I will probably turn the wheels into some garden art.
I found it on my property while walking the dogs, it's surprising to find something laying at the edge of a field that I have walked by at least a hundred times.
Is a planet junior a walking type planter?
Looks to be a 300A Planet jr. Those things are tough, and looks like the bottom ofthe hopper with the drive shaft and seed cut off are lying up onthe rock behind it. You could clean it and either put it back to handles or make up the simple brackets it would take to use it behind a tractor.
