Abstract
Arrangement for coupling an implement to a hydraulically operated coupling device on a tractor, said arrangement comprising a male coupling frame attached to the tractor and cooperating with a female coupling frame attached to the implement, the arrangement in coupled position providing a power transmitting union. Power transmission is effected via an upper union where the coupling beams of the female frame straddle the corresponding guide beams of the male frame, and by two lower coupling devices consisting of catch hooks on the male frame and interacting coupling hooks on the female frame. The coupling members are locked and released by a separate spring-loaded latch provided with an indicating lever to which an operating mechanism has been attached.
