have a 2008 walk behind 4 speed model 12A1867Q011 doesn't appear to be anything wrong with it except it keeps throwing the drive belt. has any one out there had any experience with these?

Inspect pulleys for wear, grease and or lube all moving parts. Replace belt with factory belt.


OEM Parts

Check pulleys to make sure none are lose or wobble.
Most common cause is a wore out belt.
Like mark said use OEM belt
