The drive belt is the topmost belt, next to the frame of the tractor. So jack up the front end, lower the deck and take a look at the engine shaft if there is a loose/broken belt laying up there. If so then you are right. You will have to remove the deck to replace the belt. There is a spring loaded tensioner, released by the brake pedal, so you will need a confederate to hold the pedal down for the last step of install. Begin by putting the belt around the big pulley on top of the transmission first, then the engine pulley. If the belt is in place then you most likely have a fried transmission and they are so expensive prepare to get another mower.

Why does my husqvarna riding tractor motion belt keep slipping off the pulleys?

They did not manufacture the pulley correct. The pulley lip is to short. What u need to do is bend the belt keeper so it just touches the belt on the idler pulley. I remove the pulley and keeper and give it a good bend. Then I adjust it into the correct position after reassembly. It doesn't have to rub on the belt.... just very close. That will do it.

After running husquavarna riding mower 23hp mower starts backfiring and ends up quitting. mower will start back up but die out again as descibed.

I had the same issue and after trying everything I tokk the gas cap off and noticed there was negative pressure in the fuel tank when I broke the seal... I'm pretty sure the gas cap was just too tight, I threaded it back on but did not torque it down and the mower is running fine.

Husquvarna hydrostatic mower won't move

Sounds like the belt going to the hydrostate broke. Or a key on one of the pulleys broke. The belt runs inside of the frame and is hard to see.
