摘要： A frame structure of a working vehicle for attaching working implements includes front axle frames, side frames for attaching a front loader, and rear reinforcing members. The front axle frames extend forwardly and substantially parallel to each other on opposite sides of the working vehicle. The front axle frames are removably attached to an engine of the working vehicle. The side frames for attaching a front loader project laterally outwardly of the working vehicle for securing the front loader to distal ends thereof. The side frames are removably secured to the front axle frames through mounting plates, respectively. Each of the rear reinforcing members is supported at a forward end thereof by a bracket of one of the side frames, and at a rear end by a vehicle body. Each rear reinforcing member has a connector for supporting a safety frame.

摘要： A tenon-and-mortise coupler for releasably connecting any type of work implement to the front chassis of any conventional tractor. The tenon part defines an open frame, fixedly secured at its rear end to the front bottom of the tractor chassis, and tapered at its front end. The mortise part defines a hollow tapered casing, fixedly secured at its small end to the bracket assembly of the work implement and frictionally engageable by the tenon tapered end at its opposite large open end or mouth. A manually-operated lever is transversely mounted in the tenon part and defines an intermediate offset section carrying a longitudinally-extending latch bar, which is guided for combined longitudinal and vertical movement between a forward and lowered retracted position and a rearward and upper latching position. The tenon-and-mortise parts are first assembled with the latch bar in retracted position. Then the lever is rotated to bring the latch bar in latching position in which it engages the rear end of a slot made in the top wall of the mortise part. A compression spring is located between the lever and the latch bar to constantly bias the latch bar against the rear end of the slot in order to prevent any play between the tenon and mortise parts.
摘要翻译：一种榫头连接器，用于将任何类型的工作装置可释放地连接到任何常规拖拉机的前机架上。榫头部分限定了开放式框架，其后端固定在拖拉机底盘的前端，并在其前端呈锥形。榫眼部分限定了一个中空的锥形外壳，它的小端固定在工件的支架组件上，并在其相对的大开口端或嘴部可由榫头锥形端部摩擦接合。手动操作的杆横向地安装在榫头部分中，并且限定了一个中间偏移部分，该中间偏移部分承载纵向延伸的闩锁杆，该闩锁杆被引导用于在向前和向下缩回位置与后部和上部闩锁位置之间的纵向和纵向运动。首先将榫眼部件与闩锁杆组装在缩回位置。然后杠杆被转动以使闩锁杆处于锁定位置，在该位置中，闩锁接合在榫眼部分的顶壁中形成的狭槽的后端。压缩弹簧位于杠杆和闩锁杆之间，以将闩锁杆恒定地抵靠槽的后端，以防止榫头和榫眼部件之间发生任何打击。

摘要： Removable lifting devices for tractors having horizontal front wheel axles which pivot relative to the contour of the ground, one device having tubes pivotably connected on each side of the tractor frame which rotatably and pivotably receive further tubes connected by a hinged structure to the tractor's forward axle and which tend forwardly thereof to be interconnected across the front of the tractor. The connecting hinged structure permits pivotable movement of the tube relative to the axle about substantially horizontal axes parallel and perpendicular to the longitudinal axis of the tractor. The front structure connecting the tube portions extending forwardly from the axle includes a hydraulically operated three-point lifting device wherein hydraulic cylinders are disposed within a quadrangular arrangement of pivotable arms including the lower of the three-point lifting device's links. A power take-off from the rear of the tractor is connected through a gear transmission and appropriate linkage supported under the tractor, including universal joints, to extend forwardly of the tractor for optional connection to a machine or tool connected to the lifting device. In a further embodiment, the front support for the lifting device is rigidly connected to the front axle on both sides of the tractor. Torque generated by the load of the lifting device is compensated for by hydraulic cylinders which are disposed horizontally to connect the tractor's frame and upward extensions which are rigidly connected to the lifting device's front supporting beam and via same to the front axle. Such extensions are maintained in a relative vertical position by the hydraulic cylinders whereby twisting of the front axle is prevented.

摘要： A front mounted ground supported tractor attachment, steerable with and pushed by the tractor, includes a portable frame supported on caster wheels and a drive linkage connected between the frame and tractor. The drive linkage is connected to the tractor for pivotal movement about a transverse axis and the frame is connected to the drive linkage by a swivel connection for pivotal movement about a longitudinal axis relative to the tractor. In one embodiment, the drive linkage engages the frame for transmitting the pushing force of the tractor to the frame substantially independently of the swivel connection and the caster wheels allow the frame to turn with the tractor as it is steered in the usual manner. Wear plates are carried on the engaged surfaces of the frame and drive linkage.
