Abstract
The disclosure relates to a method for setting a height position of a power lift mounted on a utility vehicle and coupled to an attachment for soil cultivation. A provided base characteristic curve represents a relationship between a target height position of the power lift and a tractive force expected on the power lift. For a selected target height position, the tractive force expected by the base characteristic curve is defined as a target tractive force . Depending on the target tractive force and an actual tractive force sensed at the power lift, a resulting height position of the power lift is determined and set. The disclosure also relates to a utility vehicle having a control unit for carrying out such a method.

A method for setting a height position of a power lift mounted on a utility vehicle and coupled to an attachment for soil cultivation, the method comprising:
- providing a base characteristic curve , which represents a relationship between a target height position of the power lift and a tractive force expected on the power lift,
- expecting the tractive force for a selected target height position defined as a target tractive force by the base characteristic curve, and
- determining and setting a resulting height position of the power lift depending on the target tractive force and an actual tractive force sensed at the power lift.
A utility vehicle on which a power lift is mounted, which is coupled to an attachment for soil cultivation, comprising:
- a force sensor for sensing an actual tractive force on the power lift, and
- a control unit for setting a height position of the power lift such that
- (i) a base characteristic curve is provided, which represents a relationship between a target height position of the power lift and a tractive force expected on the power lift,
- (ii) the tractive force for a selected target height position, expected by the base characteristic curve, is defined as a target tractive force, and
- (iii) a resulting height position of the power lift is determined and set, depending on the target tractive force and the actual tractive force.
