54" deck belt P/N confusion

[GearHead36]

I have a Pro Z 154 with a deck belt that needs to be replaced. The parts list shows the P/N as 954-05013. When I search that P/N on cubcadet.com, I get two hits. One for that P/N, which shows as in stock, and one for 490-501-C094, which shows as the replacement for 954-05013, also in stock.

The description for 954-05013 is "V-Belt B Sec x 154"

The description for 490-501-C094 is "54-inch Z-Force Deck Belt"

What's the difference? Which one do I need? And why is the replaced part still available?

The engine is 27HP, and under heavy load, the belt slips... a lot. I suspect that's mostly due to an oil leak that probably got oil on the belt, but the belt also has a lot of nicks, so I want to replace it with the best belt that will slip the least. And yes, I plan on cleaning the pulleys first.

These belts are around $80, so I'd like to get the right one the first time.

Packaging. 954-05013 is the MTD retail packaging and the 490-501-C094 is the Cub Cadet packaging. Same belt For both costs the same.

That's a bit surprising... the MTD P/N was on the parts list for my Cub Cadet.

Thanks.

Not considering some the new S mount blades can have three or four different pn depending how they are package.
