Figure 2.23.1 – Control of the transmission hydraulic system pump drive
Control lever 1 (figure 2.23.1) of the transmission hydraulic system pump drive can have
two fixed positions:
position I – “Pump drive on” (normal operating position) – lever 1 is turned contraclockwise
(when you look at the gearbox from the tractor left side) in relation to center pin 3 until the
lower edge of the groove in lever 1 stops and fixed with bolt 2.
