The farm inputs like seeds, fertilizers and produce are handled manually in most of the low-income and underdeveloped countries. Such practice of manual load carrying is one of the dominant contributors to back pain and associated physiological problems.In the present study, it was found that volume, quantum and distance determine the mode of load carrying. Bulky or voluminous commodities like harvested cereal crops and fodder are carried on the head. Heavy loads of paddy and vegetables filled in gunny bags, which limits the volume to bag size are carried on the back. Carrying the load on the head is by and large prevailing mode because it does not introduce eccentricity and postures remain balanced., In the present study, an attempt is made to develop a harness, which does not alter the head loading but prevents the loading of the spine. Three approaches considered were: Approach-I (harness H₁): load passing through shoulders only (one path only); Approach II (harness H₂): load passing through head and shoulder (through two paths only); Approach III (harness H₃): Load passing through head and shoulder (through two paths), but in this approach, load on the cervical spine was limited to 10 kg and rest of the load was transferred to shoulder with proper stability. The outcome of ergonomic studies showed that Approach-III is the most metaboliclly economical, compared to other developed approaches and could be adopted for Indian agricultural farm load carriage for various purposes.

在大多数低收入国家和不发达国家中，手工输入的种子，肥料和农产品等农业投入品都是手工处理的。人工负重的这种做法是导致背痛和相关生理问题的主要因素之一。在本研究中，发现体积，量子和距离决定了负重的方式。头顶上有大宗或大量商品，例如收获的谷类作物和饲料。装在麻袋里的稻谷和蔬菜很重，限制了袋子的体积，装在背上。由于不会引起偏心并且姿势保持平衡，因此在头上主要承担负载。，在本研究中，试图开发一种安全带，该安全带不会改变头部的负载，但可以防止头部的负载。脊柱。₁）：负载仅通过肩部（仅一条路径）；方法二（线束H ₂）：负载通过头和肩膀（仅通过两条路径）；方法III（线束H ₃）：通过头和肩膀的负荷（通过两条路径），但是在这种方法中，颈椎的负荷被限制为10千克，其余的负荷以适当的稳定性转移到了肩膀上。人体工程学研究的结果表明，与其他已开发的方法相比，方法III在代谢上最经济，可用于印度农业农场的各种目的运输。
