WoodMaxx FM-62H vs FM-78H hammers: 55-inch or 70-inch cut?
Choose between a 55-inch and a 70-inch cutting swath, then check the exact hammer configuration. FM-62H specifies 24–45 PTO hp; FM-78H specifies 30–65. The larger mower also documents a Category 2 mounting route with bushings. Both require rear hydraulics, and their conflicting weight records need resolution before the price or width decides the purchase.
