Adjustments
Adjust Accelerator Cable
NOTE: Workman GTX vehicles use the engine gov-
ernor to control engine speed. Refer to the Kohler Ser-
vice Manual for additional governor information.
Depressing the accelerator pedal rotates the engine
mounted throttle lever which tensions the engine gover-
nor spring to increase engine speed. Releasing the ac-
celerator pedal decreases governor spring tension
which reduces engine speed.
NOTE: Two (2) people are needed to complete this pro-
cedure. Also, a tachometer is necessary to measure en-
gine speed.
1. Park machine on a level surface, stop engine, en-
gage parking brake.
2. Raise cargo bed and prop with rod to gain access to
the engine.
3. Make sure that shift lever on steering column is in the
neutral position to prevent the vehicle from moving.
NOTE: If phototac is to be used to measure engine
speed, DO NOT use secondary clutch on transaxle for
speed measurement.
4. Start engine and fully depress accelerator pedal.
Have a second person measure engine speed with a ta-
chometer. With pedal fully depressed, engine speed
should be from 3650 to 3750 RPM. If necessary, adjust
jam nuts on accelerator cable so that engine speed is
correct when the accelerator pedal is fully depressed.
5. After accelerator cable adjustment is correct, lower
and secure cargo bed.
