SImplicity 7117 hydrostatic with 48" deck throws OEM belt
After a great winter of pushing snow I put the mower deck back on and found it was throwing the belt. (This started at the end of last year so I expected it this year ) I replaced the mower deck belt with an OEM belt, and it simply won't stay on. As soon as I hit almost any grass the belt goes right off. All three flywheels and the tensioner arm seems to spin free and I can't see anything that is really adjustable, so I am not sure what else I should try to do. Are there any tricks, tips, adjustments that I am overlooking? I removed the guards and watched it and I can't tell what is making it pop off. Do I need to replace the tensioner spring maybe? Thanks all. I love this place.
