The Vanguard 400 horizontal shaft engine delivers powerful, high-displacement performance with the added benefits of advanced starting, extended maintenance intervals, and exceptional cold-weather reliability. Developed with direct customer input, this single-cylinder commercial engine is a high-torque, low-maintenance solution for demanding power applications. It’s a drop-fit replacement for legacy platforms—no modifications required—and includes a 3+1 year commercial-use warranty for peace of mind.

• Lower noise. Less vibration. Increased user comfort: Engine structure minimizes vibration and sound for smoother handling and less operator fatigue.
• Low TCO, reduced downtime: TransportGuard™, 600-hour air filter life, and extended oil service intervals significantly cut ownership costs.
• Ideal for simple replacement: Fast drop-fit installation for the most popular engine footprints—ready for immediate repower applications.

• Simplified 3-Step Starting
  Optimized for operator ease, the 3-step start system ensures faster, lighter recoil starts in any environment—proven at temperatures as low as -29°C.
• Eliminate Fuel/Oil Dilution
  The TransportGuard™ 3-in-1 control shuts off fuel and ignition at once, preventing oil contamination and downtime from transport-related failures.
• Optimized Fuel Management
  Improved fuel system maintains engine readiness, even with stale fuel, reducing risks associated with intermittent use or seasonal deployment.
• Advanced Engine Protection
  Integrated low oil sensor helps prevent engine damage by detecting critical levels, adding a layer of automated safeguard.
• Outperforms in All Terrains
  Optional 45° inclination package keeps the engine running smoothly on steep or irregular surfaces—ideal for rugged or mobile machinery.
• More Efficient Power Management
  Governed idle improves throttle stability at low speeds, offering precise control and fuel efficiency across varying load demands.
• Fewer Air Filter Changes
  Cyclonic air filtration system enables up to 600 hours between filter changes—doubling standard intervals for longer continuous use.
• Longer Oil Maintenance Intervals
  Doubled oil change cycles reduce labor and waste, lowering costs and improving sustainability with up to 50% less oil disposal required.
• Zero Overhang Muffler (Optional)
  Optional muffler design provides a clear mounting footprint, streamlining installation and repowering in tight engine compartments.
• Reduced Noise and Vibration
  Engine balancing and refined architecture decrease noise and vibration levels, enhancing user comfort and equipment stability.
