Toro 4100-D service manual Cutting Deck Raise and Lower Switches, Adjustment Fig

Cutting Deck Raise and Lower Switches

Adjustment (Fig. 9)

1. Park machine on a level surface, lower cutting deck,

stop engine, engage parking brake and remove key

from the ignition switch. Remove console housing.

2. The cutting deck raise and lower switches can be ad-

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) should be parallel with

the center deck lift/lower lever. If lever bracket ad-

justment is needed, loosen flange bolts (item 6) and

reposition lever bracket.

C. Switch surfaces need to be parallel to each other

and also to the switch actuator on center lift/lower le-

ver (item 9). If necessary, switch plate (item 3) can be

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 the neutral

position. As the lift/lower lever is slowly pulled back,

the raise switch should open (no continuity) after the

lever has removed all free play (with no spool move-

ment in lift/lower control valve) but before the deck is

lifted.

B. The lower switch should be open (no continuity)

when the center deck lift/lower lever is in the neutral

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. If switch operation is too sensitive, increase distance

between switches by repositioning one or both

switches. If switch operation is not sensitive enough, de-

crease distance between switches by repositioning one

or both switches. Recheck operation of switches after

repositioning.

5. If switches cannot be adjusted for correct operation,

exchange position of switches. Recheck operation of

switches.

NOTE: If correct switch operation cannot be achieved, replace one or both switches. Recheck switch operation after replacement.
