1 Trailing steering axle
2 Steering cylinder
The Ackerman steering of the trailing steered
axle is thereby locked or released via the
associated tractor control unit. The trailing
steering axle is movable in the floating position.
The trailing steering axle is centred and locked
when the tractor control unit is pressurised.
Field mode
Switch the control unit to floating position.
Open the shut-off valve. This allows the trailing
steering axle to follow the tractor.
Road mode
At low travel speed the axle can also follow-up
in road mode. At higher travel speed, the axle
must be locked manually to increase driving
stability and safety. This is done by pressurising
the tractor control unit and closing the lock valve.
Manoeuvring mode
When manoeuvring, pressurise the tractor
control unit and close the lock valve.
NOTE
The trailing steering axle is centred and locked
only under pressure. If necessary, pressurise
the tractor control unit permanently until the
lock valve was closed to prevent uncontrolled
movements of the trailing steering axle!
CAUTION
Risk of accident from the machine topping
over at excessive speeds in curves e.g. at the
headland. Corner only with appropriate speed.
