ADJUSTMENTS
PARKING BRAKE
Minor brake adjustments can be made by loosening
the top nut on both brake cables (see Figure 4).
Back the nuts off approximately 1/4". While pulling
one cable downward, tighten the bottom nut on the
cable until it touches the bottom of the brake cable
mount. Tighten both the top and bottom nuts to
lock the cable in place. Repeat the above steps for
the second brake cable. Make sure that both
cables are adjusted evenly so that the brakes do not
cause the mower to pull to the left or right.
-NOTE-
This is a minor brake adjustment. If the
brakes do not function properly after this
adjustment, see your Scag Service Dealer
before operating your mower.
NEUTRAL ADJUSTMENT
1. Set the engine deck up on jack stands so the wheels
are free to rotate.
2. Block the caster wheels to prevent an accident
should the machine fall off the jack stands.
3. Start the engine and determine if the drive wheels
rotate.
If the drive wheels consistently rotate when foot
pedal control is in neutral, go to step 4.
If the drive wheels inconsistently rotate, i.e. drive
wheels sometimes rotate and sometimes do not
when foot pedal is not depressed, then check
neutral adjustment bolt for "zero free play" in neutral
control spring.
-NOTE-
If there is free play in the foot pedal have your
SCAG servicing dealer inspect the machine and
repair it as needed.
4. If the drive wheels rotate in the forward travel
direction, turn the adjustment bolt clockwise until the
tire rotation stops. If the drive wheels rotate in the
backward travel direction, turn the adjustment bolt
counter-clockwise until the tire rotation stops (See
Figure 5).
