I use my chains mainly for dragging trees out of the bush so drilled holes for small hangers on my Kubota L275DT. I like being able to rehang the chain at the back of the tractor as soon as I've dragged the tree.
I also installed some small brackets on existing bolts on each side of the loader arms and use them for carrying long items such as a rake, shovel, log lifter, axe, etc., thus freeing the bucket to bring back wood.
I just purchased a Kioti DK35 which does not have similar bolts. But the dealer is also a machine shop and they are going to rig up hooks at the rear (likely a cross piece between the ROPS mounts) and weld brackets to the underside of the loader arms.
