Objective: The compatibility of human capabilities and limitations, in conjunction with operations and work environment, with the ways of designing machines is dealt within ergonomics. The placement of controls is a complex task for the designer who must take into account the anthropometric characteristics of his target population. The efficiency and comfort of the operator is improved with properly designed tractor workplace.

Design: Study was conducted in which the tractor operator workplace configurations of 5 different tractor models were measured using different measuring scales. The location of different tractor seat and control locations were calculated considering the biomechanical and anthropometric measurements. These values were given as design values for tractor operator’s workplace design. The ergonomic evaluation of workplaces of 5 different tractor models was carried out in laboratory as well as in the field.

Results: Studies on evaluation of the most efficient location of controls resulted in steering column angle of 65° with horizontal, foot pedals (clutch and brake) distance of 87.50 cm and the draft control lever distance of 28.68 cm from Seat Reference Point (SRP).

Conclusion: It was concluded that the values obtained from the different tractor workplace configurations under study should be nearer to design values so that the operator can operate it with efficiently and comfortably.
