Features:

Kai Air Filter Included

• The Kawasaki FH580V-GS21-S comes standard with a factory-installed KAI-grade air filtration system, specifically engineered to meet the extreme demands of professional landscaping. This premium filter features a high-capacity design that provides an enhanced barrier against fine dust and airborne debris, ensuring that only purified air reaches the combustion chamber even in the most punishing, high-chaff environments. By including the KAI-spec filter as standard equipment, Kawasaki ensures your 19 HP engine maintains peak respiratory health, preventing premature wear and preserving maximum power output throughout its service life.
  

Muffler (oil filter side) included

• The Kawasaki FH580V-GS21-S includes a factory-integrated muffler, specifically oriented toward the oil filter side of the engine for a streamlined and compact installation. This heavy-duty exhaust system is precision-engineered to provide superior noise reduction and tone quality without compromising engine backpressure or power output. By arriving pre-installed on the oil filter side, it ensures proper heat shielding for surrounding components and simplifies the repowering process, allowing for a clean fit within the mower's engine deck while maintaining easy access for routine filter maintenance.
  

Clutch Coil Included

• The Kawasaki FH580V-GS21-S comes equipped with a factory-installed clutch coil, providing the essential electromagnetic component needed to engage your mower's PTO system. This genuine, high-output coil is precision-wound to ensure a strong, consistent magnetic field, allowing for smooth and reliable blade engagement even under heavy startup loads. By including this component as standard equipment, Kawasaki eliminates the need for separate sourcing and ensures perfect electrical compatibility with the engine’s charging system, streamlining the installation process and reducing overall setup time.
  

Fuel Pump Included

• The Kawasaki FH580V-GS21-S features a factory-installed, high-reliability fuel pump, ensuring a steady and consistent flow of fuel from the tank to the carburetor. Specifically calibrated to match the engine's fuel demands, this integrated pump maintains optimal pressure even when operating on steep inclines or in high-heat environments where vapor lock might otherwise occur. By including the pump as a standard component, Kawasaki guarantees "plug-and-play" compatibility, removing the guesswork of aftermarket plumbing and ensuring your 19 HP KAI engine receives the precise fueling required for peak performance.
  

Recoil starter

• The Kawasaki FH580V-GS21-S features a heavy-duty recoil starter system, providing a dependable manual backup to ensure your equipment is always ready for work. Engineered for maximum durability, the pull-start mechanism utilizes a high-tensile starter rope and a rugged internal pulley system designed to withstand the rigors of daily commercial use. This "easy-pull" design is perfectly synchronized with the engine’s automatic compression release, significantly reducing the physical effort required to turn the engine over, and offering peace of mind that you can get the job done even in the event of a low battery.
  

PTO Size: 1" x 3- 5/32"

• The Kawasaki FH580V-GS21-S features a standard 1" diameter by 3-5/32" length PTO (Power Take-Off) shaft, providing a versatile and heavy-duty connection point for your mower’s drive system. This precision-machined vertical shaft is engineered for high-torque transfer, ensuring a secure fit for your electric clutch or drive pulleys. The specific 3-5/32" length is a common commercial standard, making this engine an ideal "drop-in" replacement for a wide variety of zero-turn mowers and wide-area walk-behinds.
  

Overhead v-valve

• The Kawasaki FH580V-GS21-S utilizes an overhead v-valve (OHV) design, a high-efficiency configuration that places the valves directly above the piston for a more direct intake and exhaust path. This "V" orientation optimizes the combustion chamber's shape, allowing the engine to breathe more effectively and produce more power per cubic centimeter. By improving thermal efficiency and airflow, this design ensures the engine runs cooler and maintains a more consistent power band, even during high-demand commercial mowing applications.
