Cutting Unit Position Switch
The cutting unit position switch is a normally open prox-
imity switch that is located on the front carrier frame
(Fig. 27). When a gusset on the front right cutting unit
(#5) lift arm passes in front of the switch, the switch clos-
es. The cutting unit position switch provides an input for
the Toro Electronic Controller (TEC) during various ma-
chine operation modes.
Adjustment
The gap between the cutting unit position switch and the
lift arm gusset should be 0.063” (1.6 mm). If distance is
incorrect, loosen jam nuts that secure position switch to
bracket. Adjust switch location with jam nuts to allow
correct gap between switch and lift arm gusset. Jam
nuts should be torqued from 13 to 17 ft−lb (17.6 to 23.0
N−m). After jam nuts are tightened, make sure that gap
has not changed.
The vertical location of the cutting unit position switch on
the switch bracket will determine the height of the cutting
unit turn−around position. Raising the switch on the
bracket will allow a higher cutting unit turn−around posi-
tion. Lowering the switch on the bracket will allow a low-
er cutting unit turn−around position. Loosen the cap
screws (item 3) and adjust the switch bracket as neces-
sary.
4. Check for proper cutting unit position switch opera-
tion after adjustment (see cutting unit position switch
testing in this chapter).
