Raptor SD mower deck belt

Rumple

Forum Newbie
Hi All,
I've got a relatively new to me Hustler. Raptor SD with a 60" mower deck and i'm still learning the ins and outs of the machine.
I just broke my second mower deck belt of the season, getting about 10-12 hours on a belt. Is this normal? My last mower was a John Deere and I'd typically get 3-4 seasons on a belt. I've got a big rural property so go through about two tanks of fuel for a single cut and don't have the time to cut it until grass gets 4-5 inches high...the machine works hard. That said though so did my JD and I never went through belts as fast as I do on the Hustler.
Further to the above, can anyone recommend a brand of deck belt that gives the best service life?

In order for the folks here to help, supplying your model number and serial number would be great.
There are several reasons for your belt to break.
Bad pulleys or spindles. Grass or twigs getting into the pulleys. Wrong belt. Belt tension not right. A sharp place or gouge in a pulley. ETC.

Good point. The bearings are noisier than I like but there is no detectable slop, I'll probably change them out next year before the season starts.2026-09-2614.57.552765003054750589653.jpg

Chinese made Amazon or FleaBay belts are a gamble.
Make sure your pulleys all spin freely without noise.
Make sure your spindles don't have slop up and down and side to side without noise.
Make sure all pulleys are level with one another.
Keep the top of the deck clean.
