Features: These three series of wing-fold offset disks are ideal for growers who must transport their equipment on the highway from one field to another. The patented hydraulic folding mechanism allows for using small 3 1/2" x 10 cylinders, folding to a transport width of only 15'3". All four wing cylinders are operated from one remote hydraulic valve on the tractor. Each wing is equipped with a flow control valve which limits the speed of raise and lower at a safe and smooth level of operation. The drawbar design permits shorter turns behind dual wheel tractors. Leveling linkage keeps disk level in all stages from disking to transport. Two heavy compression springs absorb shock loads.
