Neutral and Mow Switches
The neutral and mowswitches are normally openprox-
imity switchesthatmount tothe console assembly(Fig.
17).The sensingplate fortheseswitchesis atab onthe
functional control lever. The Toro Electronic Controller
(TEC) monitors the operation of the neutral and mow
switches.
When the functional control lever is in the neutral posi-
tion,thetabontheleverispositionednearthetargetend

on the functional control lever is moved away from the
neutral switch when the lever is in either the mow or
transport position causing the switch to be in its normal
open state.
Whenthe functionalcontrolleveris inthemowposition,
the tab on the lever is positioned near the target end of
the mow switch causing the switch to close. The tab on

Adjustment
1. Remove console cover from console assembly to
gain access to switches (see Control Console Disas-
sembly in the Service andRepairs section of Chapter 7
-- Chassis).
2. When the functional control lever is placed in the
neutral or mow position, the gap between the appropri-
ate switch head and the tab on the functional lever
shouldbefrom0.090”to0.120”(2.3to3.0mm)(Fig.20).
3. Ifgapisincorrect,loosenjamnutsthatsecureswitch
toconsolebracket.Positionswitchwithjamnutstoallow
correct gap between switch head and functional lever
tab. Tighten jam nuts to secure adjustment. Jam nuts
should be torqued from 162 to 198 in--lb (18.4 to 22.3
N--m). After jam nuts are tightened, make sure that
clearance between head of switch and tab on the func-
tional lever has not changed.
4. After adjustment tothe switch(es),use the Diagnos-
tic Display to verify that neutral and mow switches and
circuit wiring are functioning correctly (see Diagnostic
Display in the Troubleshooting section of this chapter).
5. Secure console c over to console assembly (see
Control Console Assembly in the Service and Repairs
section of Chapter 7 -- Chassis).
