Yard Pro was a brand name sold by AYP/Electrolux/Husqvarna. Still being sold and serviced as Sears/Craftsman and Husqvarna.

However, I can't make your Model number work, either. Suggest you look at Sears parts website or get one of the PDF manuals from Electrolux/Husqvarna. Transmissions for the CRT fillers are pretty much the same, and parts are available.

well, got the tiller back out today. Still have not found any info on it. Model number is YPRT150HR serial number is 2639SO2731. I can't seem to find a manual anywhere....

does your tiller look like the one you find when you type in PRRT900? If it is, I have one of that design that is about 10 0r 12 years old, but only has a 6.5 engine on it. AYP made many tillers of that design.

I have locked up my tines by getting rocks hung in them and it would kill the engine.

It does look like that. I have had it for at least 17 years. My father in law gave it to me. I have no idea how long he had it before that. They are so expensive now I really want to try and fix it. There is nothing in the tines that I can see.

Does it look like this one?
