Abstract: An implement mounting system for providing a lightweight structure capable of moving along 3 main axes for use upon small to mid-sized tractors. The implement mounting system includes a support frame having a pair of side supports and a rear support, a ball joint attached to the rear support, and a support arm movably attached to the ball joint for rotating about 3 main axes. A brace member is attached between the support frame and the support arm for reducing the amount of side-to-side movement of the support arm. The ball joint is comprised of a ball-and-socket structure for providing various pivoting movements of the support arm.

Abstract: An implement pitch-yaw system for effectively and efficiently controlling the pitch of an implement. The implement pitch-yaw system includes a first yaw actuator and a second yaw actuator attached between an implement structure pivotally attached to a support structure and a connecting member slidably attached to the support structure, and a pitch actuator attached between the connecting member and the support structure. The extension/retraction of the pitch actuator moves the yaw actuators accordingly thereby creating the desired pitch movement for the implement structure.

Abstract: A sliding quick attach system for allowing sliding movement of the implement while providing quick attachment and release of the implement. The sliding quick attach system includes a support frame, a first brace and a second brace extending upwardly from the support frame, a catch member attached to the upper ends of the braces, a first latch structure and a second latch structure attached near opposing ends of the support frame, and an implement unit having an upper lip and a lower lip with at least one slot. The locking pin of the latch structure slidably extends within the slot within the lower lip of the implement unit for retaining the implement unit while allowing side-to-side movement of the implement unit.

Abstract: A front three-point hitch system for allowing a hood and grill of a tractor to be opened free of obstruction. The front three-point hitch system includes a pair of support plates attachable to a tractor frame, a pair of cuff members extending inwardly from the support plates about a pair of opposing apertures, a support structure pivotally attached between the pair of support plates by a pivot pin, a pair of extended tubular supports extending outwardly from the support structure about an aperture positionable within the cuff members, a main pin removably extendable through the apertures within the support plates and the support structure, a pair of support arms pivotally attached to the support structure, and a pair of hydraulic cylinders connected between the support structure and the support arms for effecting movement of the support arms with respect to the support structure.

Abstract: A connector assembly for three-point hitch for conveniently receiving and securing the hitch of an implement to a three-point hitch. The connector assembly for three-point hitch includes a claw member having a receiver groove, and a locking lever pivotally attached to the claw member. The locking lever includes a handle, a front edge and a locking edge, wherein the locking edge engages and retains a connecting shaft within the receiver groove during operation. The front edge of the locking lever is engaged by the connecting shaft during insertion thereby moving the locking lever into an open position allowing free insertion of the connecting shaft into the receiver groove. An aperture within the claw member and the locking lever allows the insertion of a securing pin to ensure the locking lever retains the connecting shaft within the receiver groove during operation of the implement.

Abstract: A replaceable tire gripping system for endless track for extending the useful life and operation of an endless track with grouser members. The inventive device includes a grouser bar having a first side and a second side, a pair of side walls attached to opposing ends of the grouser bar, a plurality of openings within the grouser bar, a plurality of grip members positionable within the plurality of openings with a portion exposed through the second side of the grouser bar, and a wear plate attached to the first side of the grouser bar for retaining the grip members within the openings. The openings and the grip members are preferably tapered for allowing the broad end of the grip members to be substantially flush with the first side and the wear plate.

Abstract: An adjustable three-point hitch for allowing a user to hydraulically manipulate the rotational position of an implement with respect to a longitudinal axis of the tractor. The inventive device includes a support frame attachable to a front portion of a tractor frame, a pair of lift arms pivotally attached to the support frame, a pair of lifting cylinders fluidly connected in parallel and attached between the support frame and the pair of lift arms, a center arm pivotally attached to the support frame, a tilting arm having a slot pivotally attached to one of the lift arms, an engaging member extending from the opposing lift arm within the slot, and a tilting cylinder attached between the support frame and the tilting arm for manipulating the tilting arm. To adjust the position of the lift arms with respect to one another, the tilting cylinder is extended or retracted until the desired position is reached.

Abstract: An self-cleaning endless track which reduces slippage between the tires of a skid-loader and the endless track. The inventive device includes a plurality of track pads interconnected, wherein each track pad comprises a pair of grouser members extending parallel between a pair of opposing side members, a pair of slots on opposing sides of the side members for pivotally receiving a link member, and a corresponding pair of gripping members attached to an upper surface of the pair of grouser members. The gripping members reduce slippage between the tires of the skid-loader and the endless track, thereby extending the useful life of the skid-loader.

Abstract: A self-cleaning track for reducing the accumulation of debris between the moving and non-moving components of an endless track. The inventive device includes a plurality of track pads interconnected to form an endless track. Each track pad comprises at least one grouser member extending between a pair of opposing side members, a cavity within each of the side members, an opening projecting into a side of each side member exposing the cavity, a pair of slots on opposing sides of the side members for pivotally receiving a link member, and a ramp portion projecting into each side member from the a lower portion of the slots. The opening allows debris accumulated within the cavity to escape freely. The ramp portions of the slots allow the debris to descend from the cavity when the track pad is in a substantially upper position along the endless track.

Abstract: A track pad, a plurality of which when interconnected comprise an endless track for entrainment about a pair of tandem tired wheels, each track pad having a pair of spaced downwardly diverging transversely extending grouser bars and a single rigid link at each side fixed at one end to a tire protective plate which carries the grouser bars, and pivotally connected at its other end to the pin of a fixed clevis carried by the corresponding tire protective plate of the adjacent track pad, the fixed link and clevis at each side being the sole interconnecting means between adjacent track pads.
