The engine speed is controlled with the throttle lever that is connected to an electronic sensor inside the console.
The throttle lever in the cab should move the throttle sensor the full range between slow speed stop and full rpm

If the throttle lever is contacting the console and interferes with specified engine speeds, the sensor position may
need adjustment. See your MacDon Dealer.
