<p>The automatic attachment for implements to a tractor consists of two forks (13) which open downwards and rest against a coupling bar (7) fixed to the shafts (1) of the tractor. The coupling bar (7) incorporates truncated cone shaped flanges (11) for centring it in relation to the forks (13). One of the surfaces of the forks has hinged to it on an axle, a locking device with spring. One of the surfaces facing the locking device and the form (13) has two marks situated equidistantly from the axle of the locking piece. The other surface has a ball forced into the bottom of the recess mark.</p> |
