WoodMaxx FM-54 Y-blades vs Farmry LFP47: two approximately 47-inch fixed flails
The FM-54 · Y-blades and LFP47 cut nearly the same width: 47 and 47.2 inches. Their power requirements are very different. WoodMaxx’s current manual specifies 15–25 PTO hp for Y-blades; Farmry lists 25–45 HP without defining the basis. Compare cutting-height needs and the exact configuration before interpreting the $791 observed price difference.
