Quest S-Series
For homeowners looking to upgrade to Exmark's best residential zero-turn mower, the Quest S-Series delivers commercial-grade performance at an affordable price. With the ability to clear more than 3 acres of lawn per hour, S-Series residential zero-turn lawn mowers make quick work with forward ground speeds up to 7 mph. Factor in Exmark's signature zero-turn maneuverability, and the S-Series offers tremendous value with professional mowing results.
The S-Series residential lawn mower boasts a massive 54-inch welded steel mower deck and cutting width powered by a Kohler® or Exmark engine, which features a heavy-duty hydro gear system. Every Quest arrives standard with commercial-grade wheels for precise cutting and professional-grade traction to complement the 24 horsepower engine.

Quest S-Series Features

Engine Protection
Standard, rear engine guard provides increased protection of critical engine components.

Fuel Tank Capacity
A single, 3.0-gallon tank with one fill location keeps you mowing longer with fewer fill-ups.

Commercial-Grade Tires
Standard on Quest mowers, the commercial-grade front caster tires and rear drive tires provide increased traction for superior handling.
