Abstract
A drive shaft assembly for providing a drive connection between the power take-off shaft of a tractor and an agricultural implement is formed in two drive shaft parts with one of the parts which is attached to the tractor joint being formed with a coupling sleeve and with the other drive shaft part which is attached to the implement to be driven being formed with a coupling hub engageable and disengageable in the coupling sleeve. The other drive shaft part is also formed with a length adjusting device comprising a pair of spring-loaded telescoping tubes arranged between the coupling hub and the end of the other drive shaft part which is attached to the implement to be driven and, as a result, the disconnecting point of the drive shaft assembly is thus located between the joint which is associated with the tractor and the length adjusting device of the other drive shaft part thereby to facilitate engagement and disengagement of the drive shaft assembly.
