With a 993 cc, EFI Vanguard Big Block air-cooled, horizontal-crankshaft engine, Model 937 EFI FrontMount works with the fuel efficiency of fuel injection. The G3 hydrostatic pump-and-wheel-motor system is powered by a flat, ribbed serpentine belt and a 14.4-gallon fuel capacity. The PowerFold Electric Deck Lift raises the PTO-driven, 5.5-inch-deep DuraMax 61- and 72-inch cutting decks to a near vertical position for underside access.
