ABSTRACT:
A tractor hitch engageable and disengageable by an operator without leaving a tractor seat includes an upwardly and inwardly tapering cam (A) carried by a tractor at three-point hitch locations for engagement between inwardly extending marginal guides (C) integral with a complementary substantially wedge shaped cam follower (B) carried by an implement. The method includes positioning the cam below the cam follower and then lifting the cam by raising hydraulic lift arms (D) carried by the tractor exerting a guiding action between the cam and the cam follower bringing them into interlocking relation for thereafter automatically engaging a latch (E) dislodgement of the cam from the cam follower as during transport of the implement may be avoided.
