Exmark introduced two engines designed specifically for its zero-turn mower applications: the 708cc V-twin engine and the 452cc single-cylinder engine.
Both engines feature overhead valve designs, cast iron cylinder liners, oversized crankshaft bearings and triple-ring pistons.
708cc V-twin engine
The 708cc V-twin engine includes an air intake design aimed at reducing dust and debris build-up. According to the company, the intake system delivers more air to the engine for increased power and fuel efficiency as well as reduced operating temperature.
In addition, the engine features a vacuum choke override and a quick-drain system that allows users to drain oil without tools.
The company’s Quest E- and S-Series machines are the first to be available with this twin-cylinder engine.
452cc single-cylinder engine
The 452cc single-cylinder engine is designed for use with Exmark’s small zero-turn mowers.
The engine includes an optimized balance shaft design for reduced engine vibration and an automatic compression.
It also features full-pressure lubrication and a standard dual-stage oil filtration system.
The 452cc will first be available on the company’s 34-in. Quest S-Series machines.
