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.
