6.3 LOW / HIGH SPEED ADJUSTMENT
The LOW / HIGH speed linkage should be adjusted
whenever the lever will not allow the mower to change
speeds between LOW and HIGH range. If the following
procedures do not allow you to change speeds properly,
contact your Scag dealer for further adjustments.
1. Position a floor jack under the rear of the machine.
Raise the machine and support it to prevent it
from falling. Block the caster wheels to prevent the
machine from moving.
2. Position the speed control lever in LOW range.
3. Loosen the jam nut and remove the cotter pin
securing the speed control linkage to the speed
control rod. See Figure 6-4.
4. Adjust the speed control linkage until speed control
arm on the RH axle is against the LOW range stop.
See Figure 6-4.
5. Repeat steps for the LH axle.

WARNING
Before removing any guards, shut the engine off
and remove the ignition key.
All drive belts are spring loaded and self-tensioning,
however after the first 2, 4, 8 and 10 hours of operation,
the belts should be checked for proper alignment and
wear. Thereafter, check the belts after every 40 hours of
operation or weekly, whichever occurs first.
WARNING
If the pump drive belt fails, steering control will be
lost which could result in serious injury or death.
Replace the pump drive belt as needed or every
400 hours / 2 years, whichever occurs first.
6.6 BELT ALIGNMENT
Belt alignment is important for proper performance of
your Scag mower. If you experience frequent belt wear
or breakage, see your authorized Scag service center for
belt adjustment.
6.7 CUTTER DECK ADJUSTMENTS
Cutter deck level, pitch and height are set at the factory.
However, if these adjustments should ever need to be
made, the following procedures will aid in obtaining the
proper cutter deck adjustment.
- NOTE -
Before proceeding with the cutter deck adjustments,
be sure that all tires are properly inflated.
