Which belt is coming off the transmissions drive belt or the deck belt? Are the belt guides in place and adjusted so the belt can't come out?

Customer: replied 6 months ago.
Transmission drive belt
Customer: replied 6 months ago.
the belt guides are in place and belt is tight.
Expert:  Curtis B. replied 6 months ago.

With engine OFF, is the belt tight? The tension spring has to keep the belt tight!

Customer: replied 6 months ago.
The spring is also tight it throws the belt off when I move the levers to go forward or reverse.
Expert:  Curtis B. replied 6 months ago.

With engine running, is the belt bouncing around? Sounds like the belt is not on properly. You say you replaced the belt and the clutch? Clutch is for the deck,???

Customer: replied 6 months ago.
The belt is on properly the reason I changed it was because the factory belt fell off n the mower would not move forward or reverse.but it keeps throwing it off that's why I am asking for your help

Where is the front drive pulleys belt guide? Is it there. The belt should not change its route or load when you move the levers !
