cutting edge.
3. Adjust the shims (3 mm or 1/8 inch) on the front
caster fork(s) to match the height-of-cut decal
(Figure 35); refer to

Between Cutting Units
1. Position the blade side to side on the outside
spindle of both side cutting units.
Note:
Measure from the floor to the tip of the
cutting edge on both units and compare. These
numbers should be within 3 mm (1/8 inch) of
each other. Make no adjustment at this time.
2. Position the blade side to side on the inside
spindle of the side cutting unit and corresponding
outside spindle of the front cutting unit.
Note:
Measure from the floor to the tip of the
cutting edge on the inside edge of side cutting
unit to the corresponding outside edge of front
cutting unit and compare. The side mower-deck
measurement should be within 3 mm (1/8 inch)
of the front cutting unit.
Note:
All 3 cutting unit caster wheels should
remain on the ground with counterbalance
applied.
