The function of automatic deactivation of the clutch of PTO shaft means that when the PTO shaft is activated
and the arms of the rear three-point hinge are lifted, the clutch of the rear PTO shaft is automatically
deactivated and the shaft is stopped; when the arms of the rear three-point hinge are lowered again, the
clutch of the rear PTO shaft is automatically activated and the shaft starts rotating provided that the driving
direction is engaged with the return lever and the travelling speed of the tractor is 0.3 km/h at least.

performed by pressing the button (1) for at least one second. When the button (1) is released, it returns into
its original position. Further pressing of the button (1) causes deactivation of this function.
