Mow/Transport Switch
The mow/transport switch is a normally closed proximity
switch that opens when the mow stop lever is placed in
the transport position. The sensing plate for the mow/
transport switch is the mow stop lever. The switch on
machines with a serial number below 310000000 is dif-
ferent than the switch on machines with serial numbers
above 310000000 but the switch function is the same.
Testing
1. Before disconnecting the mow/transport switch for
testing, the switch and its circuit wiring should be tested
as an ECM input with the Diagnostic Display (see Diag-
nostic Display in the Troubleshooting section of this
chapter). If the Diagnostic Display verifies that the mow/
transport switch and circuit wiring are functioning cor-
rectly, no further switch testing is necessary. If the
Diagnostic Display determines that the mow/transport
switch and circuit wiring are not functioning correctly,
proceed with testing procedure.
2. On machines with serial numbers below 310000000
(Fig. 41), test mow/transport switch as follows:
A. Make sure ignition switch is in the OFF position.
Disconnect the wire harness electrical connector
from the switch. Check the continuity of the s witch by
connecting a multimeter (ohms setting) across the
switch connector terminals.
B. There should be continuity (closed) between the
switch terminals when the mow stop lever is in the
mow position. There should not be continuity
(open) between the switch terminals when the mow
stop lever is in the transport position.
3. On machines with serial numbers above 310000000
(Fig. 42), test mow/transport switch as follows:
A. Turn ignition switch to the ON position (do not
start engine) and check LED on cable end of mow/
transport switch.
B. LED should be illuminated when the mow stop
lever is in the mow position. LED should not be illu-
minated when the mow stop lever is in the transport
position.
C. The distance between the mow/transport switch
and the mow/transport lever should be from 0.040” to
0.100” (1.1 to 2.5 mm). If distance is incorrect, loosen
jam nuts that secure switch to machine frame. Posi-
tion switch with jam nuts to allow c orrect clearance
between switch and lever. Jam nuts should be
torqued from 162 to 198 in--lb (18.4 to 22.4 N--m).
After jam nuts are tightened, make sure that clear-
ance has not changed.
NOTE: When installing the mow/transport switch on
machines with serial numbers below 310000000, place
switch plate tab into switch mounting hole that is closest
to target end of switch.
4. If mow/transport switch is faulty, replace switch.
5. If the mow/transport switch tests correctly and a cir-
cuit problem still exists, check wire harness (see Wiring
Schematic and Circuit Drawings in Chapter 9 -- Electri-
cal Diagrams).
6. Make sure that wire harness electrical connector is
connected to the mow/transport switch after testing.
