Belt for my 129 mower deck
 

Quite some time ago I got a new belt from the dealer I always bought from but recall several times over the years trying to put in on and it just always seems too short.

Some info that might help: My (IH) 42" mower deck ID is 422U1113. The number on the old belt (still usable but noticed when putting the deck back on today that it seems very stretched out) appears to be 473462-R4. Tough to read at this point but I believe that's correct.

The new belt I'm referring to that seems to not fit has the following sets of numbers: 3568 Made in Mexico; 490489-R2, and also 4 sets of numbers:
0420 246
0420 247
0420 248
0420 249

I'm assuming the longer 490 number is the belt number. Can anyone tell me if this belt is indeed the right one? And if it isn't, what part # should I be looking for?

What I'm referring to is the belt that goes from the mower center pulley up to the PTO.

Thanks for any advice...


UPDATE: just did a search on the old belt # and came across this So assuming that's what I'm looking for? Didn't know if over the years the part # might have changed. If that's the right one, I'll check around for price comparison. If that other (new) belt is the wrong one, I'll try to sell it.

Look it up on the cub cadet parts lookup site.

I came up with IH-491489-R2

Are you SURE you have a 42" deck and not a 44" stamped steel deck??
Are the ends of the deck cast iron parts?
Got a picture?

Flip it and measure blade tip to blade tip for the correct size

Digging into my Paper Catalog, the correct belt for a 129 w/42" mower deck is: IH-490489-R2 (3/8" x 80").

The IH-473462-R4 is 3/8" x 81". This belt was used on Quietline Tractors with the Electric PTO.

My reference material shows this:

Iron:

YUP, your images shows a belt for the Quietline tractors.

OP said he has a 42" deck, not a 44"

What doesn't make sense is that I would think that the deck i.d. he posted (422U1113) would be newer than model year 1963-1968 as that chart shows. (?????)

That deck was made between 1971-1974.

Here is the chart from the same Literature

Thanks Roland. That matches this "new" belt that I have here but, as I said, I've never been able to get it to go on - it just won't reach both the two pulleys in the front where the belt turns the corner and goes up to the PTO. I'd say it is about an inch too short! So...not sure what to do. Go with the 81" belt?
