DANGER
To avoid serious injury or death:
Always disconnect driveline from the tractor before servicing
the drivetrain and components powered by the drivetrain. A
person can become entangled in the drivetrain if the tractor is
started and the power take-off is engaged.
!
WARNING
To avoid serious injury or death:
•
Always follow "Tractor Shutdown Procedure" provided in
this manual before dismounting the tractor.
•
Lock decks in the folded-up position before making
adjustments to the deck cutting height.
IMPORTANT: Linchpins should always be inserted
into the gauge wheel spindle from the front with the
locking clasp flipped shut over the spindle toward the
back. Attaching the pin in this manner will prevent
vegetation from catching on the clasp and flipping it
open while traveling forward.
IMPORTANT: Before continuing, read instructions
on raising and lowering decks starting with "U-Joint
Timing" on page 28.
Cutting height adjustments should be made with mower
hooked to the tractor that will be used for field operations
or to a tractor having the same drawbar height.
Tire pressure will affect mowing height. Make sure air
pressure in the transport tires is correct. See "Tire
Inflation Chart" on page 52.
Refer to Figure 2-1:
1.
Lower mower decks onto a flat, level surface. Refer
to "Unfold Mower Decks" on page 28.
2. Shut tractor down before dismounting. Refer to
"Tractor Shutdown Procedure" on page 16.
3. At the front of all three decks, measure
(dimension A) from top of deck to ground.
4. Use (dimensions A), with "Cutting Height Chart" on
this page to determine what cutting height
(dimension B) the mower decks are currently set.

5. If all three decks are set at the correct cutting height,
skip to "Belt Tension" on page 24. Otherwise,
continue with step 6 below.
6. Raise mower decks up to their locked transport
position. See "Fold Mower Decks" on page 28.
7.
Shut tractor down with decks locked in the folded-up
position. Refer to "Tractor Shutdown Procedure"
on page 16.
Refer to Figure 2-2 on page 23:
NOTE: The gauge wheel will need to be removed
from its support tube to add or subtract spacers
below the support tube.
8. Remove linchpin (#4), upper spacers (#6) and gauge
wheel (#12) from support tube (#7).
9. Add or remove spacers (#6) to or from gauge wheel
spindle (#5) an amount equal to the number of
inches the gauge wheel will need to be adjusted.
Adding spacers will raise cutting height and
removing spacers will lower cutting height.
10. Insert gauge wheel spindle (#5) in spindle tube (#7).
11. Add remaining spacers (#6) to spindle (#5) and
secure spindle (#5) with linchpin (#4). Make sure
linchpin is inserted from the front. Refer to
"IMPORTANT" linchpin note on this page.
12. Flip locking clasp on linchpin (#4) shut.
13. Repeat steps 8-12 for all other gauge wheels (#12)
that need adjusting.
14. When finished, all ten gauge wheels will, in most
cases, have an equal number of spacers below the
spindle tubes. See note below.
NOTE: Due to manufacturing tolerances and tire
size differences, it may be necessary to readjust
some spacers. Because of this, you may not end up
with an equal number of spacers on all gauge
wheels.
