Mind you, I took shop class about 20 years ago. I have a general idea about how to do stuff (or use the stuff to get something done). Scott, however, is in an entirely different class. That man can BUILD. He took the vague ideas I had about building chicken tractors and made them work. Granted, there are still things I'd change, but he's really got the talent.
KLA (who was kind enough to comment :) ) this is for you about the wheels. I'll try to give a step by step instruction.
The wheels are mounted on a piece of 2x4 which is bolted to a 2" spacer on the side of the tractor.
(We got most of the wheels as salvage from the local dump)
See the bottom hole on the wheel strut? You pull up on the top of the 2x4, use your foot to move the wheel forward, and stick the nail in the bottom hole on the strut that matches up to the hole on the spacer. That way your wheels don't just keep going forward.

Here's a closeup of the mechanisms. Lucky you, you get to see my dirty toes.
the back of the tractor. See ma? No axle! Those blocks on top of the nest box hold the lid open without laying it over. How cool is that?
I hope this might help anyone wanting to build a tractor. Of course, I wanted to paint them but we needed them NOW. I'll bet that if you need more tips, my husband would be happy to give you some. I'll let you know about any more modifications we decide to make. Happy Chickening!
