Yanmar Ct118 Review

The CT118 is not designed for commercial row-crop farming, but it excels in niche applications:

The CT118 is almost always paired with the YL115 front-end loader (though some units sold under other brands like Cub Cadet used slightly different loader codes).

YL115 Loader Specifications:

Hydraulic flow: The tractor’s hydraulic pump provides approximately 6.4 GPM (total) – enough for loader operation but slow for high-demand attachments like a log splitter running off rear remotes (if equipped).

Rear Remotes: Not standard. Typically, one or two rear hydraulic remotes were optional field-installed kits.

Pros:

Cons:

Before we look at the horsepower figures, it is vital to understand the pedigree. Yanmar is not a newcomer to the tractor game. Founded in Osaka, Japan, in 1912, they are the world’s largest manufacturer of compact diesel engines. For decades, Yanmar engines have powered tractors from John Deere and other major brands.

The CT118 represents Yanmar’s dedicated push into the North American sub-compact market under their own brand name. It is designed to take on the Kubota BX series and the John Deere 1 Series, but with a distinct Japanese engineering philosophy of “small but sturdy.”

The Yanmar CT118 is a specialized, rubber-tracked compact tractor designed for high traction and low ground pressure. Originally engineered for the Japanese domestic market, it has become a popular grey-market import worldwide for small-scale farmers, landscapers, and vineyard operators who need to navigate demanding terrain without compacting the soil.

Below is an in-depth breakdown of the Yanmar CT118, covering its core specifications, advantages, and ideal applications. Core Specifications

The Yanmar CT118 brings a unique blend of tracked mobility and small-footprint maneuverability. Engine: Yanmar 3-cylinder liquid-cooled diesel. Power Output: 18 horsepower. Drive System: Full rubber tracks (Crawler). Aspiration: Naturally aspirated. Rear Hitch: Category 1 three-point linkage.

PTO (Power Take-Off): Standard rear PTO for running active implements like tillers and flail mowers. Key Advantages of the CT118

The standout feature of the CT118 is its tracked undercarriage, which drastically changes its performance profile compared to a standard wheeled compact tractor. 1. Exceptional Flotation and Low Ground Pressure yanmar ct118

Wheeled tractors concentrate their entire weight on four small contact patches. The CT118 distributes its weight across the entire length of its rubber tracks. This ultra-low ground pressure prevents soil compaction, which is critical for maintaining healthy soil structure in gardens, greenhouse beds, and delicate agricultural operations. 2. Superior Traction in Challenging Conditions

The continuous contact of the tracks allows the CT118 to crawl through deep mud, loose sand, and wet clay where wheeled tractors would quickly spin out and get stuck. This makes it an ideal machine for early spring field prep or working in low-lying, boggy areas. 3. Increased Stability on Slopes

The wide stance and low center of gravity inherent to crawler tractors make them much safer on hillsides and uneven embankments. The tracks grip the slope firmly, reducing the risk of sliding sideways or rolling over. 4. High Pushing and Pulling Power

Traction translates directly into pulling power. Despite having a modest 18-horsepower engine, the CT118 can put a high percentage of that power directly to the ground. It can pull heavier ground-engaging implements (like small subsoilers or discs) than a wheeled tractor of equivalent horsepower. Ideal Use Cases

While it cannot match the top travel speeds of a wheeled machine, the CT118 excels in specialized niches:

Wetland and Rice Paddy Farming: Perfect for working in saturated soils where traditional tires create deep, destructive ruts.

Orchards and Vineyards: The narrow profile allows it to fit between tight rows, and the tracks provide the grip needed to pull sprayers up muddy terraced hills.

Commercial Landscaping: Ideal for grading and site prep on soft, finished lawns where minimizing turf damage is a priority.

Small-Acreage Market Gardening: Used primarily with a rotary tiller (rotovator) to prep perfectly loose seedbeds without packing down the subsoil. What to Know Before Buying

Because the CT118 is generally found as a used Japanese import in western markets, buyers should keep a few logistical points in mind:

Track Condition is Critical: Check the rubber tracks closely for dry rotting, deep cuts, or missing lugs. Replacing tracks on imported Japanese crawlers can sometimes be costly or require ordering from specialized overseas suppliers.

Check the PTO Rotation: Japanese tractors sometimes feature multi-speed PTOs or counter-clockwise rotations on specific models. Ensure the PTO on your specific unit matches standard clockwise implements if you plan to use standard off-the-shelf attachments.

Parts Availability: While Yanmar diesel engine parts are widely available globally, specific chassis, body, and track-undercarriage parts for the CT118 may require sourcing through specialized grey-market tractor parts dealers.
