The way I did mine after loading them was........I used my floor jack to raise it, rolled 1 tire over and adjusted the jack to get one bolt started, then worked jack to get a second(I ain't trying to hold a loaded tire in the air, LOL), then tightened it down. Then I did the same with the other side. These tractors are small enough that you can swivel the jack while it's in the air, so you can see the holes, and work the handle at the same time.
That is the way I did it on the 8N.
