I have a Husqvarna YTH24v48 riding mower, and it has been quite good. However, a few weeks ago, it broke its deck belt...no big deal, this happens, over time. Before I replaced the belt, I checked everything out and found what I consider a Design or Manufacturing Flaw. There is an idler pulley, PN 532197379 sitting between the center spindle, and the RH spindle, mounted onto a "fitting" which is welded to the deck, and held in place with a 3/8-16x2 1/4" bolt...PN 817490636. The problem is that this "fitting" in only about 1/8" thick, which allows only 4 or 5 threads of the bolt to be wound in. On my mower, the idler pulley was quite loose, and the bolt had actually started to bend. This allowed the belt to flop around, and wear prematurely.
I went to the hardware store, and bought a 3/8-16x2 1/2" bolt, and a matching locknut...about 75 cents, and mounted the pulley with these new parts....adding a flat washer under the bolt head so it wouldn't damage the pulley bearing. There is Plenty of room under the welded mount to add a locknut...although it is a bit tricky getting the nut started in such a cramped area. A few turns with a socket and a wrench now gives the pulley bolt a far more secure mount. Since the "fix" I have mowed several times, and checking the belt area after each mowing shows No signs of the pulley loosening, or belt wear/damage.
This type of deck appears to be commonly used on Husqvarna, Craftsman, Poulan Pro, and probably other brands. If you have such a deck, you might save yourself lots of time and money by checking this area out, and making this quick/cheap fix. IMO, the manufacturer has created a "weak spot" that certainly does not contribute to the Quality of their product. Adding a 25 cent locknut might save a breakdown in the middle of mowing, and $25+ for a new belt.
