I don't recall the part number for the belts. I took one belt into the local auto parts store, They read the numbers off the belt. I asked for a matched set of premium grade belts.

The parts store had the belts on hand.
I have an excuse. CRS.

The words "Matched Set" is very important. Considering how difficult these are to replace, you may want to spend the big bucks of getting these from the dealer. The dealer supplied belts are very stiff compared to similar sized belts from an auto parts store.
Hamiltonbobscubs recommends installing a second set of belts in at the same time. Here's a link to their tips.

The belt is a Gates 11M710 Polyflex belt. This is a non-standard V belt with a metric width and a 60 degree groove for the pulley. A standard "A" series or "L" series will not fit the pulley, they use a 35 degree or so belt angle. NAPA stores would likely not have in stock but should be able to get the belt. Lots of online dealers also. I have ordered from vbeltsupply before with good service.

I would not worry about a matched set if the belt is a name brand. Gates would make the belts within tolerance without needing to worry about matching punch codes.

A Polyflex belt should last 20 years or so, I would not buy an extra 2 belts as HamiltonBob suggests, seems like a waste of money.

A standard V belt will go around the pulleys but will ride about 3/16 inch above the top of the pulley due to the shallower groove angle in the pulley. I had an unused set of Gates AX26 belts so I installed them on my 154 and it now has around 10 hours of mowing. So far so good but I don't expect them to last all that long, certainly not 20 years. I had the belts so I thought I would see how long they last. If you want to try a standard V belt then an "A26" or 4L280 would be close.
