According findings, both BPDS HR went up as engine rpm up. The most common sites pain neck, lower back, legs, feet, wrists. minimum mean was 18.90 at depth 10 cm speed 1000 rpm. While maximum 28.67 30 2000 speed. variation due significant 5 per cent level. lowest value obtained 1000rpm whereas highest values 88 101 beats/min respectively. Tillage with a plough associated “low” workload steady state, seen by observed all participants, exception speed, where effort moderate. ΔHR
