Farmer-Helper FH-BX42 vs WoodMaxx WM-8H: 4-inch gravity or 8-inch hydraulic feed near 19 PTO hp
A tractor like the Kubota B2401 (19.2 PTO hp) is inside both chippers, but in very different places. FH-BX42 runs from 15 PTO hp, so it has margin; WM-8H starts at 19 and WoodMaxx ties its full 8-inch capacity to 50. The choice is a simple, light gravity chipper against a larger hydraulic-feed machine at the bottom of its range.
