General Rules for Moving Controls When using a foot brake, push it in; When using a hand brake, pull up. When using a foot brake, push it in; When using a hand brake, pull up. A foot clutch is disengaged when it is pushed in and engaged when let up A foot clutch is disengaged when it is pushed in and engaged when let up Hand operated engine controls (throttles) increase engine speed when moved upward or forward. Foot operated throttles increase speed when pushed forward or downward by toe pressure Hand operated engine controls (throttles) increase engine speed when moved upward or forward. Foot operated throttles increase speed when pushed forward or downward by toe pressure

General Rules for Moving Controls Direction of tractor is controlled by specific forward and reverse gears or by directional controls. If a hand operated direction control is used, the tractor moves in the same direction as the control is moved. Direction of tractor is controlled by specific forward and reverse gears or by directional controls. If a hand operated direction control is used, the tractor moves in the same direction as the control is moved. The engine stop control is by key and by mechanical push-pull control. A key is always turned counterclockwise to stop an engine. A push-pull lever is always pulled out to stop the engine. The engine stop control is by key and by mechanical push-pull control. A key is always turned counterclockwise to stop an engine. A push-pull lever is always pulled out to stop the engine. Controls that lift or lower attachments or implements are generally pushed forward, down, or away for lowering, and pulled back, up, or toward you for lifting.
