ABSTRACT:
A drive shaft (30), adapted to be connected to the power takeoff shaft (14) of a tractor, comprises a longitudinally extensible shaft (33) including a tapered head (34) that is movable into and out of meshing engagement with a correspondingly shaped socket (50) on the outer end portion (49) of a driven shaft (48). The driven shaft is carried by an implement (27) and includes an inner end portion (49) connected to the outer, socket equipped end portion by a universal joint (51), the inner end portion being adapted for connection to a mechanism to be driven. A coil compression spring (53), loosely encompassing the universal joint, has opposite ends engaging flanges (54,55) on the inner and outer end portions of the driven shaft to yieldingly hold the driven shaft portions in alignment. A bearing (56) for the outer end portion of the driven shaft is mounted on the implement by mechanism including a spring (60), to enable turns of the tractor and implement.
