Matching the Height of Cut
Between Mower Decks
1. Position the blade side to side on the outside
spindle of both wing mower decks.
2. Measure from the floor to the tip of the cutting
edge on both units and compare.
Note:
These numbers should be within 3 mm
(1/8 inch) of each other.
3. Add or remove shims (1/8 inch) as needed on
side castor wheels.
4. Check the measurement between the outside
edges of both wing mower decks and adjust as
necessary.
5. Position the blade side to side on the inside
spindle of side cutting unit and corresponding
outside spindle of the front cutting unit.
6. Measure from the floor to the tip of the cutting
edge on inside edge of side cutting unit to
corresponding outside edge of front cutting unit
and compare.
Note:
These numbers should be within 3 mm
(1/8 inch) of the front cutting unit.

Note:
All three cutting units castor
wheels should remain on the ground with
counterbalance applied.
Note:
If adjustments need to be made to match
the cut between the front and side cutting units,
make the adjustments to the side cutting units
only.
7. If the inside edge of the side cutting unit is too
high relative to the outside edge of the front
cutting unit, remove one 3 mm (1/8 inch) shim
from the bottom of the front inside castor arm on
the side cutting unit
8. Check the measurement between the outside
edges of both the side cutting units and the
inside edge of side cutting unit to the outside
edge of front cutting unit.
9. If inside edge is still too high, remove an
additional 3 mm (1/8 inch) shim from bottom of
front inside castor arm of the side cutting unit
and one 3 mm (1/8 inch) shim from the front
outside castor arm of the side cutting unit.
10. If the inside edge of the side cutting unit is too
low relative to the outside edge of the front
cutting unit, add one 3 mm (1/8 inch) shim to
the bottom of the front inside castor arm on the
side cutting unit.
11. Check measurement between outside edges of
both side cutting units and inside edge of side
cutting unit to outside edge of front cutting unit.
12. If inside edge is still too low, add an additional 3
mm (1/8 inch) shim to the bottom of front inside
castor arm of the side cutting unit and add one
3 mm (1/8 inch) shim to the front outside castor
arm of the side cutting unit.
13. Once cutting height matches at the edges of
front and side cutting units, verify that side
cutting unit pitch is still 8 to 11 mm (5/16 to 7/16
inch). Adjust as necessary.
