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
Refer to Figure 3-6:
The spindle belt tension remains constant by means of a
tension idler and spring.
The spring tension should be such that the belt does not
slip under normal operating load conditions, assuming the
belt is not excessively worn or damaged. As belt stretches
and wears in, adjustment may become necessary. To
increase belt tension, move the spring chain one (or more)
link(s) at the anchor bracket (Figure 3-6). Installed spring
length should be 7 1/2" + or - 3/8" originally with
adjustments of 5/8" per chain link.
Engine RPM Setting
The Razor Z 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. Raise deck and place 3” of blocking under all 4
corners of the deck. This will set the cutting height at
3 1/4”. Refer to Figure 3-7.
