MILWAUKEE, WI (October 22, 2018) – Vanguard® is excited to announce the expansion of its groundbreaking Oil Guard™ system to Spartan Mowers. The innovative Oil Guard system launched in 2017 on the Ferris® mower line and has since proven itself as a reliable solution in the field.

“Oil Guard was developed to reduce downtime associated with engine oil maintenance,” said Christine Davison, senior marketing manager, NA Engines and Power, Briggs & Stratton. “The Oil Guard system has been incredibly successful in its first two years on the market, and we’re excited to expand the solution to Spartan mowers.”

By increasing oil maintenance intervals to 500 hours, and with its easy fill cap and integrated oil filter, the Oil Guard system not only improves productivity but ensures oil changes are cleaner, faster and easier. The result is a 60 percent* oil maintenance cost-savings per unit and season.

“Adding the Vanguard Oil Guard innovation to Spartan Mowers aligns with our continued emphasis on improving ease of use and increasing productivity for our customers,” said Robert Foster, Owner, Intimidator, Inc.

The Oil Guard system will now be available on the Vanguard 37.0 Gross HP** EFI BIG BLOCK powered Spartan SRT and RT mower models. To learn more about Vanguard innovations, visit
