## The Same 130S, 140S, 150S, and 165S: Powerful Italian Workhorses The Same 130S, 140S, 150S, and 165S tractors represent a range of versatile and robust agricultural machines produced by the Italian manufacturer Same (Società Accomandita Semplice Motori Endotermici). These models, typically manufactured between the 1970s and 1980s, are known for their durability, reliability, and powerful performance, making them suitable for a wide range of agricultural tasks. Each model within this series boasts a distinct engine size and horsepower output, catering to specific needs. The 130S, for example, is equipped with a 3-cylinder, 2.5-liter engine, delivering around 50 horsepower, making it suitable for lighter duties such as cultivating smaller fields or operating implements like a rotary tiller. The 140S, on the other hand, features a slightly larger 3-cylinder, 2.8-liter engine, boasting around 60 horsepower, ideal for handling medium-sized farms and more demanding tasks like plowing or pulling a baler. The 150S and 165S, equipped with larger 4-cylinder engines, offer even greater power, making them capable of tackling heavy-duty applications like pulling large plows or operating heavy-duty implements. These tractors are often equipped with a 4-wheel drive system for increased traction and stability in challenging terrain, as well as a three-point hitch system for attaching a wide variety of implements. The Same 130S, 140S, 150S, and 165S tractors are known for their simple yet effective design, making them reliable and easy to maintain. Their mechanical construction and robust components contribute to their longevity, making them a popular choice for farmers who value dependability and long-term performance.
