Tri-L’s JD 400/500 Single Front Loader bale spear is ideal for handling round hay bales. The single penetrating spear easily slides in and out of the bale, allowing for secure, quick loading and unloading. The two stabilizers keep the bale in place. Our 500 series frame has both the John Deere compact and utility tractor pin mounts that will fit the 300, 400, and 500 series John Deere loaders.
