The speed control potentiometer controls the electric
motor speed which determines traction and cutting reel
speed. The T EC controller uses the potentiometer set-
ting as an input to determine the necessary signal output
for the motor controller for correct electric motor speed.
The speed control p otentiometer is a ttached to the
speed control assembly on t he handle ( Fig. 49).
Speed Control Potentiometer Operation
Speed control potentiometer operation can be checked
with theInfoCenter. With the key switch in the RUN posi-
tion and theInfoCenter in theDiagnostics menu, choose
Throttle and make sure that the displayed voltage
changes as t he speed wheel is rotated. Further poten-
tiometer testing is necessary only if the displayed volt-
age does not change when using the InfoCenter.
