You do not say which size cutting deck you have. I will be writing about the 48", 3 blade cutting deck
The belt on this deck is self tensioned. The tension is provided by a spring attached to a moveable pulley on the deck. When the belt is in place you can manually force this pulley forward/backward and it will release the tension.
If the belt is off track, place the belt back around all the pulleys in the correct path, lastly force this spring loaded pulley forward/backward (depending on your deck, the direction is not important, the tension is) to get the belt around the pulley. If the belt is placed correctly, when you release the spring loaded pulley it will properly tension the belt.
Typically, these belts should not be jumping off. If yours is coming off frequently the belt may be worn. When they wear they get quite a bit longer, then the tension pulley cannot apply the correct tension. Rarely does the tension spring have to be replaced.
The other problem that causes belt jumping is worn spindles and stationary pulleys. The spindles are the most likely to need replacement. You can buy excellent replacements for JD spindles on Amazon for very reasonable prices. The following spindles are super replacement spindles for the 48" deck. They may very well be the same for smaller and larger decks; I have not researched that. Just search Amazon for Silver Streak # 285851.

(Simple answer)Hydrostatic drive machines have a setting that allows you to push them. machine won`t move if this is engaged.
Also If park brake is on. Otherwise check drive belt has not snapped is loose or broken. Jack machine up and see if wheels will drive without weight of machine.
If traction drive belt is turning you should check the input drive shaft on top of trans to see if it is turning as well,Traction drive belt is suspect but could be a stripped out input shaft pulley.Make sure the machine tow lever is not pulled out,rear of machine by tow hitch.Also pull rubber caps off of both axle ends to see if one the axles is turning free inside of rim,if so remove wheel and replace axle key.
I have googled LT155 and came upon john deere LT155 lawn tractor(noncurrent). It took me to John Deere's site. I put in your model number and it had several catagories. I would try the alphabetical list, go to B and look for traction belt. Good day.
u can change belt yourself need belt size and have to remove cutting deck but check belt tension first if loose with brake off belt stretched out and slipping needs replacement
