| PURPOSE: To provide a power take-off assembly which allows rapid and easy conversion to a different operating speed. CONSTITUTION: A power take-off assembly for a working vehicle includes an output drive member which can be driven at various speeds and power levels and an output shaft for connection to the output drive member. A hollow, cylindrical breakaway drive collar 122 includes a first end having a first set of splines 126 which mesh with the corresponding splines of the output shaft, a second end having a second set of splines 124 which meshes with the corresponding splines of the output drive member, and a central neck portion 128 located between the first and second ends. The neck portion 128 is formed so that a drive collar 122 ruptures at its neck portion 128 as a result of accumulation of damage caused by torque and prevents transmission of torque to the output shaft, and so that the drive collar ruptures prior to rupture of the output shaft. A bearing assembly is fixed with respect to the vehicle and rotatably supports the output shaft. COPYRIGHT: (C)1995,JPO | ||||||

| PURPOSE: A hybrid working machine using PTO(power take off) is provided to adjust work load by moving the working machine up and down. CONSTITUTION: A hybrid working machine using PTO(power take off) comprises a generator motor(10), an electric motor(20), a hydraulic pump(30), a three-point hitch hydraulic cylinder(40), a displacement sensor(42), a speed sensor(44), and a controller(50). The generator motor is connected to a PTO shaft of a tractor working machine and maintains the torque and RPM of the PTO shaft. The electric motor generates mechanical energy. The hydraulic pump is connected to the electric motor and generates hydraulic pressure. The three-point hitch hydraulic cylinder ascends or descends a working machine through the pressure provided by the hydraulic pump. | ||||||

| A multi-coupler assembly for a work vehicle includes a first bank of fluid connectors, a second bank of fluid connectors configured to matingly engage the first bank of fluid connectors along a coupling axis, and a coupler mechanism coupled to the first bank of fluid connectors. The coupler mechanism is controllable to bring the second fluid connector bank into mating engagement with the first fluid connector bank. A breakaway feature is integrated into the coupler mechanism. The breakaway feature facilitates controlled disengagement of the first fluid connector bank from the second fluid connector bank along the coupling axis during a breakaway event, such as when an implement inadvertently detaches from the work vehicle. The breakaway feature may permit controlled disengagement of the first and second fluid connector banks without requiring movement of the coupler mechanism. | ||||||

| A drive assembly driven by a drive unit locks one or several operating units (6) of an agricultural implement (1) or of a self-propelled implement. The operating unit (6) can be locked when switching off the drive unit or upon reaction of an overload coupling (4). The drive assembly (3) has an overload coupling (4) connected to the drive unit and driven by the drive unit in one driving direction of rotation. The overload coupling (4) is also connected to the operating unit (6). The drive assembly (3) further has a brake unit (5) connected to the overload coupling (4). The brake unit (5) is intended to be arranged in the driveline between the overload coupling (4) and the operating unit (6). Actuating mechanism (10) actuates the brake unit (5) when the operating unit is running so that the operating unit is braked and locked. Thereafter, the overload coupling is disconnected. | ||||||

| A drive assembly, especially for agricultural implements with rotatingly driven masses, has a shear pin coupling (1) with a coupling hub (3) and a coupling sleeve (12) rotatable relative to the coupling hub (3). A ratchet gear (20) supported on the coupling hub (3) and rotatable relative to the coupling hub (3) and the coupling sleeve (12). All three components (3, 12, 20) are connected to one another by the head screw (26) constituting the shear pin. A ratchet (not illustrated) may engage a holding face of the ratchet gear (20). This results in the head screw (26) being sheared. As a result, the coupling sleeve (12) is disconnected from the coupling hub (3) in respect of drive. | ||||||

| A power-take-off of a utility vehicle such as an agricultural tractor has a clutch (3) and a brake (18) to retain the output shaft against rotation when the clutch is disengaged. The invention provides a means of automatically disengaging the brake to permit rotation of the output shaft for the purpose of coupling an implement thereto. In one embodiment, the clutch and brake are engaged by fluid under pressure, and are disengaged by stopping the vehicle engine and thus allowing engine generated fluid pressure to decay. | ||||||

| A curved implement tongue improves the turning characteristics of the implement, such as a mower-conditioner. The tongue is bent in the horizontal plane and incorporates a generally vertical box section at the end of the tongue. The tongue supports a driveline transmitting rotational power from a prime mover to the operative components of the mower-conditioner. The driveline incorporates a clutch assembly mounted on the input shaft of a bevel gearbox. The forward end of the input shaft is formed with a conical surface that mates with a corresponding conical hub bore formed within the clutch assembly. The end of the input shaft is formed as a truncated cone to provide a gap between the end of the shaft and the bottom of the bore and assure a proper seating of the two members. | ||||||

| A shaft construction transmits power from a vehicle to a driven mechanism located on an implement. The shaft construction includes a first shaft having a first end coupled to the driving shaft of the vehicle. A second end of the first shaft is coupled to a first end of a second shaft by a first universal joint. A second end of the second shaft is coupled to a driven shaft of the implement by a second universal joint. A positioning structure includes a first frame disposed adjacent the first universal joint and a second frame disposed adjacent the second universal joint. The first shaft is rotatably coupled to the positioning structure so that it is maintained substantially perpendicular to the first frame in the horizontal plane. The first and second frame members are connected by a pair of elongated links. Each of the links is pivotally secured at opposite ends to each of the frames. The links cross one another as they extend between the frames. This positioning structure maintains the angle between the first and second shafts substantially equal to the angle between the second shaft and the driven shaft of the implement in the horizontal plane. | ||||||

| A ground working implement comprises a frame, a rotary ground working unit supported by the frame and rotatable about a horizontal axis, a transmission for the working unit, a cover assembly covering the working unit and including a movable cover, and a holder detachably engageable with the frame and the cover to hold the cover while the cover is in contact with the ground at a position to the rear of and spaced from the peripheral portion of the working unit in contact with the ground. Thus the cover cooperates with the working unit to serve as a stand for holding the implement in its upright position. The cover is also holdable in a raised position by the holder to facilitate the maintenance of the working unit. The cover can also be shaped to have a front contact portion and a rear contact portion continuous therewith and positioned at a lower level than the front contact portion with an intermediate portion therebetween held out of contact with the ground by a space. A suspender can be provided for suspending the cover assembly from the frame, which can include a shock absorber. | ||||||

| A cultivator has soil working members on upwardly extending shafts that are driven by a transmission from the p.t.o. of a prime mover. The transmission includes a transmission shaft that drives an extension of one of the upwardly extending shafts via a speed change gear mechanism of exchangeable pinions. The pinions are located at the top of the mechanism for easy and quick access and the shaft extension is positioned in front of the transmisson shaft. The soil working members are driven through spur toothed pinions in mesh with one another and housed in a hollow frame portion of the cultivator. | ||||||
