An ergonomic evaluation cleaner-cum-grader with original cycle mechanism and ICAR-CIAE developed dynapod was conducted. The study was conducted with 15 male subjects aged between 20-40 years, mean stature of 1640 ±40 mm and mean weight of 54 ±5 kg. The maximum aerobic capacities of the subjects were determined using sub-maximal exercise protocol. The mean working heart rate of the subjects in operation of machine with original cycle mechanism was 157 beats min-1 as against 125 beats min-1 with dynapod. The work pulse (ΔHR) of 57 beats min-1 and 31 beats min-1 was observed for pedaling with cycle mechanism and dynapod, respectively. The output capacity of machine increased by 41 kg h-1 with use of dynapod compared to pedaling with cycle mechanism. Using dynapod in operation of cleaner-cum-grader resulted in drudgery reduction by 51.6 % as compared to the original cycle mechanism.
