Matching the Height of Cut
Between Mower Decks
1. Position the blade side to side on the outside
spindle of both side mower decks.
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 mower deck and
corresponding outside spindle of the front
mower deck.
Note:
Measure from the floor to the tip of
the cutting edge on the inside edge of side
mower deck to the corresponding outside edge
of front mower deck and compare. The side
mower-deck measurement should be within 3
mm (1/8 inch) of the front mower deck.
