Cutting Deck Raise and Lower Switches
Adjustment (Fig. 9)
1. Park machineon alevels urface, lowercutting deck,
stop engine, engage parking brake and remove key
from the ignition switch. Remove console housing.
2. Thec uttingdeckraiseandlowerswitchescanbead-
justed for correct operation by repositioning the
switch(es).
A. The distance between switches should be from
0.595” to 0.655” (15.2 to 16.6 mm) (Fig. 10).
B. The lever bracket(item 4) shouldbe parallelw ith
the center deck lift/lower lever. If lever bracket ad-
justment is needed, loosen flange bolts (item 6) and
reposition lever bracket.
C. Switch surfacesneed tobe paralleltoeach other
andalsotothe switchactuatoroncenterlift/lowerle-
ver(item9).Ifnecessary,switchplate(item3)canbe
rotated after loosening flange nut (item 5).
3. After any switch adjustment, unplug switch connec-
tor from machine harness and check for correct switch
operation using a multimeter:
A. The raise switch should be closed ( continuity)
when the center deck lift/lower lever is in theneutral
position. As the lift/lower lever is slowly pulled back,
theraiseswitchshouldopen(no continuity)afterthe
leverhas removedall freeplay (withno spoolmove-
mentinlift/lowercontrolvalve)butbeforethedeckis
lifted.
B. The lower switch should be open (no continuity)
when the center deck lift/lower lever is in theneutral
position. As the lift/lower lever is slowly pushed for-
ward, the lower switch should close (continuity) be-
fore the lever reaches full forward travel.
4. Ifswitchoperationistoosensitive,increasedistance
between switches by repositioning one or both
switches.Ifswitchoperationisnotsensitiveenough,de-
creasedistancebetween switchesbyrepositioningone
or both s witches. Recheck operation of switches after
repositioning.
5. If switches cannot beadjusted for correctoperation,
exchange position of switches. Recheck operation of
switches.
NOTE: If correct switch operation cannot be achieved,

after replacement.
