@GIE-EXPO: Briggs & Stratton Unveils Oil Guard System

Briggs & Stratton has introduced the Oil Guard system for select Vanguard V-twin engines. The system is available as an option on 2017 Ferris on its commercial zero-turn riding, stand-on and walk-behind mowers.

In an effort to take the most significant part of regular engine maintenance out of the equation for commercial cutters, Briggs & Stratton is launching Oil Guard, a new system that the company said will allow the average commercial mower five times more operating time between engine oil changes and reduce oil-related maintenance costs by 60% or more. The system is being show to the public for the first time at the GIE-EXPO in Louisville, Ken.

The Oil Guard system will be initially applied to the company’s Vanguard 810 and Big Block V-twin vertical-shaft gasoline engines with electronic fuel injection (EFI) as well as the carbureted version of the vertical Big Block V-twin. For the 2017 model year, those engines will be offered exclusively by Ferris as an option on its commercial zero-turn-radius ride, stand-on and walk-behind mowers.

“Our goal with Vanguard engines is to provide the power and productivity our customers need to complete any job,” said Rick Zeckmeister, vice president of marketing at Briggs & Stratton. “We believe Oil Guard has the potential to change the industry by offering significant time and dollar savings. Nothing else is even close. “Some of our more experienced sales managers and some sales managers we’ve talked to are calling this game-changing.”

While game-changing is often in the eye of the beholder, it’s hard to dispute the fact that the Oil Guard system is designed to offer some startling benefits, the biggest being a 500-hour oil change interval — the typical interval being approximately 100 hours — along with enhanced engine protection, faster and easier oil changes and reduced overall downtime. “

At its most basic level, the Oil Guard system is a combination of design changes to the oil system of the Vanguard engine coupled with a 5 qt. remote aluminum oil reservoir. The engine modifications include the addition of a dry sump and an oil scavenge pump driven off the engine camshaft that works in tandem with the conventional crankshaft-driven supply pump, along with a check valve that controls the oil flow.

The fabricated-aluminum oil tank that includes a ringless oil dipstick, a wide-mouth oil tank cap and an automotive style filter that cleans the oil as it is returned to the tank. The filter is 82% larger and 80% more efficient with twice the dirt-holding capacity as the filter used previously, the company said.

Briggs & Stratton estimates that the use of the Oil Guard system will provide the average commercial cutter a savings of more than 60% of the normal costs associated with oil and filter changes.

The Oil Guard system will be covered under Briggs & Stratton’s three-year limited commercial warranty that comes as part of the 810 EFI and Big Block engines. While it will be available only on Ferris machines next year, Oil Guard is expected to be available to other manufacturers for the 2018 and 2019 mower model years and may be expanded to other commercial engine market segments as opportunities present themselves, the company said.
