I would go to Tractor supply look for wheels needed. Agrisupply has 64 wheels listed.

Here is a link that might be useful: wheels

I have a Cultivator Plus that I bought new in 1985. I've been very happy with it but I also need new wheels for it. I have one wheel that I taped with electrical tape last year.
today when I was using it the other tire came off the rim so I will have to tape it unless I can find some wheels. I bought a new carburetor for it this year and it runs much better.

I just bought one of these @ yard sale 80.00 put a new carb , runs great. thanks everyone.

does anyone know what tine seal to use the one in parts book no longer available ? cross over #?
