General Rules for Moving Controls n n 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. 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. A PTO is usually engaged when pulled up or pushed forward.
