3. If the machine pulls to one side, stop the mower
by placing the steering control levers in the
neutral position. Using a wrench, turn the tracking
adjustment nut on the slower side counter clockwise
until the machine tracks straight.
4. Bring the steering control levers back to the neutral
lock position and check to see that the machine
does not creep forward on the adjusted wheel.
5. If the machine creeps in neutral, you have moved
out of the neutral band and will have to turn the
tracking adjustment nut clockwise until the machine
does not creep.
6. Repeat steps 1 and 2. If the machine continues
to pull to one side, stop the mower by placing
the steering control levers in the neutral position.
Turn the tracking adjustment nut on the faster side
clockwise until the machine tracks straight.
7. If tracking cannot be acheived, contact your Scag
servicing dealer.
6.5 THROTTLE CONTROL AND CHOKE
ADJUSTMENTS
These adjustments must be performed by your Scag
dealer to ensure proper and efficient running of the engine.
Should either need adjustment, contact your authorized
Scag service center.
6.6 BELT ADJUSTMENT
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.
6.7 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.
6.8 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.
Before proceeding with the cutter deck adjustments,
be sure that all tires are properly inflated.
CUTTER DECK LEVEL
The cutter deck should be level from side-to-side for
proper cutting performance. To check for level, be sure
that the mower is on a flat, level surface, the tires are
properly inflated and the cutter deck is set at the most
common cutting height that you will use. On the RH side
of the machine, check the distance from the top of the
cutter deck to the floor. Next check the distance from the
top of the cutter deck to the floor on the LH side of the
machine. Both measurements should be the same. If the
two measurements are different, the cutter deck level must
be adjusted as follows:
1. If the cutter deck is lower on one side, loosen the
elastic stop nuts securing the hanger chains to the
cutter deck on the front and rear of the lower side.
See Figure 6-5.
