I have a 46' deck riding lawn mower. Every time I disengage

Customer Question

I have a 46' deck riding lawn mower. Every time I disengage the blade my belt would slip off so I got a new belt hoping that would fix the problem but it didn't. Is there any way I can tighten up the belt?

Belt is tensioned by spring, is spring in place? And what pulley does it come off of? There has to be a belt guard, that will keep belt from coming off the pulley. it may be missing or bent to far from the pulley, allowing belt to slip out.

All the belt guards are in place and in good shape

Both 45 and 61's are close enough to the pulleys to not let belt out without moving them? See the above link. And the two springs are in place? Can you determine which pulley it is coming off of?
Customer: replied 1 year ago.
It's coming off the 2 middle pulleys and the very front one. It doesn't come off the pulleys that control the blade

I'm not for sure about the springs I'm at work right now but I know for sure it's coming off those 3 pulleys. It's mostly coming off the front toward the engine
Expert:  Curtis B. replied 1 year ago.
Front drive pulley at the engine end, has two bolts/rods that have t keep the belt on. One on each side of the pulley. Be sure they are almost touching the pulley.

Cause I can pull the belt off pretty easy on the front pulley and the blade pulley
Expert:  Curtis B. replied 1 year ago.
You should not be able to remove either one without moving the belt guides! I think belt guides need adjustment.
Customer: replied 1 year ago.
How do I do that?
Expert:  Curtis B. replied 1 year ago.
tap them to move them closer or loosen nut holding them and move them closer to the pulley.
Expert:  Curtis B. replied 1 year ago.
Closer the better, as long as they do not touch the pulleys
Customer: replied 1 year ago.
What about the front one. It's also really loose around the blade pulleys but they don't come off
Expert:  Curtis B. replied 1 year ago.
#25 is the belt keeper for the front engine pulley. see link.

And what if this doesn't solve the problem?
Expert:  Curtis B. replied 1 year ago.
If the belts can be removed now, without effort, the guides are not close enough. I think it will take care of the problem.
