Since this model is a rebadged version of the LS Tractor MT118 (Yanmar manufactures the chassis, and LS provides the platform in certain markets), parts and service procedures are often cross-compatible.


3. Key features (typical for Yanmar compact drivetrain units)

  • Compact footprint for space-constrained installations
  • High torque capacity relative to size due to robust gearing and materials
  • Corrosion-resistant finishes and marine-grade seals when intended for marine use
  • Multiple mounting/shaft options to fit diverse engine couplings
  • Serviceable design: access points for lubrication, inspection, and replacement of wear parts

The Heart: The 3TNV76 Engine

The CT118 is powered by a Yanmar 3TNV76 diesel engine. This is a liquid-cooled, 3-cylinder indirect injection engine.

  • Horsepower: 24.8 HP (Gross) / 18.5 HP (PTO)
  • Torque: Unlike air-cooled singles or twins, this triple provides smooth, lugging power.

Why this matters: Indirect injection engines are slower to rev but incredibly fuel-efficient and easier to start in cold weather than direct injection models. You will burn significantly less fuel per hour than a comparable gas lawn tractor.

5. Installation considerations

  • Alignment: precision shaft alignment to avoid premature bearing and seal wear
  • Mounting: rigid support to limit vibrations; use of anti-vibration mounts where appropriate
  • Coupling: correct flexible coupling selection to accommodate misalignment and torsional loads
  • Cooling/ventilation: ensure adequate airflow or oil cooling if operating near rated loads for long durations

Key Features:

  1. Powerful Yanmar Engine:

    • The CT118 is equipped with a robust 18 horsepower Yanmar diesel engine, providing ample power for a variety of tasks, from mowing and landscaping to light plowing and hauling.
    • Its fuel-efficient design ensures long working hours with minimal fuel consumption.
  2. Smooth Operation:

    • Hydrostatic Steering: Offers effortless and precise steering, making maneuverability a breeze, even in tight spaces.
    • Easy-to-use Controls: Intuitive and accessible controls ensure that operators can focus on the task at hand without unnecessary complexity.
  3. Versatility at Its Best:

    • 3-Point Hitch: Compatible with a range of implements, allowing for easy attachment and detachment for various tasks such as digging, lifting, and mowing.
    • PTO (Power Take-Off): Enables the use of PTO-driven equipment, enhancing the tractor's capability to handle more demanding tasks.
  4. Comfort and Safety:

    • Operator-centric Design: A focus on operator comfort with a spacious platform, low vibration, and an ergonomic design reduces fatigue during extended use.
    • Safety Features: Includes features such as a Rollover Protective Structure (ROPS) to ensure operator safety.
  5. Durability and Maintenance:

    • Built with high-quality materials and designed for easy maintenance, the Yanmar CT118 ensures long-term reliability and performance.
    • Easy access to service points simplifies routine maintenance tasks.

PTO Operation:

  • Engage only at idle (1000–1200 rpm).
  • Use PTO lever (left of seat) to engage mid or rear PTO.
  • Increase engine throttle to 540 PTO rpm (usually ~2600 engine rpm – check decal on dash).
