Abstract
A tractor having a pair of parallel catch arms pivotally mounted on the rear portion of the tractor are engageable with a shield plate mounted on the implement or machine to be coupled to the tractor. The lower ends of the catch arms are pivotally mounted to a supporting bracket on the tractor and are rigidly connected by a catch plate. At least one retaining pawl is pivotally mounted on each catch arm and has a jaw opening engagable with a locking shaft. A locking element actuable by a safety linkage is pivotally mounted on the catch arm and has a curved locking surface extending eccentrically of its pivot mount for lockingly engaging the retaining pawl. The locking element is secured in position by a locking lever and the entire locking mechanism can be released only by actuation of the locking lever and the safety linkage.
