Abstract
A coupling device for making a driving connection between a tractor power take-off shaft and a transmission shaft on an implement towed by the tractor has a coupling hub drivingly mounted on the power take-off shaft and a coupling drum coaxially surrounding the coupling hub and substantially fixed with respect to the tractor. A coupling sleeve on a power transmission shaft is detachably connected to the coupling hub by a quick-release fastener means which includes a spring-biased locking ring. A release lever is pivotally mounted on a fixed pivot on the drum and an actuating lever is pivotally connected to the release lever spaced from the fixed pivot. Pivotal movement of the actuating lever will pivot the release lever about its fixed pivot so that the release lever engages the locking ring to release the fastener means and thereby disengaging the sleeve from the hub. Further pivotal movement of the actuating lever causes the actuating lever to pivot about a stop on the drum such that the actuating lever engages a stop on the sleeve to push the disengaged sleeve from the hub.
