TRANSMISSION OPERATION
QUAD SHIFT III 12 x 4 OPERATION
The transmission has three forward ranges and
one reverse range.
Within each range,
including reverse, there are four synchronized
speeds. The synchronized speeds allow for
easier shifting within each range. This
combination allows for twelve forward speeds
and four reverse speeds.
All shifting is done manually, in conjunction with
the clutch. The transmission incorporates a
shaft brake, which is designed to stop
transmission rotation when shifting between
ranges. This is activated when the range lever is
in neutral and the clutch pedal is fully
depressed.
IMPORTANT: Engage the clutch at a low throttle
setting and as light a draft load as possible to
extend clutch and synchronizer life. Do not
engage the clutch when the throttle is set higher
than 1700 RPM while under load. Raise the
implement whenever possible during shifting.
Use the decelerator pedal to bring the engine
speed down when shifting or engaging the
clutch.
All gears in the transmission are constantly in
mesh. When a range is selected, shift collars
splined to the shafts are being engaged with the
range gears.
The tractor must be at full stop
in order to shift between ranges.
The transmission bearings and gears are
pressure lubricated. The lubrication circuit
consists of a gear pump located on and driven
by the transmission, an oil cooler located in front
of the engine radiator, a filter located inside the
frame at the front of the tractor, and the oil
distribution manifold on the transmission. The
transmission case acts as a reservoir.
Should the transmission oil pressure light come
on, immediately shut down the tractor and
contact your Buhler Versatile dealer to
investigate the cause of lubrication failure.
CAUTION: KEEP THE CAB FLOOR AREA
FREE FROM DEBRIS OR OBJECTS WHICH
MAY OBSTRUCT THE OPERATION OF THE
CLUTCH PEDAL. KEEP THE PEDAL CLEAN
AND DRY TO PREVENT YOUR FOOT FROM
SLIPPING OFF THE PEDAL, CAUSING
ABRUPT ENGAGEMENT.
