Question about Husqvarna Riding Lawn Mower Yth24v48ls 48 Inch Cut
Pulled my mower out today to change the plugs, oil/filter and air filter. Drove around the yard to warm it up and as I approached the spot where I do maintenance, I noticed it wasn't pulling as hard and seemed to slow down or slip but it passed without incident. I shut it off and did all the maintenance tasks, Started it back up and everything checked out fine. When I sat in the seat and tried to get her to move forward, nothing. Pressed the forward petal and released and then tried reverse, still nothing. Shut it down and got off to check the rod spring bypass and make sure she was fully seated, disengaged and then re-engaged. Rocked her forward and then reverse. Got back on, started up fine and pushed the forward petal and she moved 3 feet as normal then I hear what sounded like gears grinding but only when I try to move forward or reverse. The deck was turned off the whole time so I checked for the noise with the engine running while not moving and the blades started up and ran just fine, no noise. When I pressed the forward petal, the grinding started again but she started moving and kept going with the noise onstant. Stopped and got up under as far as I could see but all looks "normal" as much as I can see. The drive pulleys I can reach all felt attached and solid, no wabble, and the drive belt was seeming tight. Got back on, moved forward and the noise started again, so I put my foot on the brake petal lightly while moving forward and it seemed to quiet the grinding noise slightly. If I pressed too hard, she'd start slipping and loose power but if I just rested my foot on the brake petal, it would cut the noise almost in half. The noise seems to originate from directly under the foot rest area. Never had this kind of problem before on my 48" or my 46" Husk's. Any ideas? Visibility is limited as is access to the drive belt and those pulleys.
Check the bolts on the rear end see if there ripping out of the metal if so the rear end is twisting causing the belt to come off the rear causing the belt to pop off the belt Is probably under the pulley and when you push the brake pedal it release tension off the belt

If the machine has been sitting idle for a period of time it is probable that the cutter spindles have failed / rusted bearings. They suffer from wet grass/ water seepage when working and when let stand idle for a time will rust up the balls in the bearings. Loosen the drive belts and see if the cutters can be turned freely by hand .

Not sure what is going on here, these machines do not have a clutch as such, it will be a idler pulley that is pulled onto the back of the belt to tention it thus taking the drive to the hydro unit, so it may be a simple idler pulley replacment, or slave pulley replacement, with the hydro in neutral have somebody sit in the seat and work the pedal whilst you look under neath and watch what is happening.
