Trol - New Holland T4.75F Operator's Manual

Transmission with gear reducer, electrohydraulic reversing mechanism
and HI-LO control
30 km/h (18.6 mph) - 40 km/h (24.9 mph) - 32 FWD + 16 REV
WARNING
Unexpected machine movement!
With the engine running and only the gear
lever in neutral, the machine can engage and
move suddenly if someone accidentally op-
erates this lever. Place all levers in neutral,
disengage the Power Take-Off (PTO), lower
any implements, set the handbrake and park-
ing brake before exiting the machine.
Failure to comply could result in death or se-
rious injury.
The operation of the gear levers, range gear and electro-
hydraulic shuttle is the same as that previously described
on the "Transmission with gearbox and shuttle" pages for
the 16FWD+16REV version
The gear lever (1) in fig. 1 is moreover equipped with
control buttons for the functions HI− LO (2) and (3), that
enable doubling the forward gear ratios, for a total of 32
available gears. It is possible to pass from position HI
(2) to position LO (3) by pressing the two buttons without
using the clutch pedals.
With the shuttle lever (1) fig. 2 in the reverse position
(backwards), position (HI) is automatically excluded, thus
reducing the number of available reverse gears to 16. To
reverse the direction of travel, lift and move the lever for-
wards or backwards. Drive direction can be changed with-
out pressing down the clutch pedal.
Operation
With the tractor moving it is possible to invert the drive
direction without stopping and without pressing down the
clutch pedal.
When driving forward in range HI and you move the shut-
tle lever (1) fig. 2 into reverse position, when the tractor
begins to reverse, the indicator (1) fig. 3 will illuminate to
signal the move into range LO.
When you move the shuttle lever (1) fig. 2 back into the
forward position, the indicator will illuminate (1) and the
indicator (2) fig. 3 will start flashing to indicate the auto-
matic passage from range LO to range HI set previously.
On completing the change, the indicator (1) will turn off,
while the indicator (2) will stay on to signal that range HI
is selected.
NOTE: The indicator (1) fig. 3 is present only in configu-
rations with an analogue instrument cluster.
