I just purchased a nice LA150 with a 54 inch mower and want to get a bagger/Power Flow. A Facebook posting for a PWRFLO 54MOW Serial Number 1M00PFCHVBM090381 stated it would work on a LA150 (and LA175), but when I called the local JD dealer they said it was for a Garden Tractor not a Lawn Tractor. Does this sound correct. I have searched online in several locations to see what bagger/Power Flow will work, but am striking out. Can anyone help? Thanks!
