1. A method for controlling a slippage of a drivetrain including a prime mover having an output shaft, a transmission having an input connected to the output shaft of the prime mover and an output, a forward-reverse clutch arrangement having an input connected to the output of the transmission and an output, the forward-reverse clutch arrangement including a clutch having a controllable slippage level between its input and output, the method comprising:
determining a usable torque of the prime mover; and
controlling the clutch so as to allow the usable torque to pass therethrough and to cause the clutch to slip should a torque between the input and output of the clutch be greater than the usable torque.
