Bob,
I have been seriously considering building one of those. Some may say that it's a joke but I feel like if it can save me some time, it is all worthwhile. Besides that, I have a good time constructing things. Your tractor is much bigger than mine but just because it's smaller doesn't mean that it can't have a smaller loader. I would like to be able to lift it high enough to dump into a 10 cu. ft. trailer though. I have been kicking around using electric motors and worm/screw gears for the lift. Don't know if it will be strong enough though. Seems like it kinda depends on where the lever is positioned. I think it could work and if not hydraulics could always be used. How much do you think you could lift with that? If I could load 3-4 cu. ft. of material, I would be happy. Does anyone now where I could find out material weights?
