Engine RPM Setting
The Razor Pro is designed so that the engine will run at
3600 rpm static pump load only. At this speed the
hydraulic pumps are running at their maximum rated
speed.
Deck Leveling and Height Adjustment
The mower deck has three areas that may need to be
checked and adjusted periodically. Before considering
any mower deck leveling adjustments, check that the tire
air pressure is within the specified range.
!
WARNING!
Stop engine. Make sure deck clutch switch is in the down (OFF)
position. Place control levers in the brake position before
leaving machine.
Deck Level Adjustments
Leveling the deck must be done in the following manner
and order:
1.
Check tire pressures to make certain they are properly
inflated before starting to level deck.
2.
Park the unit on a flat surface.
3.
Refer to Figure 3-15. Raise deck and place 3” of
blocking under all 4 corners of the deck. This will set
the cutting height at 3 1/4”.

4.
Refer to Figure 3-16. Set cutting height at 3 1/4” on the
height indicator by placing the height adjusting stop in
the 3” hole, and turning the height stop so that the flat
side is against the stop handle.
5.
Clamp the height adjusting stop against the stop
handle. This will assure that the height will not move
during the setting process. Otherwise, spring
pressure from the deck lift springs will tend to pull the
stop away from the handle.

IMPORTANT: Refer to Figure 3-14. Do not over
tension the spring to compensate for a badly worn belt
or pulley.
