The end of eitherlink may move independently on theheight of the other link.LIMITING LINKSThe limiting links (1) enable side swingsof the lower links.The left and right limiting links can be adjustedby turning of the link tube, see thearrow.Both limiting links shall always bemounted on the tractor.21

HITCHESE459∗LOWER LINKS WITH TELESCOPICTERMINALSThe lower links of the hitch are equippedwith semi-automatic telescopic terminalsCBM that facilitate hitching of the implementto the tractor. After pulling out thelocking pins (1) slide out the terminals(2). These terminals then can be fastenedto the fixing pins of the carried implement.After hitching of the carried implement,release arms of the hydraulic equipment.By lowering of the arms and reversing ofthe tractor backward the terminals (2)slide into the links and lock themselvesautomatically in their working position usingthe locking pins (1).Check always position of thetelescopic terminals, see Fig. (3).22E460∗LOWER LINKS WITH HOOKS CBMThe lower (3) and upper (4) links of thehitch are fitted with hooks CBM.First the implement shall be fitted withhitching balls CBM (1) and the distancebetween the lower links (3) of the hitchshall be adjusted by limiting links.During reversing and lifting of the 3-pointhitch its lower links (3) are connected tothe implement and then the driver connectsthe upper link (4) of the 3-pointhitch from his cab.For disconnection of the implementunlock the hooks, using the control wires(2) lift the upper link (4) and by loweringof the 3-point hitch disconnect the lowerlinks (3).

HITCHES∗FRONT 3-POINT HITCHIt is designed for hitching of front-carriedagricultural machines and implementacc. to ISO 8759-2.When transporting a carried implementit is always necessary tolock the hitch in its lifted positionusing hydraulic valves that areinstalled on the left side of thetractor, above the front axle.This hydraulic locking is recommendedeven in case that no implement ishitched in the 3-point hitch.E461 H462 E463CONTROL OF FRONT 3-POINT HITCHThe hitch is equipped with two singleactinghydraulic cylinders supplied with oilfrom the additional distributor of hydraulicpressure.
