This series of wheel rakes are the professional haymakers' choice. They offer high-volume haymakers the dependable, adjustable high-speed raking they are used to gather up big quantity of hay quickly in all types of crop and field conditions. Each rake wheel, suspended by an adjustable spring, uses an innovative compression spring and linkage pressure system. The rake wheel pressure can be finely adjusted to the crop and field conditions for the cleanest possible raking and added reliability as there are no chains or springs under tension that can work loose or fail. Specially curved rake-wheel arms provide more space for the hay to travel along the rake wheels without bunching to form a smooth, uniform windrow.
