10. To "freewheel" or move the machine around
without the engine running, turn the dump valve
levers located at the back of the pumps to the
"freewheel" positions (see Figure 1). To operate
the machine, the dump valve levers must be
returned to the closed positions.

CUTTER DECK ADJUSTMENTS
Due to the many cutting conditions that exist, it is difficult
to suggest a cutter deck setting that will work for every
lawn.  There are two adjustments that can be made on
these decks, pitch and height.
PITCH is the angle of the blades (comparing front to
rear).  A 1/4" downward pitch (front of deck down) is
recommended for best cutting performance.
CUTTER DECK BELT ADJUSTMENTS
-NOTE-
All the belts on the SWZU are spring loaded and
do not require adjustment.  Check the belts for
excessive wear or damage daily for the first week.
After the first week, check the belts monthly.
1. Remove the belt covers.
2. Inspect the belts for wear, cracking, or glazing.
Contact your Scag dealer if any unusual wear is
noted.
3. Replace the belt covers.
HEIGHT is the nominal distance the blade is off of the
ground.  This measurement is made with the blades
pointed side to side and distance is measured between
cutting tip and ground.
Changes to the cutting height can be achieved by reposi-
tioning the cutter deck.  There are eight available posi-
tions from 1" to 4-1/2" (See Figure 2).
Do not adjust the cutting height with the mower
blades rotating. Shut off the engine and remove
the ignition key. Bodily injury could occur from
the rotating blades.
WARNING:
4. Repeat the above process on the opposite side of the
cutter deck.
3. Lift or lower the deck to the desired cutting height
and reinstall the hairpins.  A deck height decal is
located on the deck mounting frame as an aid in
adjusting the deck to the desired height.
2. While holding up on the deck support handle, remove
the two hairpins from the adjusting pins on one side
of the cutter deck (See Figure 2).
1. Shut off the engine and remove the ignition key.
