What about making it similar to these jacks with a castor on the bottom.
It has a clamp that holds the jack tube, you flip the lever you can see if you look closely, and it is like a quick release. You can then drop the jack tube down to the desired height and tighten the clamp. You could put a castor on the bottom of it and when you want it, lower it, when you don't lift it out of the way. Only question would be if it lifts if high enough to actually get it out of the way.
Just an idea.
Btw, Nice tractor.
I just love ideas people come up with. BTW that is a fine looking trailer. What is the finished result going to be. I'm thinging a camper, or a portable hunting blind.:smile1:
That ideal is neat, however the front of the tractor when using a tiller dips quit low when turning at the end of the row. I'm working on a way to remove just the swivel wheel for those times it needs to come off in a hurry. I'll post the results.
I sure appreciate the ideals you and others provide on this site. This is still my go to site on the web.
