You can adjust the throttle on a Massey Ferguson tractor by adjusting the governor arm at the throttle linkage. The governor arm is the part located on the side of the throttle linkage that is connected to the governor, and when it is adjusted, it will adjust the throttle setting.
To adjust the throttle on a Massey Ferguson tractor, start by disconnecting the governor arm from the governor. Then move the throttle arm to the desired setting.
Once the desired setting is reached, reconnect the governor arm to the governor then secure it with the retaining clip. You may need to slightly readjust the arm to make sure it is secure.
Once the arm is secure, start the engine and check the throttle setting. If the throttle is too low or too high, readjust the governor arm until the desired engine speed is achieved.
