The Experiment was carried out to determine
the level vibration transfer in three axes Horizontal X,
Lateral Y and Vertical Z direction to seat driver tractor,
Vector sum of vibration and Daily Vibration Exposure (8
hours) in seat driver tractor, and vibration in steering
wheel tractor, Heart Rate, Systolic and Diastolic blood
pressure and temperature were measure to all Drivers
before and after used Chisel plow in operation tillage.
Statistical analysis system was used, Split-Split Plot
Design under Randomized Complete Block Design, Three
factors were used in this experiment included Two types
of Soil Moist and Dry soil which represented main plot,
Three Velocity Tractor was second factor included 1.6,3.5
and 5.4 km/hr and Three Drivers Tr
