Zetor 4911-6945

In 1978, the small Zetor tractors transitioned from the 7 series to the 9 series. The engines had a larger displacement than before, and the combustion chambers were redesigned. The front axles of the four-wheel-drive models were equipped with planetary gear sets. The front lights were now protected. The spacious cabin, again manufactured in Finland, featured tinted glass, and the lift control levers were finally positioned higher than before. Battery removal was also partially made easier. The electrical system was the last among tractor manufacturers to switch to an alternator. The main gear lever was still in its old place on the dashboard. The floor still contained a collection of control devices, and there was still much room for improvement in other parts of the cabin.

By the turn of the 1980s, four-wheel-drive models accounted for over half of Zetor's sales.
