- NOTE -
To prevent the cutter deck from teetering, all four
(4) cutter deck hanging chains must have tension
on them. If all four chains do not have tension on
them and the deck teeters, you must readjust the
cutter deck as outlined in the procedures above.
CUTTER DECK HEIGHT
The cutter deck height adjustment is made to ensure that
the cutter deck is cutting at the height indicated on the
cutting height index gauge. To check for proper deck height,
be sure that the mower is on a flat, level surface and the
tires are properly inflated.
Place the cutter deck in the transport position. 1.
Loosen the jam nuts on both ends of the deck height
control rod. (See Figure 6.7)

Check the cutter deck cutting height by placing the 3.
lanyard pin in the 3" position on the cutting height
index. Release the deck from the transport position
and allow the deck to move to the 3" cutting height
position.
Check the measurement from the floor to the 4.
cutter blade tip. If the measurement is not at 3",
an adjustment can be made using the deck height
control rod. (See Figure 6.7)
- NOTE -
If an adjustment had to be made, be sure that the
cutter deck can easily be locked into the transport
position.
