This robust and versatile machine, often seen alongside its sibling, the 1394 model, provided farmers with a dependable workhorse for a wide range of tasks. Powered by a Perkins 6.354 four-cylinder diesel engine, the 1390 boasts impressive power and torque, making it capable of handling heavy-duty plowing, harrowing, and other demanding agricultural operations. Its distinctive styling, characterized by a rounded bonnet and a prominent radiator grille, has become iconic in the world of vintage tractors. Although its production ceased in the late 1980s, the 1390 remains a popular choice for collectors and enthusiasts, drawn to its reliability, simplicity, and nostalgic charm. The 1390's versatility extends beyond its powerful engine. It features a well-designed hydraulic system, allowing for the efficient operation of a wide array of attachments, including cultivators, balers, and mowers.
