oh you are correct I see the issue.Yeah, I looked at that. Several reviews say the pins are located too high for a small tractor, and they can't get their loads much off the ground.
I've got it on my "think about it" list, though. I did find a fork attachment online that weighs 50 pounds less, and is a proper fork, and has the pins located much lower. Same price, but $99 shipping. Might be worth it, though, if it works out of the box.
My carry all is 15 1/2 from ground to center of lower pins.
The issue would be moving top link.
