FOOTPEDAL CONTROLS / MOVING OFF (fig 1,2)
To move off, ensure your foot is off the pedals ‘A’ and ‘B’ then
disengage the parking brake by moving lever ‘C’ (fig 2) forward.
Now gently depress either pedal ‘A’ or ‘B’ (fig 1) to move off
forward or backward. The function of either pedal has the same
effect as the accelerator on a car except that it controls the
hydrostatic transmission and does not effect the speed of the
engine. N.B. The engine speed must be set to maximum
whenever the tractor is used. Never attempt to depress pedal ‘A’
and ‘B’ together as damage to the linkage may occur which will
not be covered by warranty.
REVERSING (fig 1)
To engage and control reversing simply take your foot off pedal
‘A’ – to avoid a rapid stop remove your foot gently. The tractor
will come to a standstill. When the tractor is stationary, depress
pedal ‘B’ to move backwards.
PARKING (fig 2)
Remove your foot from pedal ‘A’ and ‘B’ and the tractor will
come to a standstill. Now engage the park brake by simply
moving lever ‘C’ (fig 2) rearward to an upright position- you will
feel the lever lock into this position.
EMERGENCY BRAKING (fig 1,2)
In case of an emergency remove your foot from the drive pedal
simultaneously engaging park brake lever ‘C’. The tractor will
stop abruptly.
DIFFERENTIAL LOCK (fig 3)
The D18/50 is fitted with a differential lock for maximum
traction on slopes and slippery ground. The differential lock
should only be used in situations where one wheel is slipping and
the other is not. In a situation when one wheel starts to slip and
extra traction is required simply depress pedal ‘D’ (fig 3) and the
differential will lock both wheels to drive at the same speed. As
soon as the differential lock is not required release the engage
pedal ‘D’ and as soon as the wheels are rotating at the same speed
and not under load (i.e. on a slope) the lock will automatically
release.
WARNING: Do not attempt to steer the tractor
when the differential lock is engaged. Always
ensure the differential lock is released before
manoeuvring in a closed area.
HYDROSTATIC BYPASS VALVE (fig 4)
To push or freewheel the D18/50, release the park brake then
disengage the hydrostatic transmission by releasing the bypass
valve. Simply pull the bypass valve lever ‘E’ (fig 4) outward.
You will now be able to push the tractor. Reset the bypass valve
by pushing the lever in BEFORE starting the tractor.
