Daily Inspection
1.
Always set the parking brake, shut off the tractor
engine, remove the ignition key, and ensure all
moving parts have stopped before checking
mower deck or blade condition, or attempting
any repair or adjustment.
Park the power unit on a level surface, with the
engine shut off and all fl uids cold.
2. Perform a visual inspection of the power unit.
Look for loose or missing hardware, damaged
components, or signs of wear. Inspect hydraulic
hoses, hydraulic fi ttings, and fuel lines to ensure
tight, leak free connections.
3. Inspect power unit belts for wear. Belts should
be in good condition. Replace if necessary.
4. Check the power unit’s engine oil, hydraulic oil,
cooling system, tire pressure, and fuel level. Add
fl uid or service system as required.
5. Refer to the power unit operator’s manual. Test
the power unit’s operator safety interlock system.
Starting the Engine
The 3200 is equipped with an interlock system for
your safety. The following procedure is to be fol-
lowed to start the power unit.
1. The interlock system requires the “Selector
Lever” to be in the park position, the S.D.L.A.
lever to be in the neutral position, and the PTO
switch to be turned off.
2. Move the throttle forward approximately 1/4 of
its travel.
3. Turn key clockwise to the on or run position. The
3200’s engine uses glow plugs to preheat the
combustion chamber. The blue glow plug indica-
tor light will come on indicating the glow plugs
are preheating. When the glow plug indicator
light goes out, the engine is ready to start, and
must be started within a few seconds or glow
plug preheating cycle may need repeated. No
preheat is required when the engine is at operat-
ing temperature.
4. Turn the key to the start position and hold to
engage starter. Release key when engine starts.
Note: if engine fails to start, refer to the trouble-
shooting section.
5. The engine and hydraulic oil must be warmed to
operating temperature before operations. Allow
the unit to run at approximately 1,800 RPM until
the hydraulic fi lter is warm to touch. The fi lter is
located under the control dash panel.
Allow time for the hydraulic oil to circulate before
the power unit is operated. Severe damage could
result to the hydraulic system if adequate warm
up is not allowed. Warm up time is increased in
colder weather.
Forward and Reverse
1. Verify that the intended path is safe and free
from obstacles. When safe to move, begin by
moving the selector lever into either the neutral
assist position or the easy shift position.
2. Power unit movement is controlled by moving the
S.D.L.A. lever in the desired direction of travel.
Push the S.D.L.A. lever forward to move power
unit in the forward direction, or pull the S.D.L.A.
lever backward to make the power unit move in the
reverse direction. Changing the amount the lever is
moved instantly changes the ground speed of the
power unit. Moving the lever 1/2 of the stroke will
result in approximately 1/2 of the maximum ground
speed. Moving the lever to the end of the stroke
will result in maximum ground speed.
