A power-split axle drive for an agricultural vehicle including a first additional drive element, a first vehicle axle, a second vehicle axle, and a primary drive element for providing a torque which via a first shaft is able to be transmitted to a primary transmission. The primary transmission is connected to the second vehicle axle, and at least the second vehicle axle via the primary transmission is able to be driven by the torque of the primary drive element. The power-split axle drive includes a power-splitting transmission. The power-splitting transmission via a first gear set is connected to the second vehicle axle and the primary transmission and via a second shaft is connected to the first vehicle axle. The first additional drive element via a first switching element is able to be connected to the power-splitting transmission.

A method is provided for controlling the operation of an attachment that is coupled to a tractor via a top link and two bottom links of a powerlift. The method includes selecting a point of action from at least one of a pull point as a geometric intersection of imaginary extensions of both bottom links and a pole point as a geometric intersection of imaginary extensions of the top link and a bottom link. The method also includes determining a position of the selected point of action, and signaling the determined position of the point of action by a display unit or adjusting the determined position depending on a comparison with a setpoint setting.

A coupling device for attaching a power lift of a tractor to an attachment includes a link mounting region having coupling units for the articulation of an upper link and two lower links of the power lift, and an apparatus mounting region for fixing the attachment. A coupling unit assigned to the upper link is movable in a translatory manner in a vertical direction running perpendicular to a transverse direction. The coupling units are movably disposed on a device base of the coupling device, and the coupling units assigned to the two lower links are movable in a translatory manner in the transverse direction.

A ballasting device for an agricultural vehicle includes a ballasting body, a first ballasting arm, and a second ballasting arm. The first ballasting arm is pivotally mounted on the ballasting body about a first bearing axis on one end and a first ballasting weight is arranged at the other end thereof. The second ballasting arm is pivotally mounted on the ballasting body about a second bearing axis at one end and a second ballasting weight is arranged at the other end thereof. The ballasting device includes a receiving device for receiving the ballasting device via a three-point hitch device of the agricultural vehicle. The first ballasting weight is adjustable by the first ballasting arm and the second ballasting weight is adjustable by the second ballasting arm.

An additional wheel weight for a utility vehicle includes a weight plate and a retention member configured to be fitted to a wheel and on which the weight plate is guided in a longitudinally axial manner. A clamping lever closure is disposed between the weight plate and retention member. A first assembly element of the clamping lever closure is coupled to the retention member, a second assembly element of the clamping lever closure engages the weight plate in a longitudinally axial manner, and a lever mechanism is disposed between the first and second assembly elements. The lever mechanism includes a clamping element being releasably secured to the first assembly element and an actuation lever being articulated between the second assembly element and the clamping element.
