Murray 20 HP 46" cut belt

[Gerry Neese]

I have a Murray 20 hp 46 in cut V-Twin/ohv autodrive but do not know the year......I need a cutting belt (not drive) for the right side blades. Does anyone lknow what size belt i will need? Found broken belt with a number on it.....37x66 710216 is this the belt

They made many different 46 inch cut mowers, you need to find the model numbers off of the tag on the rear of the tractor.

Gerry,
Don't know if you have found your belt yet or not but my parts book shows 37x66 to be the "Belt, Secondary Mower Drive". This is the shorter of the two blade drive belts and runs from the stacked pulley at the middle blade to the LEFT side blade as you sit on the mower. The right blade receives power from the 37x69 "Belt, Primary Mower Drive" This is on my 1993 (?) 46 inch 20 hp Murray model number 46209x9c. Like Fish said if you can find the model number on the rear of the mower it can help a lot. Hope this helps.
