Figure 1. PTO 540/1000 r/min and PTO 540/750 r/min.
Front end of shaft (1) is connected to the coupling sleeve in
the pump drive mechanism at the rear end of the gearbox
input shaft. Shaft (1) is rotated by the pump drive shaft from
the engine flywheel. Shaft (1) front end together with the PTO
clutch drum (4) always rotate when the engine is running.
When there is no oil pressure in the PTO clutch, power is not
transmitted to the PTO shaft (2). Now the PTO brake cup
springs engage the brake which prevents upper shaft gear-
wheels from rotating

When pressurised oil acts in the PTO clutch, the clutch is en-
gaged (and the brake is released) and power is transmitted
to the PTO shaft gearwheels. When sliding coupler (3) is in the
front position, 1000 r/min PTO or 750 PTO has been en-
gaged. When the coupler is in the rear position, 540 r/min PTO
has been engaged.
Note! In the picture above the locking flange at the front end
of the PTO shaft (2) is the earlier version. Later version is illus-
trated on page 460/7. Additionally, the clutch housing has
been reinforced with a metal ring, see page 460/9.
