Hey Old Buzzard, yes, just like that. Or if the ground was rough, or to help slow down to cut around obstacles. As has been mentioned, there are two belts, plus one central pulley. The engine end is fixed, so is the transmission end. The pulley is a special double pulley where the central divider is free to move back and forth. The pulley moves towards and away from the engine. As it does that, the engine belt is moves closer and further from the center of the pulley. The transmission belt always moves in the opposite direction from the engine belt, thus creating a variable ratio from front to rear.OK, I guess that if you were mowing, you can leave it in the same gear, but slow it down a bit if you run into some heavier grass in order to keep the blade speed up?
