CABIN HISTOR ▶▶▶Y
Tractor cabs: From rough and ready to comfortable workspace
For a long time, tractor drivers had to make do with a roll bar or simple cab to protect them if the tractor turned over. However, from the mid- 70s cabs appeared, providing more comfort and safety for drivers. A look back at the most important developments over the past 50 years. And in every Future Farming edition in 2020, a manufacturer will explain how the cabin will evolve over the next ten years.
Nicer, integrated design. In the late sixties, the ma- jor tractor manufacturers started designing and producing cabins themselves. This not only improved the appearance of the tractor, as with this Massey Farguson 575 and its Supercab (1976). The designers constructed the cabin as a free-standing part on the chassis, usually mounted on four rubber blocks (silent blocks), to keep out noise and vibrations. The controls were also much better integrated, which greatly improved the ergonomics for drivers.

n a modern tractor, a comfortable cabin is essential, although cabins have been available since the time tractors were first manufactured.
That a tractor cabin should do more than
Less noise. To get the noise level for drivers below an accept- able level of 80 dBa, John Deere introduced the so-called Sound Guard cabin, with a unique curved door integrated into the semi-cir- cular windscreen in 1972. The entire front of the cabin was deliber- ately bent to divert the sound of the engine around the cabin. John Deere held on to the SG cabin for more than 20 years. The John Deere 4955 series in the photo was only replaced in 1992 by the 60 series with a newly designed cab.
protect the driver against rain and wind only became the case in the early 70s. In 1959, Sweden was the first country in the world where a safety cab (roll bar) became mandatory for tractors produced in Sweden and in 1965 they also stopped importing trac- tors without such a facility. Sweden was there-

fore ahead of legislation worldwide. In the Unit- ed States a standard for rollover protection was developed by the American Society for Agricul- tural and Biological Engineers as early as 1967 and from 1976 this standard also came into law. In the European Union an approved safety cab- in was mandatory for all new tractors from
