Reverse Mower Control (RMC) circuit operation
Historically, Cub Cadet home owner mowers have not been able to mow in reverse. This has not been required
by any laws or safety regulations, it was just safer for our customers and those around them. In 2005 we introduced
the Reverse Mower Control that allows the operator to over-ride the circuit that turns the mower deck off in reverse.
We want to make sure that the operator of a mower with
Reverse Mower Control is always cognizant of the risks that
they take upon themselves by mowing in reverse. To
accomplish this, we make the operator take two distinct
actions: See Figure 7.32.
1. The operator must arm the RMC module by turning the
key switch to the Reverse Caution Mode position.
2.
Once armed, the RMC module must be engaged by
pressing the orange triangular button on the front of
the module. When it is armed and engaged, a red
LED on the face of the module lights-up.
If the operator gets out of the seat, the mower has no way of knowing if the same person had gotten back into
the seat. For that reason, the module shuts-down and dis-arms itself whenever the seat is vacated. The person who
gets back in the seat must then re-arm the module by turning the key out of and back into the Reverse Caution Mode
position.
The easiest way to understand the RMC circuit is to
think of the RMC module as a switch that obeys com-
mands.
In normal operation, the reverse safety switch and one
set of contacts in the seat switch simply pass through the
module to connect with the yellow/black trace wire that
triggers the PTO relay by providing a ground for the wind-
ings. See Figure 7.33.
