TCM (Tractor Control Module) Explanation
A
The Tractor Control Module (A) is a sealed computer-
ized device designed to control the electronic safety
related functions of this tractor. Both solid state and
mechanical components are used to assure safe,
reliable operation of this machine.
This TCM monitors the electronic circuits necessary
for the engine, starter, and PTO to function. These
“input” circuits include the PTO Switch, Neutral Switch,
Parking Brake Switch, Key Switch, Seat Switch, and
Generator Presence. The TCM is programmed to
allow the engine, starter, or PTO to operate only when
specific input criteria are satisfied. The engine, start,
and PTO are controlled by “outputs” from the TCM.
For additional information, refer to the TCM section
of the troubleshooting guide.
