FOUR-WHEEL DRIVE
The shift lever for the four-wheel drive is located
on the left-hand of the seat, Figure

wheel drive(OFF).

The front wheel drive should be
used when additional traction is required while op-
erating in loose soil, wet, slippery conditions or on
slopes.
For normal operation on firm soil, level hard sur-
faces and roading the unit at high speeds, front
wheel drive should be disengaged to maximize tire
and driveline life and fuel economy.

TRANSMISSION GEARSHIFT LEVERS
The transmission main shift lever and range selec-
tor lever, are shown in Figure
18 or 19 .
A diagram showing the shift pattern is on the bezel
around the gearshift lever.
Three forward and one reverse speeds are pro-
vided for each of the three ranges. This provides a
total of 9 forward and 3 reverse speeds.
Ground speeds for the various gear ratios can be
found on page

the tractor is moving. The mechanical transmission
is not synchronized. The clutch pedal must be de-
pressed and tractor motion stopped to change gear
ratios with the main shift lever or the range shift
lever.
