SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
2--65
TRANSMISSION OPERATION
Your tractor may be fitted with one of three
transmission options dependent on country and
specification.
12x12SynchroCommand
This transmission offers 12 forward and reverse
synchromesh gears selected by two shift levers
conveniently placed to the right of the driver . The
forward and reverse synchronised shuttle is
operated by a lever to the left of the steering column.
24x24DualCommand
Operating in a similar manner to the 12 x 12, Dual
Command offers the additional benefit of a
hydraulically engaged underdrive for each of the
basic 12 gears. This provides 24 forward and reverse
ratios. Underdrive may be engaged on the move
without depressing the clutch pedal. A clutchless
shuttle function is also featured on the Dual
Command transmission.
16 x 16 (17 x 16) Electro Command
The Electro Command transmission has 4
powershift gears and four range gears providing 16
forward and reverse ratios. On 50 Km/h models, an
additional gear provides 17 forward ratios. When
operated simultaneously, the powershift and range
change buttons will provide clutchless changes on
the move through ratios 1--8 and 9--16 (17).
Ground Speeds
Ground speeds are displayed in the LCD on the
left-hand side of the instrument panel. However, as
a guide, ground speed charts for specific tyre sizes
are provided at the end of each transmission section.
If the rear tyres of your tractor are of a different size
to those shown in the charts, it may be necessary to
re--calibrate the speedometer as previously
described.
