Cub Cadet LTX 1050 Deck Belt

They may be 20 times stronger (I doubt it) but if they are, they don't need to be. The last NAPA belt I had on had almost 400 hours on it when it was ruined by a frozen idler pulley. I'll let you know when this NAPA belt fails.

FWIW, if there is any 'automotive' application for this NAPA belt, I'm not aware of it.

If you gat a power rated belt from NAPA then it should be close to OEM quality.
However when most fit a belt from NAPA they seem to go for the cheapest belt which is the cotton / polyester reinforced fan belt construction and not up the workout they get on a mower.
Gates make a whole range of Lawn & Garden products belts as do Oregon and are excellent quality and in most cases an exact match in length & construction
( MTD excepted )
Stens belts are slightly lower strength and all the same construction but a a fair bit cheaper so offer fairly good value for money.
Pix are one cheaper still and reasonable although I no longer stock them because I do not find they are value for money which reflects badly on my reputation.

Interestingly, there is an LTX1050 for sale locally; "has deck drive belt issues."

Have had our LTX1050 for several years and have done stuff with it that was not recommended for it and never had an issue with the belts until I screwed up replacing the deck one day and tore up the blade belt. That was the original belt and never broke just got chewed up a bit. Will see how long the replacement lasts.

Update: I finally got to the bottom of this issue. Apparently this is a known issue with this model, I went to my local Cub Cadet dealer to buy new pulleys; the told me to buy 759-05026 KIT: PUL:IDLR LOW CUT LGXT/SLXT. IT FIXED MY PROBLEM!!!!! This is what they have been doing to all of these models to fix the problem with the belt being thrown off. These pulleys are taller and deeper, the only thing I noticed with these is if you have the blades engaged in the number 10 position one of the pulleys rub a little on the deck hanger bracket. I just installed them as if they were the originals, same bolts, washers ect, in same order.

working on a LTX 1050 for a guy right now. installing a new crank seal and it still has the original belt with 642hours on it. you have to have something obviously wrong with the belt routing or pulleys. get us a pic of your deck so we can help you.......

What year was it manufactured? There were known problems with the 2011, 2012 model years. Scarry that a crank seal went out at 642 hours. I always wanted a Cub Cadet, this one is the worst lawnmower I have ever owned. I had a walmart Murray that lasted 15 years, I put 2 belts on the whole time I owned it. The tech at our local Cub Cadet dealer told me to make sure the deck level side to side, and about 1/8 inch lower in the front, I did all of that. I also replaced the idler arm, and the bushing that it pivots on. It has come off a couple times since then, but never come off during mowing, it will only come off when you first engage the blades for the first time of that mowing day, I guess when the belt is cold.

This particular problem is caused by insufficient tension or tension arm travel or belt being too long.
The work around ( not fix ) is to find the height that the belt runs closest to level from the engine to the deck and engage the blades in that position then change the cutting height you want.
A bit of a PIA but far less than jumping off and refitting the belt.
Check your owners manual as some decks require specific engine speeds before you engage the blades.
