Maintenance
• Side Discharge Units: The back tips of the
side blades should measure 3 1/4 inches (8.3
cm).
• Rear Discharge Units: The back tips of the
side blades should measure 3 inches (7.6 cm).
12. Re-measure until all four sides are the correct
height. Tighten all the nuts on the deck lift arm
assemblies.
13. Lower discharge deflector (side discharge units
only).
14. If the four deck adjusters do not have enough
adjustment to achieve accurate cut height with the
desired rake, the single point adjustment can be
utilized to gain more adjustment (see Figure 43).

3. Rear height-of-cut plate mounting bolt
15. To adjust the single point system, first loosen the
front and rear height-of-cut plate mounting bolts.
Note: On Rear Discharge Units: The mower
deck is attached in the front holes at the factory
(see Figure 44). If needed, use the back holes for
further adjustment when leveling the mower deck.

16. If the deck is too low, tighten the single point
adjustment bolt by rotating it clockwise. If
the deck is too high, loosen the single point
adjustment bolt by rotating it counterclockwise.
Note: Loosen or tighten the single point
adjustment bolt enough to move the height-of-cut
plate mounting bolts at least 1/3 the length of
the available travel in their slots. This will regain
some up and down adjustment on each of the
four deck links.
17. Re-tighten front and rear height-of-cut plate

mounting bolts.
Important: Torque the front and rear
height-of-cut plate mounting bolts to 27-33
ft-lb (37-45 N-m).
