Why did my troy bilt 2005 799 pony stop moving in drive? engine pulley smoking burned up the drive belt. replaced belt when i try to put into drive and engage clutch same results. moved transmission pulley by hand when belt was off tranny moved slightly. seems that transmission is locked or not enough tension on belts. triple checked oem belt numbers.
Transmission is lock up gears worn out probably do to lack of oil you can get rebuilt but it cost a lot

belts usually come off for a few reasons.
They become loose...stretch or the tensioner moves, Make sure that none of the tightening bolds are slipping. You can dab them with a bit of paint.
when the pulleys are not in alignment or crooked or bent. Eyeball the path from one pulley to another, also make sure the tensioner is in alignment and there are no other obstructions.
good, high quality belts are required, and they must be real drive belts...not regular v belts. If there is a way to watch the belt in operation you can usually see what's going wrong.
On my lawnmower I had to grind some metal away where the belt went from the motor to the transmission. Good luck

You turn the mower over, remove the blade with a 9/16 or 5/8 socket. There is a bolt holding shroud on, 3/8 or 7/16, there are two screws by the rear wheels, 7/16 that need to be removed. Once the shroud is removed, belt can be removed and new one put on.

Take the three screws out of the belt cover. One screw in behind each back wheel. The other is under the mower near the shaft to blade. Remove the tension spring off the transmission. Then remove blade and the cover comes off. You then can put the belt back on. Sounds like fun don't it!

If you didn't by the Troybilt belt, try that. I had the same problem with a Napa belt. Going into drive as soon as I grabbed the operator presence button, not coming out of gear etc. When I switched the the Troybilt belt, the problem went away.

Try taking the shroud off of the motor and and cleaning the magnets on the fly wheel. Also clean the two little prongs next to the fly wheel. You can also clean the end of the spark plug cable that hooks onto the plug. I use fine sandpaper or emery cloth.
Good Luck
