RMC Module

The RMC Module is in the same housing as the key
switch and is not available separately. For the purpose of
diagnosis, it is treated separately. Diagnosis of the module
with the key switch introduces too many over-lapping vari-
ables. See Figure 7.3.
• Principle: To diagnose the module, the sim-
plest approach is to check all of the inputs
(safety circuits) that are connected to it. If the
inputs work properly, but the RMC module does
not work properly (outputs), then the module
can be determined to be faulty. A specific pro-
cedure is covered, following the description of
the correct operation of the RMC module.
• Working properly: The module cannot be
diagnosed if its function is not understood. It is
designed to work as follows: See Figure 7.4.
• When the RMC module is disarmed, the
mower will operate as MTD mowers have his-
torically operated:
• If reverse is engaged when the electric PTO
is ON, the PTO clutch will turn off.
• If the operator leaves the seat with the PTO
on, the PTO will turn off.
• If the operator leaves the seat with the PTO
in the OFF position, the engine will turn off
unless the parking brake is applied.
• When the RMC module is armed, the mower
will operate identically to when the module is
disarmed.
• When the RMC module is armed and turned
on: The mower will operate identically to when
the module is disarmed, except that the opera-
tor will be able to put the transmission in
reverse with the PTO engaged and the cutting deck will continue to run. The operator may put the mower
into and out of reverse as many times as they wish without having to re-arm or turn on the module again.
• To arm the RMC module: The operator must turn the key switch to the REVERSE CAUTION MODE (yel-
low zone), while sitting in the operator's seat.
• To turn the RMC module ON: The module must first be armed, then the orange triangular button is
depressed, illuminating the red LED indicator to indicate that it is ON. It is important that the operator must
take two actions to turn the RMC module ON so that they do not do so inadvertently.
• The RMC module will turn OFF and disarm if: The operator moves the key to any position other than
REVERSE CAUTION MODE or gets out of the seat. If the operator leaves the seat without setting the
parking brake, the engine will turn off. The key movement necessary to re-start the engine will make it
necessary to re-arm and turn on the RMC module if the operator wishes to continue with the ability to put
the mower in reverse while the PTO is running.
• To re-arm and turn the module ON: If the key is in REVERSE CAUTION MODE position, it must be
turned to another position (Normal Run), then returned to REVERSE CAUTION MODE. Once re-armed,
the module can be turned on by pressing the orange triangular button. It will be confirmed that the module
is ON by the illumination of the red LED on the module.
