Briggs & Stratton Commercial Power unveiled a new zero-turn mower engine—the Vanguard V-twin 810cc Engine, available in 24 to 26 gross horsepower models with engine displacement of 810 cubic centimeters (cc).
“For the ZTR market, contractors want durability, reliability and most of all displacement,” said Dan Roche, marketing manager of commercial power for Briggs & Stratton, at a launch event and plant tour for the trade media in Auburn, Ala., in September. “We believe 810 cc is the optimum.”
There has been “displacement creep” in the ZTR engine market—to the tune of about 50 cc over the last four years, but increasing displacement often means increasing the footprint of the engine, Roche said. That’s not the case for this model.
Briggs officials were tight-lipped about which mower manufacturers will debut these new engines, except to say there are “launch customers” lined up that will be introducing mower models featuring the engine in late 2013. However, Roche said mowers with cutting widths between 54 inches and 60 inches dominate the ZTR market, and this new engine fits those sizes well.
The new engine carries the Vanguard three-year commercial warranty.
This introduction marks a new “mid block” category for the Milwaukee-based company, Roche said. The Vanguard 810cc falls between the company’s V-Twin Big Block engine line, which includes a range of engines from 25 to 35 gross horsepower and features engine displacements as high as 993 cc, and its “small block” V-Twin line with gross horsepower ranging from 13 to 23 and displacement in the high-400 cc to low-600 cc range.
