When operating with RPTO in a synchronous mode, it is necessary to take into account
the following:
- PTO shaft end extension rotates only while tractor movement;
- operating tractor speed in structure of machine-tractor unit shall not exceed 8 km/h;
- the direction of rotation of PTO shaft end extension (if you look at the butt end of PTO
shaft end extension) is different as the tractor moves forwards and backwards: at forward
motion – it rotates clockwise, at backward motion – counterclockwise.
