The Briggs & Stratton 19hp EX1900 Series is a genuine 540cc single-cylinder OHV engine designed for professional reliability, smooth operation, and long-term durability. Featuring a full-pressure lubrication system with an automotive-style spin-on oil filter and a Dura-Bore cast iron cylinder sleeve, this engine is built to handle the sustained demands of large-area ride-on mowing and commercial ground care equipment.

This variant features a 16-amp charging system — specifically suited to ride-on mowers equipped with an electric PTO clutch that requires a minimum of 15 amps. Briggs & Stratton's AVS anti-vibration system eliminates the side-to-side motion inherent in traditional counter-rotating balance systems, delivering noticeably smoother, quieter operation throughout extended mowing sessions.

Supplied with a Super Quiet muffler fitted as standard, a float-feed carburettor with integral fuel pump, and maintenance-free Magnetron electronic ignition. A direct replacement for most ride-on mowers on the market. Backed by a 2-year consumer warranty (1 year commercial use).
