How long do you find deck belts last?

Well grabbed another OEM(91$ canadian with tax !!) today , plus ordered a cheapy as a spare. No marks anywhere on belt. Deck always clean and all open lawn, so nothing would have got in belt, or hit anything. Went over is super close....everything is mint. Did clean up pulleys with some fine sandpaper for good measure. Maybe just a bad belt...guess we will see in 70 hrs....lol Thanks folks

For 90 bucks, I would have expected to see some kevlar in that belt and I don't see any
 
I have a 23hp/46in Snapper rider. Deck belt broke tonight. Belt is only about 2.5 years old, 70hrs on it. Belt still looks new, but pulled apart. Was an OEM belt. Is that typical life? I'm a maint. freak, and all pulleys etc are mint. This is the first rider I have ever used so wasn't sure.
I am now reaching 200 hours on the factory belt of my John Deere D140. It popped off once about two operating hours ago. I popped it back on and it seems to be working well.
 
My buddy has a exmark he mows with daily , 850 hours last time I checked , original deck belt.
I don't have near that many hours on my mower , so I can't brag about the belts yet.
 
I believe there was a design defect with some of the Snapper decks. I have a 2012 Snapper LT24460 (24 hp, 46 inch cut) with 220 hours on the original belt. The tractor has been flawless. But a friend had the next smaller Snapper lawn tractor and it chewed up several deck belts. The Snapper dealer claimed he was driving too fast through heavy grass. Not.

Everything is mint, so I'll see how this one lasts.
 
Got a JD L100 for free. Rebuilt the deck w/amazon cheap parts. Couldn't keep the deck belt on erratically when disengaging, same with a Tractor Supply belt.
I bit the bullet for a OEM JD belt after reading some praises on here and zero issues for 2 yrs now on that and no issues when disengaging at any engine speed.
Sometimes you get what you pay for.

This. I just replaced the belt on my 2003 JD L110 equivalent (Scotts branded) with a JD belt after a no name replacement belt only lasted 2 seasons before breaking. The original JD belt was still working 2 years ago when I replaced it and would have probably outlasted the piece of junk I replaced it with. Lesson learned!
 
I mow once a week for just over 1 hour, for about 7 months out of the year,(or whatever 300 hours since 2010 works out too) and once or twice in the winter chopping leaves.
Using OEM cub cadet/MTD belts, i replaced them every year cause by the end of the season, they were sitting deep in the V grooves of the pulley and hopping off and or slipping.... I started getting my belts from Stens now, and holy cow....im just over 2 seasons on the stens belt and it's still looks good with not much wear.
 
My original JD belt had about 300-400 hours and was still working.

My dad has a couple of cub cadets and it seems he has had his share of belt issues.
 
Ztr drive belt from 2011 looks great. The blade belt was replaced once after heavy debris and locked blades a couple of times started to fray it. Using oem ariens.
 
I prefer OEM belts, especially on mowers with a complex belt routing system, or one that requires complete removal of the deck to replace it. My John Deere's original mower deck belt went ~600 hours. I replaced it because I was doing the idler pulleys as well, since one of those failed.
 
I have a couple of over 20 year old Craftsman LT1000s. both with over 700 hours. As far as I can tell original drive belts. The Deck ones. LOL not so much. I think I ended up doing those every few years. Not enough time on the Cub Cadet XT2 to tell yet.
 
For 90 bucks, I would have expected to see some kevlar in that belt and I don't see any
?? The non-kevlar usually look like smooth black rubber on the outside, not cloth as pictured. Granted, a penny pinching design could use some other fiber instead of kevlar.

One of the deck belts on my ~20-something y/o mower broke ~4 years ago, 2nd original belt is on it still but have replacements ready.
 
Little sticks in the yard caught the deck belt on my Troy Bilt today twice. Made the belt come off. I am going for a new one now. Been on there about 3 years.
