8. Take measurements from the same location on all
three decks to make sure they are at the same
cutting heights.
9. Additional fine tuning adjustments may be needed
after a test mowing run.
Belt Tension
Refer to Refer to Figure 3-4:
!
CAUTION!
Belt drive system under spring tension; use care to avoid
bodily harm!
1. To check tension apply force at arrow “A” with a
tension tester and deflect the belt 1/4". The force
required to get this deflection should range from
7to10lbs.
2. To adjust belt tension, adjust eyebolt (#1), as
necessary. This adjustment will increase or decrease
tension on the spring (#2).
3. If eyebolt (#1) does not provide enough adjustment
to get the proper tension, then reconnect chain (#3)
to a different length. All chain tension must be
removed at the eyebolt nut before readjusting the
chain.
4. Excessive tension on the belt may lead to premature
failure of belt and drive components. Excessive
tension on the belt may also lead to a safety hazard
to the operator or bystanders. Not enough tension on
the belt may lead to premature failure of the belt due
to excessive slipping.

IMPORTANT: Belt tension should be checked on
new belts after approximately 20 hours of operation.
5. After making height adjustments, always replace
linch pins by inserting them into the gauge wheel
spindle pin holes from the front to keep from loosing
the pins and gauge wheels.
6. Lower the mower to the field position making sure all
fold cylinders are fully extended.
Refer to Figure 3-3:
7. Adjust front of center deck height to match height at
rear of center deck:
a. Attach jack stand to jack mount located in front of
the center gearbox channel. Make sure stand is
secured with attachment pin.
b. Screw jack out to lift front of mower deck and in to
lower deck front.
c. Place same number and thickness of c-spacers
below the spindle tube as what was placed below
the rear gauge wheel spindle tubes.
d. There is a groove in the carrier rod for adding or
removing c-spacers. Turn the c-spacer so that the
open end will slide in or off the groove as needed.
e. Remove jack stand and return it to the storage
tube located in front of the divider gearbox.
f. Place additional c-spacers above metal spindle
tubes.

IMPORTANT: Linch pins should always be inserted
into the gauge wheel spindle pin holes from the front
so that the locking clasp is flipped shut over the
spindle towards the back. Attaching the pin in this
manner will prevent vegetation from catching on the
clasp and flipping it open while traveling forward.
