Hey guys, thought I would share this info:

The New Vanguardâ„¢ 31 HP Air-Cooled V-Twin Delivers Optimum Power & Performance

The leader in air-cooled gasoline engines has powered it up once again with the industry’s FIRST 31 HP Air-Cooled V-Twin. This highly productive powerhouse is ideal for a broad range of commercial applications and delivers all the performance advantages you value most.

Powerful Performance

V-Twin/OHV technology offers superior balance and low vibration, which saves wear and tear on components and equipment.
Robust 895 cc (54 cubic inch) displacement.
Increased horsepower-to-weight ratio contributes to engine efficiency, reduces compaction and makes handling easier.
Innovative intake and exhaust system results in a quieter-running engine.

Rugged Durability

Advanced Debris Management System allows the engine to run cleaner and cooler, which enhances durability and performance. Components integrated into this innovative system include:
Rotating steel screen that aggressively chops debris and chaff into smaller pieces which easily pass through the engine’s cooling system.
Labyrinth between the rotating steel screen and blower housing helps to prevent debris from entering the engine.
Cast iron sleeve assures longer engine life and improved oil control.
Industrial grade solenoid shift starter assures quick, reliable starts.
Replaceable ball bearing construction.
Five-inch centrifugal multi-stage industrial air cleaner provides maximum engine protection, especially under dirty and dusty conditions.
Large-volume muffler with specially baffled chambers minimizes noise.
Buyer Protection Package that provides the peace of mind of a two-year limited engine warranty, plus a lifetime Magnetron® ignition warranty.

Increased Productivity

Full-pressure oil lubrication system with spin-on filter works to keep oil cleaner, which reduces maintenance and extends engine life.
Low oil consumption for longer running times between scheduled maintenance.
Foam pre-cleaner traps large debris before it can clog the filter element and rob the engine of needed air.
Low fuel consumption results in less frequent refueling stops.
Low noise and smooth-running operation help to maximize operator productivity by minimizing fatigue.
