The Operator’s Manual provides information regarding
the operation, general maintenance and maintenance
intervals for your Groundsmaster machine. Refer to the
Operator’s Manual for additional information when ser-
vicing the machine.
Toro Electronic Controllers (TEC)
Groundsmaster 5900 and 5910 machines use two (2)
Toro Electronic Controllers (TEC) to manage machine
electrical functions. The controllers are microprocessor
controlled that sense the condition of various switches
(inputs) and direct electrical power to control appropri-
ate machine functions (outputs) based on the inputs.
Communication between the two Toro controllers, the
Cummins engine controller and the Info Center Display
is provided with a CAN bus system. The status of inputs
to the controllers as well as outputs from the controllers
can be monitored with the Info Center Display.
IMPORTANT: Before performing any welding on the
machine, disconnect the battery cables from the
batteries, disconnect the wire harness connectors
from both Toro Electronic Controllers, disconnect
the wire harness connectors from the engine con-
troller and disconnect the terminal connector from
the alternator to prevent damage to the machine
electrical system.
The controllers appear identical but they are different in
termsoftheconnectorsandinternalhardware.Theyare
arranged in ”master / slave” configuration and therefore
cannotbeinterchanged.TheTEC--5002mastercontrol-
ler is responsible for powering up both the TEC--5001
slavecontroller andtheCummins engine controller.The
TEC--5002 also controls the engine start circuit.
Cummins Engine Electronic Control Module (ECM)
The Cummins engine thatis usedin theGroundsmaster
5900
and 5910 uses an electronic control module
(ECM) for engine management and also to communi-
cate with the TEC controllers and the Info Center Dis-
play on the machine. All engine ECM electrical
connectors should be plugged into the controller before
the machine ignition switch ismoved fromtheOFFposi-
tion to either the RUN or START position. If the engine
ECM is to be disconnected for any reason, make sure
thatthe ignitionswitch isin theOFF positionwith thekey
removed before disconnecting the engine ECM.
