502 cab design

When the Valmet 502 was introduced in 1971 it had the world’s quietest cab.

When we look at the cab of the Valmet 502 today, we appreciate the total architecture of it even more than just the low noise level. The cab was tight. Thus, the requirements of both combating noise and controlled air conditioning were fulfilled. The cab floor was completely flat, and entrance was easy, thanks to large doorways. The driver's position was as natural as possible, the relations between seat and steering wheel were correct.

All the most important control levers were concentrated on the right side of the operator. The seat had a feature that was to be seen in other tractors only much later: it could be turned 30 degrees to the right and simultaneously tilted about eight degrees, and that gives a fairly comfortable ploughing position.

The cab had a functional form. The wedge-like shape meant good characteristics in the forest. The large glass areas, on the other hand, enables perfect visibility in all directions. Connections to the implements behind were managed by lifting the passenger seat at the back into an upward position and opening one half of the rear window. Outside, behind the cab, there was a position control lever that facilitated hitching implements.

In looks, this novelty differed radically from any other tractor. The bonnet began to show the wedge-like form, typical of Valmet, and the access to servicing points got easier.
