1. Mow speed limiter
2. Mow/transport switch
The mow/transport switch is a normally closed proximity switch that opens when
the mow speed limiter is placed in the T
to a bracket on the footrest platform
mow/transport switch is the mow speed limiter.
The Toro Electronic Controller (TEC) monitors the operation of the mow/transport
switch.
1. Park the machine on a level surface, lower the cutting decks, set the parking
brake, and shut off the engine.
2. Before you disconnect the mow/transport switch for testing, ensure that
you test the switch and its circuit wiring as a TEC electrical input with the
InfoCenter display; refer to
(page 5–26).
3. If the input testing verifies that the mow/transport switch and circuit wiring are
functioning correctly, no further mow/transport switch testing is necessary.
4. If the input testing determines that the mow/transport switch and circuit wiring
are not functioning correctly, proceed with the test.
5. Locate the mow/transport switch
6. Turn the key switch to the R

Adjusting the Mow/Transport Switch (page
switch and return to step 6.
B. Ensure that the key switch is in the O
mow/transport switch connector from the platform wire harness.
C. Use a multimeter (ohms setting), check that the platform wire harness
connector terminal for black wire is closed (continuity) to the ground.
