ExMark drive belt

[Firefighter1428]

I have a 2004 Ex Mark Metro, I've been having problems with my drivebelt falling off. This problem only happends after the mower sits, I usally find it every morning with the belt half off,Every morning when I go to put it in gear, it never does it while cutting grass, only when sitting for afew hours. I have a new belt on there and Im still having the same problem. Is anyone else having the same problem or does anyone know why this is happing?

Thanks

That little silver sleeve that fits right behind the belt that catches all the mud and grass...well look at it. One side(side facing the belt) is worn down due to use and it allows the belt to move. Loosen it, spin it around some...problem solved. I found this out the hard way and now for more than a year...no more problems.
