Demanding applications like commercial turf, marine, construction and landscape/agriculture have no time for downtime. That's why we engineered our lineup of Vanguard BIG BLOCK™ V-Twin vertical shaft gas engines to handle the toughest jobs, giving you dependable power, performance and reliability. The BIG BLOCK is reborn with updated cylinder heads, improved cooling fins, and better air flow to help it run up to 60 degrees cooler*. The new design also features a stronger starter motor and upgraded wire harness for more reliable starts and durability in commercial use.
Electronic Fuel Injection and Electronic Throttle Control (EFI/ETC), offered on many models, enhances fuel efficiency reliability while adding responsive performance.
The optional Vanguard Oil Guard™ System extends oil life for savings of up to 60% on maintenance costs** — a big benefit for zero-turn mower engines. Compared to other V-Twin lawn mower engines, it lets you go five times longer between oil changes, while still keeping the oil clean to protect your zero-turn engine.
