in 2 stages. To change the speed, depress the clutch

Left and right pedals can be operated separately. For a 
sharp turn in the field, depress the brake in which 
direction you want to turn. The rear tire on that side will 
lose drive, providing a sharp turn. For traveling on road, 
never fail to link both pedals with the connector.
