Oil Guard™ System


Ferris Commercial Mowers with the new Vanguard Oil Guard™ System raise the bar on how productive a landscape contractor can be on any given day.

A first-of-its-kind solution for the commercial turf market, Ferris mowers with the Oil Guard™ System offer major productivity gains by allowing landscape contractors to operate their mower for 500 hours between oil changes. Increasing the oil change interval by 5x means less time spent changing the oil and more time cutting.

  1. Easy fill cap and integrated oil filter make oil changes easier, cleaner and faster.
  2. High-capacity external oil reservoir keeps oil and engine cooler.
  3. Unique, dry sump system ensures off-angle lubrication and minimizes thermal breakdown of oil.


  • Extended oil change intervals from 100 hours to 500 hours.
  • Larger volume of oil, means half the usual contamination in the oil.
  • Large oil filter with fine filtration ability.
  • Consistent engine lubrication during off-angle operation (up to 45 degrees).
  • Cleaner, faster, easier oil changes without need of tools.
  • Decreased oil change labour, replacement filter and oil costs.
  • Reduces downtime, increases productivity.
  • 3-Year commercial engine warranty†.
  • Exclusively available on Vanguard™ EFI engines on Ferris mowers.

* Cost savings based on standard oil maintenance with 100 hour interval versus Oil Guard™ System 500 hour service interval.
