Title: A Modular Cab for Farm Tractors
text: This paper discusses the design of the modular cab for the White Farm A4T tractor. The modular concept creates new problems in cab and tractor design and has a significant effect on tractor assembly line operations. The cab is particularly quiet and well sealed. Data regarding operator noise levels are presented with comparisons shown to similar products and recent legislative activities in the area of noise control. Operator environmental control is improved with the modular concept, and performance data and specifications are discussed. The end product is the result of a close cooperative effort by the tractor manufacturer and cab manufacturer brought forth by the need to provide the customer with a greatly improved cab.
