Abstract

A tractor implement attaching hitch mechanism of the three-point type that utilizes a hydraulic actuator for readily adjusting the attaching mechanism out of a vertical plane, whereby the remotely controlled latches may be activated for attaching the implement to the tractor. The hitch mechanism comprises a frame including a pair of depending legs interconnected by a horizontal support member. The support member and one of the legs include brackets which are connected to two draft links of the tractor, and the other leg is connected to the other draft link by a link member which is pivotally connected to the leg and the draft link. The hydraulic actuator is carried by the support member and connected to the link member for pivoting the link member so as to vertically move the leg to vary the plane of the hitch mechanism relative to the tractor.

Dependent claims

An adjustable quick-latch hitch for tractors providing three-point draft link connections comprising

a. a hitch attachment comprising a rigid frame including a pair of depending legs interconnected by a substantially horizontal support member,
b. said support member and one of said legs providing connecting brackets adapted to be connected to corresponding draft links of the tractor for connecting said attachment thereto,
c. a link member pivotally connected at one end to said other of said legs and at its opposite end to a draft link of the tractor,
d. pivoting means carried by said support member and connected to said link member for pivoting the same relative to its connection to said other of said legs and to the draft link of the tractor so as to vertically move said other of said legs to vary the plane of said hitch attachment relative to the tractor, and
e. means provided by each of said legs for releasably connecting said hitch attachment to an implement to be pulled thereby.
