I have a Husqvarna YTH2348. A few weeks ago my drive belt slipped off the pulley on top of the transmission and got stuck between the pulley and the transmission. I replaced it and mowed the yard. The next week when I was mowing, the same thing happened. I saw no damage on the belt, so I put it back on and finished mowing. The following week I went to mow and found the belt was off again. I took time to fix it again. I made about six passes on the mower, and it has came off again. I feel that something is not right with the design or something is broke. Any help would be appreciated. I can't afford to work on the mower multiple times to mow one time.

Drive belt broken or slipped of pulleys, hydrostatic drive filter(s) plugged. Should be one or those, Roger. Follow the drivebelt with your hand (disconnect battery to be safe) and see if it hasn't slipped off the engine drive pulley, idler pulleys, or axle pulley. If you tractor is hydrostat, may be time to replace filter.
I fear that the belt is slipping in the pulleys, the clutch is very unlikly to slip as it is a metal to metal contact, i have never had to fit a clutch due to it slipping, the K970 went on from the k950 and had a poly v belt and pulleys, you can retro fit the the pulleys belt and blade shaft, the loading on the standard belt is very high especially when using a 16" blade.
i had a 2148. you remove the mower deck as the first step. feed the belt over the pulley on top the transmission, then put it over the engine pulley. then have someone push the clutch pedal in so the tensioner pulley moves, put the belt in the guide pulley and on the tensioner. release the clutch put the deck back on and you are good to go. notice there are little keepers welded to the frame for the front, engine, pulley and it is easy to mistakenly put the belt over them instead of under them.
a general rule is that a pulley shaped like a Vee takes the V of the belt whilst a pulley which is flat takes the flat back of the belt. if you bear that in mind you will not have a problem putting belts back on. also there is a little decal on top the deck showing how the deck belt and deck drive belt go.
either the drive belt which connects the crank shaft pulley to the top of the transmission pulley has failed, or the hydrostatic transmission has failed. the first is easy to spot, a broken belt, and fix; the second problem basically means you will spend more to buy a new transmission than another mower will cost.
When you raise the front or rear of the tractor, and push on the belt (engine off of course), is there a lot of play or slack in the drive belt. At this point from what I have read, the issue is the drive belt, and is slipping when in gear and when it heats up. The next thing to do would be to replace the belt, but I not sure if this procedure is an option for you. When you inspect the under side of the tractor, and inspect the moving parts and pulleys, if any of these components are in need of replacement, you will be able to tell by either rotating them manually or visually inspecting them. At this point due to the low hours, I suspect the drive belt is stretched out, and is considered a maintenance replacement part procedure.
You can replace the drive belt, and make sure the springs on the tensioner and clutch pulleys are good, but the belt itself has no adjustment. They stretch a bit with age, also not uncommon for the transmissions to go bad which means slow or no movement even though the engine runs normally.
Check your tensioning bracket, when parked and engine off, lower the deck, look underneath from the left hand brake pedal side and work the brake pedal by hand take notice of the bracket with two pulleys mounted on it that move with the brake pedal being pressed and depressed, if you have vertical? up and down movement opposed to horizontal fwd and back movement your bracket mount and or bushing could be worn out.. Mine was, and after replacement it was like the day I bought it new.
Hope you his helps..
Under the mower below the seat of the rider, at the rear of the tractor, look up and you will find the transmission there. There is a belt that runs on the pulley under there, and this belt can slip off when it gets worn or stretched. Sort of a tough spot to get to but, that is most probably cause.
Far as I know the warranties are not transferable. Some hydrastatic transmission fluid can be checked by removing the battery and underneath there is a place to put the fluid and to check it. But not all models or makes gives you this option.
i got the same problem the belt slips on the spin cycle i have replaced the pulleys the belt and the tensioner worked well for a week then back to slipping took the whole machine apart and found dryed up grease in the top seal and on the shaft cleaned it all of put new grease on worked fine for two months today same thing again took it apart and the shaft is all gross and stickye with dryed up grease i just like to know what grease a guy should use
