A telescopic shaft assembly for torque transmission in agricultural implements includes a first and a second profiled shaft arranged in torque transmitting engagement with each other with a pair of telescopic tubular tie anchors being releasably attached one with each of the profiled shafts, the tie anchors being joined together so as to be length adjustable relatively nonrotatable by a connecting mechanism which includes a pair of axially extending slots formed in one of the tie anchors and a transversely extending bolt formed in the other which is engageable within the slots, each of the tie anchors being attached, respectively, to one of the profiled shafts by spring actuated releasable engaging devices with the engaging device connecting the innermost of the two tubular tie anchors with one of the profiled shafts enabling disengagement thereof with a lower disengaging force than the other of the engaging devices. |
