Vanguard® 13,4 Gross kW

The Vanguard® 13,4 Gross kW* horizontal shaft engine combines compact power with superior endurance for equipment operating in commercial, industrial, and off-highway conditions. Featuring a space-efficient V-Twin design, it delivers 18 HP at 3600 RPM with reduced vibration and extended runtime—ideal for lawn tractors, utility vehicles, and power-intensive machinery. Built for longevity and consistent performance, this engine is designed to lower fuel costs and maintenance demands in harsh environments.

  • Power for heavy-duty tasks: Delivers reliable torque and output for load-bearing and continuous-use applications.
  • Smooth operator: V-Twin architecture enhances balance, minimizing vibration and improving user comfort.
  • Proven versatility: Compatible with a range of commercial mowers, generators, and specialty equipment.
  • Durable & efficient: Engineered for durability and fuel economy, supporting extended field operations with fewer refuels.
Features & Benefits
  • V-Twin OHV Technology
    Delivers superior power and balance, while overhead valve design enhances combustion efficiency, extends engine life, and improves fuel economy.
  • Smooth Easy Starting
    Mechanical compression release eases cranking force, and the Magnetron® ignition system ensures reliable, maintenance-free starts. Optional solenoid shift and recoil start configurations are available.
  • Maximum Durability
    Rugged engine block and cast iron sleeve construction protect internal components from wear, providing excellent oil control and high endurance.
  • Compact Design
    Designed to fit within tight envelopes without sacrificing power, supporting OEM flexibility in constrained installations.
  • Integrated Fuel Tank (Optional)
    Optional onboard tank maintains a compact overall footprint—ideal for space-limited engine bays or custom chassis integrations.
  • Extended Engine Life
    Spin-on oil filtration and dual ball bearings support full-pressure lubrication, enhancing protection and extending operational longevity.
  • Superior Balance
    Lightweight piston and ring set with a dynamically balanced crankshaft reduces noise and vibration under high load and heat.
  • OEM Selectable Speed Option
    ECU supports analog (0–5V) or CANbus input, allowing speed calibration to suit application-specific requirements.
