Self made cabs. In the 1960s, many local manufacturers in Western countries produced metal cab- ins that could be screwed onto tractors as a kind of self- build package. These cabins often had an adjustable heating system and for an extra cost air conditioning and radio as well. In that time the cabins were mounted on the tractor by a dealer or the farmer. The large popular tractor brands often had a cabin manufacturer as the main supplier for assembly on the farm, such as this Hini- ker cabin on this Oliver 2255 from 1973.
Wider view. German manufacturer Deutz Fahr set a new standard in the tractor world in 1995 with the launch of the Agrotron series, with a striking cabin in the shape of a fish bowl. This gave the driver much better visibility. Better welding techniques and stronger steel constructions made it possible to make the vertical cab posts thinner without making concessions to tilt safety. With a larger glass surface, the effect of the sun heating the cabin also increased enor- mously, making air-conditioning essential.
Better suspension. Nowadays cabs have a form of sus- pension that is standard so that they can cope with the increased maximum driving speeds of tractors. Manufacturers use spring sys- tems that employ hydraulics, air, torsion bars or steel springs, com- bined with shock absorbers. The French manufacturer Renault was a trendsetter with the introduction of the TZ series in 1987, which equipped with a cab with suspension system copied from the Renault truck division.
1976 and from 1983 all tractors in use in the EU must be equipped with a safety cabin or frame. From 1976 almost every tractor manufacturer, inspired by legislation on working conditions, had set itself the goal of being able to supply a cabin that produced ear-level noise below 86 dBA (adjusted decibels). At the time, they

thought that this was sufficiently low-noise to safely spend an 8-hour working day without hearing protection; 86 dB(A) is equivalent to the noise of a hard working food blender in the kitchen. In modern tractor cabs, the noise level has dropped to around 73 d(B)A: quieter than some cars these days.
The Future? How will the cabin develop over the next dec- ade? Will it be bigger and more luxurious? Will be a moving of- fice with a more pleasant interi- or? On the next pages you can read about CNH Steyr’s opinions.
