5.1.2.2 Changing of gear level by means of switchgear
The switchgear is not synchronized. Changing gear level is only
possible when the vehicle is stationary or when it is coasting or
starting at low speed.
Different steps may therefore be necessary for changing gear level by
means of the switchgear. The necessary steps depend on:
• the type of actuation of the tractor’s p.t.o. shaft:
ο after the p.t.o. shaft has been switched off, the p.t.o. shaft
drive of the tractor is slowed down during coasting and
when stationary,
ο the p.t.o shaft coupling engages very fast when the p.t.o.
shaft is switched on.
• the type of remote control unit of the switchgear:
ο mecanical remote control unit via Bowden cable,
ο electrical remote control unit via control unit.
• the amount of load of the mixing auger in the mixing container:
ο empty or slightly filled mixing container,
ο fully filled mixing container.
Hereinafter, two different procedures for changing gear level by
means of the switchgear are described.
Empty or slightly filled mixing container – low amount of load of mixing auger
1. Switch off the tractor’s p.t.o. shaft.
2. Use the switchgear to change the gear level via the mechanical /
electrical remote control unit.
3. Switch on the p.t.o. shaft of the tractor again.
→ During restarting, changing gear level is initiated in the
switchgear.
Fully filled mixing container – high amount of load of mixing auger
1. Switch off the tractor’s p.t.o. shaft.
2. Prepare changing of gear level:
• Turn off the tractor engine if the p.t.o. shaft drive of your
tractor is slowed down while coasting or when stationary
after the p.t.o. shaft has been switched off.
→ In this state, the p.t.o. shaft is freely movable.
• Select the function "Switched-off p.t.o. shaft freely movable
with the tractor engine running" at your tractor if your tractor
is equipped with this function.
3. Use the switchgear to change the gear level via the mechanical /
electrical remote control unit.
4. Switch on the p.t.o. shaft of the tractor again.
→ During restarting, changing gear level is initiated in the
switchgear.
