IMPORTANT NOTE: The GX Series Grapples ship with two female 1/2 in. hydraulic quick couplers on the grapple’s hydraulic hoses to plug into the tractor’s 3rd function valve couplers, plus one loose 1/2 in. male coupler. If the tractor’s 3rd function has different coupler types or sizes, any farm & ranch supply store will have the necessary couplers to adapt the connection points.
