Important: Do not push or tow the
machine faster than 2 to 3 mph because the
transmission may be damaged. If the machine
must be moved a considerable distance,
transport it on a truck or trailer. Whenever the
machine is pushed or towed, the by-pass valve
must be open.
1. Loosen the knob and remove the access
cover at the rear of the seat mounting plate
(Figure 29).

2. Press and hold the pins located in the center
of the 2 check valve assemblies in the top of
the transmission (Figure 30) while pushing or
towing the machine. Figure 30 is shown with
seat and seat mounting plate removed.

3. Start the engine momentarily after the repairs
are completed and make sure the pins are in
the full disengaged (fully up) position.
Important: Running the machine with
the by-pass valve open will cause the
transmission to overheat.
4. Install the access cover.
Standard Control Module
(SCM)
The Standard Control Module is a potted
electronic device produced in a one size fits all
configuration. The module uses solid state and
mechanical components to monitor and control
standard electrical features required for safe
product operation.
The module monitors inputs including neutral,
parking brake, PTO, start, backlap, and high
temperature. The module energizes outputs
including PTO, Starter, and ETR (energize to run)
solenoid.
The module is divided into inputs and outputs.
Inputs and outputs are identified by yellow LED
indicators mounted on the printed circuit board.
The start circuit input is energized by 12 VDC.
All other inputs are energized when the circuit is
closed to ground. Each input has a LED that is
illuminated when the specific circuit is energized.
Use the input LED's for switch and input circuit
troubleshooting.
Output circuits are energized by an appropriate
set of input conditions. The three outputs include
PTO, ETR, and START. Output LED's monitor
relay condition indicating the presence of voltage
at one of three specific output terminals.
Output circuits do not determine output device
integrity so electrical troubleshooting includes
output LED inspection and conventional device
and wire harness integrity testing. Measure
disconnected component impedance, impedance
through wire harness (disconnect at SCM), or by
temporarily test energizing the specific component.
The SCM does not connect to an external
computer or hand held device, can not be
re-programmed, and does not record intermittent
fault troubleshooting data.
The decal on the SCM only includes symbols.
Three LED output symbols are shown in the
output box. All other LED's are inputs. The chart
below identifies the symbols.
