Background and aims:Agricultural mechanization is a method for transiting from traditional agriculture towards industrial and sustainable one that follows the body and psychic discomfort reduction by method, devices and work condition reformation. The aim of the present study was to assess risk factors related to musculoskeletal disorders (MSDs) and mechanization intervention to reduce these disorders.

Methods:This interventional study (descriptive-analytical) was conducted on 80 workers in a edible mushroom producing unit. The Nordic MSDs Questionnaire and mixed-method were used to collect data and the postural workloads evaluation before and after the interventions, respectively. χ2 and logistic regression were performed to analyze the data.

Results and Conclusion: Regression analysis showed significant relationship between, shoulder, fingerhands and wrist and mechanization, between the pain of back and knee and The number of working hours per week and body math index, between the pain of back, knee, shoulder and arm and age. Due to significant reduction in MSDs after mechanization intervention, use of standard equipments in the semi machanization levels of mushroom harvesting and packaging is suggested.
