Which one?
 

Ok, the belt chart shows 2 belts for my 125. Measuring it is out since it is in three pieces. Any way else to tell which one is correct? Also, somewhere I saw a post saying there are two different mule drives, one for mowing and one for snow blowers. Does any one have the link to this discussion? Thanks in advance.

Exactly what belt do you need? ( mower drive belt? )

I use the same mule drive for mowing and roto tilling on my 125s. My QA 42 snow thrower quick attach mount uses a short belt to drive the gear box.

What is your deck size? If you have 38 or 42 you need an 81" belt

Its a 48 and I need the one from the pto to the deck.

Not sure where you get your information, but I only see one belt for the 48" deck in the belt chart.

If not mistaken it shows a 3/8x75 1/2 and a 1/2x80.

It shows a 3/8x75 1/2 and a 1/2x80. Not sure which is which.

Awhile ago somewhere there was a thread about one mule drive had angled pulleys and one had straight pulleys. Someone said one was for the mower and one was for the blower. Just wondering if this is the reason it eats a belt evry year.

The 1/2" X 80" belt is the deck belt, for the spindles...

Blower doesn't need a mule drive, the pulley for it is in line with the PTO, no fun angles to bend around. You want the 3/8x 75 1/2 belt. Best of luck!
