I would like to order this part online, but don’t know what to look up.
Toro 42 inch riding mower Model: 12AT609G766 Serial: 1K294H10129.
The deck belt that drives the blades goes through several pulleys. The pulley on the drivers side (left) come apart. I have a thing donut looking thing with what looks like the center still attached by a big nut to the blade shaft. I need to replace this pulley. What is it called and where is a good place to find one on the internet.
I ordered some parts for my dad from this site:
We ended up ordering the wrong thing, because we didn’t know the exact right part. I emailed them, and they were very helpful. They sent me a link to a parts diagram and we were able to get exactly what we needed.
It looks like they don’t have your exact model, but there’s a link to a parts request form:
Another thing you can try, is to locate your manual online. If you can find a diagram, and the exact part number, you can google that.
If that model number is correct, it is likely it is an old model. You get no hits when you google that number, which would be odd even if it was an old model (Even the Toro site does not recognize that number). If you have not tried this already, go Here to see if you can get the right model number. If the number is correct, I suggest you look at the current 42" riding mower’s manual, look for that part and try to ascertain if the specs are the same. Once you have the part number, just google it. I did this for my own mower just yesterday & found the part being sold on ebay.
Good luck.
