The Scag® Turf Tiger™ features a Kawasaki® 791DFI (digital fuel injection) engine option. Over the past decade, the FD Series of engines by Kawasaki has earned a reputation as a serious, professional-grade powerplant. This highly fuel-efficient DFI engine generates a substantial torque. This extra performance can really be appreciated when cutting wet, heavy grass or when using an accessory such as a grass-collection system. Liquid-cooled engines typically last longer than air-cooled engines, providing additional value. Fuel injection delivers increased fuel efficiency and additional benefits like choke-free operation and easy cold-weather starting. These are high-performance engines and deliver lots of horsepower to get the job done faster and easier. Other features include: Multi-port, digital fuel injection. Liquid-cooled. Overhead V-valve. 90-degree V-Twin. Pressurized lubrication. Electronic spark ignition. Compact electronic control unit. Choke-free operation. Water-temperature sensor. High-pressure electric fuel pump. Cast-iron cylinder liners. * Note: Engine specifications based upon manufacturer-supplied information.
