Abstract: An earth working machine includes a drive configuration and a working apparatus releasably connected together by a bolt component. A bolting moment bracing arrangement is connected or connectable in bolting moment-transferring fashion to the bolt component, and includes a bracing region that is embodied for bolting moment-bracing abutment in a bracing bolting direction against a counterpart bracing region, the drive configuration being embodied to be driven to rotate, in a rotation direction codirectional with the bracing bolting direction, while the bracing region is in abutment against the counterpart bracing region.

Abstract: An oblique submerged reverse deep rotary tilling device configured to be connected to a tractor. The tilling device includes a stander, a mounted frame, a gearbox and an oblique blade roller. The oblique blade roller has configured rotary blades whose tips bend to the same direction. The angle between the rotary tilling blade roller and an advancing direction of the tractor is 55˜70° while the rotary blade tips are all toward the right side of the advancing direction. Side force balance blades are installed to the left side of the oblique blade roller, rotate in a plane that is parallel to the advancing direction, and have a rotating center axis disposed at an angle to the oblique blade roller to balance the axial component force of the oblique blade roller.

Abstract: An automatic connection mechanism for a mid-mounted implement to a tractor is disclosed. The automatic connection mechanism includes a rear lift linkage pivotably attached to the tractor, that automatically and releasably engage the rear of the implement. The forward lift linkage is pivotably attached to the front of the implement, and automatically and releasably engages the forward end of the tractor. A PTO coupling member also is attached to the rear lift linkage to engage an opposing PTO coupling member on the implement.

Abstract: A tiller can include a frame supported by at least one wheel. An upright assembly can extend from the frame. A drive mechanism can be supported by the frame and include a motor having an output member. A tilling implement can have a drive shaft that is driven by the output member. The tilling implement can comprise at least one tine plate. A slider assembly can communicate with the wheel and be movably coupled along the upright assembly. The slider assembly can be configured to securably locate in at least a first position wherein the wheel is located at a first elevation relative to the frame and a second position wherein the wheel is located at a second elevation relative to the frame. The first and second elevations can be distinct.

Abstract: An automatic locking ball coupler for a power take off includes a ball keeper connected to the power take off and having a longitudinal axis and openings in a cylindrical surface thereof. Locking balls are received in the openings and can move radially with respect to the axis of the cylindrical ball keeper. A ball collar is positioned around the cylindrical ball keeper and has a plurality of internal circumferential rings and recesses between each ring. The ball collar can slide axially with respect to the longitudinal axis of the ball keeper between a coupled position in which the locking balls are on the rings and an uncoupled position in which the locking balls are in the recesses.

Abstract: A safety system for a riding lawn mower that prevents powered operation of a PTO driven implement while in reverse unless an override switch is “ON”. The override switch may be a sustained action two position switch and the PTO driven implement may be a lawn mower blade. In one embodiment, the override switch does not allow the engine to start if the override switch is on. In one embodiment, the override switch cooperates with an operator presence switch to prevent operation of the PTO driven implement when the override switch is on and the operator is not present.

Abstract: One embodiment of the invention relates to an adapter assembly for a towing vehicle having a drawbar hitch for connecting a towed implement having a pull-through swivel hitch assembly to the towing vehicle. The adapter assembly includes a drawbar extension member having a horizontal cross pin, a clamp assembly to secure the drawbar extension member to the drawbar, an adapter frame having a hook to engage the cross pin, and a trunnion pin to couple the adapter frame to the swivel hitch assembly.

Abstract: A working vehicle includes an engine in the rear of a passenger seat, and a working machine vertically movably disposed in the rear of the engine, wherein an upper end of the working machine which is lifted to the highest position is set lower than an upper end of the engine. As a result, a ventilation in the vicinity of the engine is improved and a cooling effect of the engine is enhanced. Also, a maintenance of the engine can be conducted without being interfered by the working machine. Further, with this arrangement, a center of gravity of the working machine is low, thereby enhancing a stability of the working vehicle, and a driver or a passenger of the vehicle can visually check backward much easier.

Abstract: A rotary cultivating apparatus wherein a tiller frame having a rotary tiller unit is laterally shiftable relative to a fixed frame having connecting portions for a vehicle and a power input shaft. A mechanism for laterally shifting the tiller frame comprises a transmission gear member mounted on a transmission shaft for the tiller unit and having an inner gear and an outer gear, a shifting screw rod reversibly rotatable by the transmission gear member through intermediate gears, and an internally threaded member fixed to tiller frame and in screw-thread engagement with the screw rod. One of the intermediate gears is selectively meshable with the transmission gear member to shift the tiller frame laterally in either direction by utilizing the power for driving the tine shaft of the tiller unit.

Abstract: A tractor having a frame supported by ground-engaging drive wheels, a tool bar carried by the tractor and on which various implements may be mounted, the tool bar being universally mounted on the frame whereby the implement may be raised above or lowered to the ground, and can follow the contour of the ground, a power unit also mounted on the tool bar so as to have a direct driving connection to the implement not affected by the universal "floating" movement of the implement and tool bar, and a driving connection between the power unit and the drive wheels, of a type not affected by the relative movability of the tool bar and tractor frame, in order that both the implement and the tractor may be driven by a single power unit. Mechanism is also provided for pivoting the tool bar to elevate the implement above the ground when desired, for supporting the tool bar while implements are changed, and for holding the implement firmly against the ground when required.
