I purchased a walkie style forklift for $100 that needed batteries. I removed the mast and welded a 3 point attachment to the mast. I hooked up the hydraulics to the remote hydraulics on the tractor.
This is extremely useful! As pictured here, I am moving water to cows. My 3 point is rated for 2,000 pounds and I have a heavy dozer blade on the front for counterweight.
I use this for loading and unloading pallets of materials like bricks, concrete, steel. I use it to move round bales of hay. It pretty much gets used for all the heavy lifting around the farm.
