I have a set of forks for the loader on the tractor as well. I think I use the tractor as a forklift more than any other task. I am on the lookout for a 2 stage mast to make a 3 point attachment for the tractor some time or maybe one for the loader. I have some thoughts on that, makes me dangerous LOL
I opted to put the forks on the 3pt because the FEL has somewhat less lift capacity, especially as the load moves farther forward from the front pivot pins. Obviously I haver very limited lift height with my 3pt set up.
I also decided to make mine modular so it could be used for multiple different tasks.
I started with a simple "Howse" brand potato plow and decided to use that as the basis for an under-ground cable layer. That got me thinking about making a fork lift and a trailer mover.
The red part in the photo was purchased, that is the frame from the Howse unit. I designed the black rectangular frame that holds the pallet forks to sit on top of the potato plow frame when the potato plow frame is mounted BACKWARDS on the tractor. Its held in place by a single heavy duty hitch pin. The forks are surplus from an old forklift.
