Hydro-Drive Belt Adjustment

The pump drive belt tension remains constant by means
of a tension idler and spring. There is no tension
adjustment of this belt.

Deck Drive Belt Adjustment

The spindle belt remains in constant tension by means of
a spring tensioned idler. The spring tension should be
adjusted so that the belt does not slip under normal
operating load conditions and may require readjusting as
the belt stretches and wears. The belt should be
replaced if it is excessively worn or damaged.

Refer to Figure 3-5 and Figure 3-6:
Check spring length to verify if belt is tensioned correctly.
Installed spring length should be 4 3/4" +or- 1/8". Vary
the spring length by adjusting the length of the eye bolt.

Excessive belt tension may lead to premature damage of
belt and drive components and is also a safety hazard to
the operator and bystanders. Not enough belt tension
may also lead to premature belt damage due to
excessive belt slippage.

Engine RPM Setting

The Razor 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 & 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 blade engagement switch is in the
down (OFF) position. Place control levers in park position
and set park lever to (ON) before leaving machine.

Deck Level Adjustments

Leveling the deck must be done in the following order:

1.

Check tire pressures to make certain they are
properly inflated before leveling deck.

2.

Park the unit on a flat surface.

Refer to Figure 3-7:

3.

Raise deck fully up.

4.

Position the blade cutting height at 3 1/4” by placing
3" high deck support blocks under the deck edge in
three locations:

a. Place two of the 3" support blocks under the deck

front edge in-line with the far left and far right blade
spindles.

b. Center the third 3" support block under the deck

back edge.
