven snow impact along its length. Also disclosed is a multi-piece plow blade that has removable end portions that allow a user to elongate or shorten the effective length of the plow blade.

Abstract: A vehicle has front brackets which engage with a coupler which has an upright brace with two vertical members joined by a horizontal member. Fixed pins on the brace engage in the bracket slots and retractable spring-loaded pins on the brace engage with the holes on the bracket. A frame is pivotally mounted to the vertical members and is pivotable by an actuator which connects the brace and the frame. A support is pivotally mounted about an axis perpendicular to the frame and has an upturned flange adapted to engage beneath a downturned bracket on the implement and has pinholes located beneath the flange to receive pins extending from the implement. Fixed to the implement is a downturned J-shaped bracket with a vertical portion and a spaced opposed portion which is approximately as deep as the upward extension of the flange on the coupler. Vertical plates are connected on either side of the J-shaped bracket and are spaced to fit on either side of the support of the coupler.

Abstract: An apparatus for mounting a dozer blade for vertical and angular movement relative to a frame of a wheeled implement. The mounting apparatus a mounting mechanism which allows the dozer blade to be mounted close to the wheels to either end of the implement and which permits angular movement of the blade about a generally vertical axis and vertical movement of the dozer blade about a generally horizontal axis. The mounting apparatus further includes a linearly distendable driver which extends laterally across the frame of the implement and a linkage mechanism which improves angling moments and maximizes the driving force imparted to the blade upon extension of the driver. The linearly distendable driver and linkage mechanism operate in combination and in a closely confined area adjacent to the implement frame for effecting extended angular movement of the dozer blade.
