Vanguard 200

The Vanguard 200 horizontal shaft engine provides 4.8 gross kW (6.5 HP) of high-performance output, purpose-built for compact machines and small-scale unmanned or utility platforms. Designed as a zero-reengineering drop-fit solution, it seamlessly replaces common engine types used in pressure washers, water pumps, compaction equipment, and similar demanding tools—while delivering best-in-class durability and service life.

  • Lower noise. Less vibration. Increased user comfort: Engineered to reduce sound and vibration levels for smoother operation and higher productivity.
  • Low TCO, reduced downtime: TransportGuardâ„¢, 600-hour air filter life, and double-length oil change intervals extend uptime and cut operational costs.
  • Ideal for simple replacement: Fully compatible with existing engine footprints—drop-fit installation simplifies integration.
Features & Benefits
  • Simplified 3-Step Starting
    Designed for ease of use in all climates, the optimized starting process shortens pull length and requires less effort—proven to operate reliably in temperatures down to -29°C.
  • Eliminate Fuel/Oil Dilution
    TransportGuard™ 3-in-1 control halts ignition and fuel simultaneously when stopped, preventing oil contamination—a leading cause of field failures in rental fleets.
  • Optimized Fuel Management
    Fuel system design resists degradation from stale fuel, improving engine readiness during seasonal storage or long-term deployments.
  • Advanced Engine Protection
    Built-in oil sensor protects against low-lubricant conditions, preserving internal components and avoiding premature wear.
  • Outperforms in All Terrains
    Optional high-inclination package supports full operation on slopes up to 45° in any direction—ideal for uneven terrain and mobile unmanned platforms.
  • More Efficient Power Management
    Governed idle enables better load response, efficient fuel use at idle, and precise RPM control under dynamic operating conditions.
  • Fewer Air Filter Changes
    Cyclonic filtration technology achieves 600-hour air filter intervals—doubling standard service cycles and improving uptime.
  • Longer Oil Maintenance Intervals
    Engine oil change intervals are twice the industry average, cutting maintenance frequency and oil use by up to 50%, significantly lowering total cost of ownership.
  • Zero Overhang Muffler (Optional)
    Clear flange muffler option allows for a cleaner engine profile, easing installation and improving compatibility with tight-mount platforms.
  • Reduced Noise and Vibration
    Enhanced internal balance and design improvements significantly reduce operational noise and vibration for a quieter, more comfortable user experience.
