The John Deere 2155, 2355N, 2355, 2555, 2755, 2855N, 2955, and 3155 tractors represent a significant era in John Deere's agricultural machinery history. These models were introduced in the late 1970s and early 1980s, becoming popular choices for farmers and ranchers due to their robust construction, powerful engines, and advanced features for their time. These tractors were known for their versatility, handling a wide range of tasks from plowing and planting to harvesting and hauling. They were available in various configurations, with different engine options, transmissions, and hydraulic systems to suit diverse agricultural needs. The "N" designation signified narrow-front models, offering greater maneuverability in tight spaces. The John Deere 2155, 2355N, 2355, 2555, 2755, 2855N, 2955, and 3155 tractors were powered by a range of six-cylinder diesel engines, offering horsepower ratings from 110 to 155. These engines were known for their reliability and fuel efficiency. The tractors featured a variety of transmissions, including single-stage and dual-stage clutches, high-low shift units, and optional creeper transmissions, providing operators with precise control over speed and power. The hydraulic systems on these tractors were also impressive for their time, offering power to operate implements, lift heavy loads, and provide auxiliary hydraulic functions. These models incorporated features like selective control valves, ISO breakaway couplers, and remote cylinder capabilities, enhancing the tractors' versatility and efficiency.
