Claim:
A device for longitudinally balancing an agricultural vehicle, in particular a tractor, the device comprising: at least one ballast carried on one of a front end of the vehicle or a rear end of the vehicle and movable longitudinally along the agricultural vehicle; a first actuating device carried on the other of the front end of the vehicle or the rear end of the vehicle, the first actuating device configured to move a load on an implement connected to the vehicle upward or downward; a sensor for detecting stress of the load on the end of the vehicle affecting a longitudinal attitude of the agricultural vehicle; and a second actuating device connected to the ballast to move the ballast longitudinally in such a way as to at least partly compensate for the stress in response to a signal from the sensor, wherein the second actuating device moves the ballast to an extended position at least partially away from one end of the vehicle to offset the load from the other end of the vehicle, and wherein the second actuating device is positioned substantially within the ballast when in a non-extended position, and a portion of the second actuating device is disposed outside of the ballast when the ballast is in the extended position.
