Method for calculating walking tractor performance considering operator's energy consumption

Annotation The paper proposes a method for calculating the performance of a walking tractor considering the operator's energy consumption in the dynamics of the tractor movement. The study presents the results of a man's energy consumption determined during physical load. The work has established that the performance of the walking tractor directly depends on the value of operator's physical action on the cultivator movement. The increase of the operator's physical effort decreases the performance of the walking tractor, since the operator has to increase the rest time for rejuvenation. The authors have suggested a method for walking tractor performance calculation considering operator's physical capabilities and his involvement into the tractor operation.
