Designed from the ground up as a zero-turn mower engine, the new Exmark 708cc V-twin engine introduces a number of new performance and serviceability enhancements to the marketplace. The innovations bolster the professional-grade performance and durability of Exmark's small and mid-sized zero-turn riding mowers. The standard V-Twin engine is on Quest E-Series mowers with 34- and 42-inch cutting decks, and Quest S-Series machines with 50- and 60-inch cutting decks. The commercial version of 708 V-Twin is available on all Radius E-Series and S-Series machines. Radius S-Series models also come standard with the heavy duty cyclonic air filter.

The Exmark 708cc V-twin engine features a vacuum choke override for increased startability and smoother running at start-up. A standard quick-drain system eases oil changes by offering the ability to drain oil without tools. The long drain hose eliminates the messiness traditionally associated with draining the oil from the engine, and the design dramatically reduces the time required for routine oil changes. The 1/4-turn twist-lock dipstick design makes oil level checks quick and easy. Exmark's revamped Quest E- and S-Series machines are the first machines to be available with Exmark's new twin-cylinder engine. The innovative air intake design reduces dust and debris build-up with a constant flow of pre-screened air. The design of the air box cover and air filter virtually eliminate the possibility of an incorrectly installed filter allowing engine-killing dust and debris into the engine. Combined with a standard dual-barrel carburetor, the intake system delivers more air to the engine for increased power and fuel efficiency, and reduced operating temperature. Engine will be standard on Quest E-Series and Quest S-Series mowers.
