The FT730V-EFI is the first engine from Kawasaki to employ Vortical Air Filtration (VAF), an air-intake methodology designed to combat many of the ongoing issues faced by lawncare professionals as well as homeowners.

VAF includes inherent debris-cleaning effects. The pre-filter and filter can run for up to 50 hours before requiring cleaning. The VAF technology incorporates air intake methodology that is engineered to focus on getting clean air into the engine without also introducing external debris, such as loose grass clippings.

This advanced, high-efficiency air intake system uses centrifugal air movement to move heavy grass, dust, and debris away from the air filter, the ejects accumulated debris out of the engine through a duckbill debris ejection valve.  Once the ejection process is completed, only fine dust is left, which is easily trapped in the filter.  ]The benefits of this system are many, with cleaner intake air contributing to longer engine life, reduced maintenance, and improved performance. 

Grass entering the cooling air path system under normal mower use is easily removed through the large clean-out ports located over cylinder heads.  The cover for these clean-out ports is neatly integrated into the VAF cover.

Kawasaki’s new FT730V-EFI system employs an integrated e-governor (eGov) that immediately adjusts engine power-to-load for maximum cutting power at higher speeds, cleaner mowing when units are used in heavy turf, as well as minimizing the need for re-cuts.  The same EFI system is currently available on three  other Kawasaki engine models from the company’s FX and FS product lines. 

Kawasaki’s single, sealed ECU—the heart of the company’s EFI system—is sufficiently protected to avoid exposure to weather, dirt, and vibration.

The open loop design, which avoids the need for an oxygen sensor, maintains low engine temperatures, which in turn helps reduce oil consumption and contributes to a longer overall engine life.
