Abstract

A coupling device for connecting a drive shaft in a farm implement wherein a support arm is pivotally mounted at both ends thereof with the drive shaft in order to support the drive shaft in a manner which facilitates coupling thereof with a drive source. The support arm is telescopically extendable and includes a first spring connected to apply a spring force relative to pivotal motion of the support arm and a second spring applying a spring force acting longitudinally of the telescoping support arm. One end of the support arm is mounted at a point of articulation associated with the driven end of the drive shaft and the other end of the support arm is mounted at another point of articulation which is connected through a bearing with the free end of the drive shaft at which a connection is made with a drive source.
