John Deere hay bale fork or spear 600 & 700 series or trade

I have a hay fork or spear that fits a john deer 600 or 700 series loader. It's a single spear with two further stabilizing short spears and a flat bar to further stabilize the round or square bale. No longer have the tractor so I'm selling it. Fairly good condition, had it for a while. I'm asking $500 I would like to trade towards an ALO spear. Let me know if you have anything

I'm located about 10 Km outside of Lindsay. Thank you
