Does anyone have a Manual (Maintenance and IPC) for a Haban Flail Mo? Both the drum bearings failed on mine. I have dissasembled the unit (what fun that was) but would like to get the bearing P/N's. The bearing for the non-drive side is pressed into a housing and the drive side is pressed onto the shaft. There is a spacer shaft ovder the drum support shaft and it's quite a design, very robust. The poor old sealed drum bearings just couldn't hack industrial mowing after 40 years and died after about 3.5 acres of mowing.
