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

Fuel Type


V-Twin OHV Technology

V-Twin engine design provides better balance and allows for increased power. OHV technology optimizes performance for a longer engine life and enhanced fuel economy.

Electronic Fuel Injection

The Vanguard V-Twin EFI engines feature an automotive-based, closed-loop EFI system that delivers easier starting and improved performance, with fuel savings of up to 25%*

* Closed-loop EFI system fuel savings may vary based on cutting conditions and other factors.

Smooth Easy Starting

The mechanical compression release eases the starter to crank the engine. Including battery ignition with variable timing as part of the EFI system, in addition featuring the industrial grade solenoid shift starter. The result is a smooth easier starting and longer starter life.

Maximum Durability

Engine block designed to provide superior durability. Cast iron cylinder sleeve adds integrity and durability that withstands wear and abuse while providing improved oil control. Durable head and valve train design, including valve and seat materials uniquely matched to run under the most severe conditions.

Improved User Experience

Engineered design for minimum vibration leading to better user comfort. The addition of the dynamically balanced crankshaft and flywheel plus the automotive grade pistons results lower noise, vibration, oil consumption, emissions and wear.

Extended Engine Life

Maximum lubrication and critical engine components protection. The spin-on filter keeps oil cleaner for an extended engine life.

Superior Air Management

Five inch centrifugal multi-stage air cleaner for maximum engine protection, especially under dirty and dusty conditions. The innovative debris chopper fan significantly reduces engine oil and head temperatures.

Oil Guard™ (Optional)

The Oil Guard technology exclusive to Vanguard extends oil maintenance intervals from 100 to 500 hours, reducing significantly the time and costs associated with oil maintenance -60% savings* on oil maintenance- and providing enhanced oil protection.

*Per season, per unit. Cost savings based on standard oil maintenance with 100 hour interval versus Oil Guard System 500 hour service interval.

Global Warranty Coverage

Three year limited commercial engine warranty for all applications.
