By ergonomic design/modification we can increase output of the operator with great safety and comfort. Exports are invited to highlight the way to strengthen the ergonomic design aspects.
The best way to use the principles of anthropometrics is to do the work study, time study and method study of the equipment in question. Further the motion study can be used as a superlative tool for accurate use of the anthropometrics. Design modification may not necessarily mean changing/replacing the existing tool with a new/redesigned tool, however, modified version of the same can be adopted. Now into anthropometrics, the principles of design is to be adopted however, practicality, and user interface specific customizability in design consideration may be adopted. This is because of the presence of high diversification in population within miles.
Measure physiological response from the farmer during they work with new design of equipment that related to the anthropometry data. This can be , oxygen consumption, heart rate, cardiovascular load, static or dynamic muscle load , %MVC, MPF together with subjective response of the workers.
First, make sure your anthropometric data is representative of the population. Second, develop a cost-benefit case, using the methods outlined above and historical data on injuries etc,. to convince regulatory authorities to mandate the use of good ergonomic practices based on your data.
It might help to look at mine and our lectures in the course Elementary Ergonomics; free to look at https://ocw.tudelft.nl/course-lectures/ergo-l1-intro-to-1d-ergo/?course_id=13118
and for anthropometric data please have a look at my interactive tool www.dined.nl
Thanks for interesting answer by Joydeep, Pongjan, George and John.
Anthropometrics are based upon defined population surveys. Determine the user population and base the agricultural equipment design requirements on that set of statistics. To enhance human performance and validate data, perform user evaluations and develop questionnaires to provide user feedback and lessons learned. This will reveal whether the ergonomic design requires refinement.

Anthropometrics data are very important but, when we design artifacts to support one activity is important take in count some informations about that activity and analise the worker in action in the field. This can be used to inform the project, is something like recover the experience of the users to put that experience as part of the solution.
The ergonomic aspects during application in agricultural machinery are of great importance as the operator has to operate the machine in field. The physiological as well as psychological fatigue affects performance of the operator. Its purpose is to increase the safety, comfort and performance of a product or an environment, such as an office. Ergonomics uses anthropometrical data to determine the optimum size, shape and form of a product, and make it easier for people to use. Ergonomics, as Man-Machine-Environment System, deals with the machine, its operator and working environment as a complete system affecting the intended work performance. It is sometimes known as human factors engineering or human engineering. It deals with the physical work environment, tools and technology design, workstation design. Anthropometric and strength data of agricultural workers is very essential for the safe, user-friendliness and efficient design of farm equipment. The HG1 and HG2 reduce frequency-weighted vibration acceleration (rms) from the existing handle grip. Handle grip made of foam rubber was most preferred by all the subjects over the existing handle grip.
If one consider anthropometic data in the ergonomic design keeping safety & comfort of the operator
then definately performance is increased. There are many research output on this aspects. Now a days tractor design is also one example.
The availability of practical experience in the maintenance e and repair of agricultural equipment and knowledge of the type of equipment or machine design are to be modified .without changing the technical specification of the machine
