So we got the forklift.
Lifted the box. Took the pins out of the hydraulic cylinder.
And then the cylinder retracted. So the problem was not a bad cylinder, but rather that the box is in a bind when yet is up in the air. Nothing looked wrong. Of coarse this all happened when The sun was shining in the rear window, and it was too bright to see the box.
By the time we got the box back together it was dark.
I filled it up again and dumped it. I was very careful. Then a fountain of silage sprayed out of the fan on the chopper. There was a hole in the blower band.
I decided to quit.
perhaps we will get our first load in before lunch.
