The Kawasaki FR600V-FS00-S is an 18HP, 603cc V-Twin vertical shaft engine designed for premium residential ride-on mowers and light-commercial mowing equipment. Built on Kawasaki’s proven FR-Series platform, this engine delivers smooth operation, dependable starting, and strong low-RPM torque for consistent cutting performance.

Featuring a 90° OHV V-Twin design, the FR600V offers balanced power delivery with reduced vibration. Its pressurised lubrication system, cast-iron cylinder liners, and durable air-cooled layout ensure long service life and reliable performance in tough Australian mowing conditions.
