Fives and ones

In 1966 the UR I series was extended with the largest model 5511 with the power of 52 hp (38 kW). The tractor boasted a modern and impressive look. In addition to its design it represented other innovations as well: a new engine, a better torque, a rigid U profile front axle, hydraulic steering booster and a new dashboard. A very important optional accessory was the cab, which protected the driver if the tractor toppled over.
