Operating On Slopes
Maximum angle of operation for the engines in
the 4500 power units*.
• Vanguard Model 54: 20° continuous, 30° intermittent^
• Kawasaki FD851D: 30° continuous
• Kubota WG972-GL: 20° continuous, 30° intermittent^
• Kubota D902: 20° continuous, 30° intermittent^
*Attachments, accessories, and tire confi guration
may reduce the 4500 power unit’s maximum angle
of operation. Refer to applicable operator’s manuals
for maximum angle of operation of the equipment.
^Intermittent: The engine may operate between
20° and 30° for up to 10 minutes. If 10 minutes is
reached, the engine must be returned to 20° or less
to assure proper oil lubrication. After returning to 20°
or less, the intermittent cycle can be repeated.
WARNING
AVOID PERSONAL INJURY!
• Operation on slopes decreases power unit
stability and increases the potential for unex-
pected diffi culties. Only experienced operators
should operate the power unit on slopes and
extra caution should be exercised.
• Use low range when operating on slopes
greater than 15 degrees.
• Never shift between high and low range while
on a slope. Always move the machine to level
ground and place the selector lever in park
before shifting range.
• Avoid uneven, loose, or wet terrain.
• Stay clear of drop-offs, holes, ditches, rocks,
or objects that could cause a sudden and/or
unexpected force on the power unit.
• Make slow and cautious starts, stops, and turns.
• Do not exceed the maximum degree of opera-
tion. Refer to illustrations.
• Turn downhill when possible and/or reduce
the degree of turns.
• Assure a suffi cient supply of fuel for continu-
ous operation. A minimum of one-half tank of
fuel is recommended.
• Failure to follow items listed or to use com-
mon sense while operating on slopes can
result in injury or death. Always operate on
slopes with caution.
Maintain suffi cient fuel in tank to ensure continuous
operation.
Cease operation if power unit stability is question-
able, or if the operator is uncomfortable or unsure
of continuing safely.
Attachments can affect the stability of the power unit.
Each attachment will affect the power unit differently.
Increase the amount of weight being transferred to
the power unit from the attachment while operating
on slopes. Refer to Weight Transfer section.
Always operate carefully and in a manner that does
not compromise safety.
Always keep the roll bar in the upright, locked position
and fasten yourself securely with the seat belt!
Refer to following illustrations for power unit capabil-
ity with different equipment options.

Towing Or Pushing The Power Unit
I
Attention
Avoid damage to your power unit! Before tow-
ing, read and understand the information below.
Severe damage will occur to unit if proper tow-
ing procedure is not followed.
CAUTION
Failure to place the transaxles in neutral when tow-
ing or pushing the power unit may result in damage
to the power unit drivetrain.
f the power unit needs to be moved without the
engine running, it is important to remember to place
the transaxles in neutral by shifting the high/low range
shift handle to the middle of the shift stroke. With the
transaxles in neutral and the parking brake disen-
gaged, the power unit can freewheel. Use extreme
caution when towing or pushing the power unit; steer-
ing may not function. Do not exceed 5 mph (8 km/h).
