Device for coupling attachment tools with

Three-point hitch on tractors. , _;

The invention relates to a device for coupling Attachment tools with triangular arrangement Coupling points that are attached to the three-point linkage of the Tractor is attached "

The coupling of an attachment to the handlebars .- ■. ' of the three-point force lover is only through with almost all devices several persons possible, whereby the youthfulness.Eiit der Increase in size of the Aiiba.u tool.

"There are already known coupling frames that are attached to the handlebars of the '."Raftlie'b-jps and consist of a rigid U- or triangular construction made of profile steel.

The upper coupling point or the. two lower coupling points are to facilitate the coupling process and to compensate for differences in the vertical distance of the devices e -: -, Bolt fixed or arranged so that it can be swiveled about horizontal axes of rotation. '"-' .." ■ ■ '. . . . ",

The locking and unlocking of the device bolts wi. around with the help of a concrete lever system at several or only at individual coupling points.

The jachteil of the known coupling devices is ■ -darin- that the distance between the two lower ..horizontale Kupplunyspunkte can not be changed continuously and thus the Anv / öndungsbereichö only some types of attachments-loading -.- ■ restricts remains. ¹ ,, since the distance between the implement bolts according to the international IT standard fluctuates within a very wide range of tolerances

ii of the invention is through the inventive solution to eliminate the above-mentioned deficiencies-and a inclusion of the A wide variety of counterparts of attachment implements with one on the three-wheel power lift of a tractor * -
