20,9 Gross kW* EFI

20,9 Gross kW* EFI


At an optimum 810cc, these commercial-grade engines establish a new standard for zero-turn engine displacement. For turf professionals, that means higher performing, more efficient, more powerful and, ultimately, more profitable commercial cutting. With the addition of optional closed-loop EFI, these engines are redefining commercial mower efficiency even further. Combined with 810cc performance, this automotive-based system can elevate your fuel savings by up to 25%† versus carburetted engines. When you consider how many man-hours a crew can log in a season, your savings could be in the thousands.

Typical Applications Include: Commercial Mowers
