The loader took them off.
Two of us loaded them by hand, no ramps!!
Well, the other guy's dad helped to push, a little!
We did not use the ramps, too many flat tires. They will not go up a ramp with flat tires.
I did tilt the trailer dump a little 'til we got them on, then just slid them on the steel bed. The steel was wet from a little drizzle, it was relatively easy.
