摘要： An agricultural implement has a forwardly extending tongue connectible to the drawbar of a towing tractor and includes a fore and aft drive shaft that is disposed above the tongue and adapted to be connected to the PTO output shaft of the tractor by a PTO hookup assembly that includes front and rear universal joints respectively connectible to the implement drive shaft. When the hookup assembly is not connected to the tractor, the front end of the assembly is supported on the implement by a support that includes a support member swingably mounted on the implement tongue for shifting between a folded storage position and an upright operative position. A hook-like retainer member is mounted on the upper end of the support member and is shiftable between a generally upright position, wherein it is capable of receiving the central body portion of the hookup assembly, and a canted position wherein the hookup assembly cannot be withdrawn from the retainer member so that the hookup assembly is locked to the support.
摘要翻译：农具具有可连接到牵引拖拉机的牵引杆的向前延伸的舌头，并且包括前后驱动轴，该前后驱动轴设置在榫舌上方并适于通过PTO连接组件连接到拖拉机的PTO输出轴，该组合包括前后万向节分别可连接到工具驱动轴上。当联接组件未连接到拖拉机时，组件的前端通过支撑件支撑在工具上，该支撑件包括可摆动地安装在工具舌上的支撑构件，用于在折叠的存放位置和直立操作位置之间移动。钩形保持构件安装在支撑构件的上端上，并且可在大体上直立的位置之间移动，其中其能够容纳连接组件的中心主体部分，以及倾斜位置，其中连接组件不能从保持器构件中拉出，使得连接组件被锁定到支撑件上。
