Yeah, I know ... But my point is that you can't just use the "1000 Lb" number to figure out if it can be lifted ... A 4X5 bale is usually 4' thick, so even if the spear was at the pins, which it isn't ... The hay 4' away will have a much greater effect on the lift capabilities than the hay nearest the spear.It's a bit more complicated than that.
If it was a tall thin vertical slab of lead, yeah it should lift it a ways ...
On my Little Baby Fergie, when I was using that for water duty, I'd put a block under the front of the tote, so more water would be closer to the forks, once lifted a tad, I quick hard push on the forward pedal, while holding the lift lever back, it would slosh a bit, and I could get it raised a few feet, like you said, once it gets up high enough so it's coming back it gets easier, plus ... With water it tends to go to the low point.
I still think a MX is more what the OP should be looking for.
