I have an old JC Penney mower that I bought used. I'd like to find out
whatever I can about it, so I can get parts and fix it.

It is s self-propelled mower with a large rear wheel; the tire tread is
actually gear teeth that are driven by a small gear off the motor. It is
22", 5hp, and the model number starts 0344A.

Thanks for any info.
