Wheel efficiency is obtained as follows. ηW is the ratios of the power to advance against the output of the wheel axis.
ηW=cosδ(1-μ)
δ; Angle of rolling friction.
μ; Travel reduction, slip percentage of the wheel.
μ is one of the factor that shows the wheel faculty, and it is decided by the wheel motion which is followed by the load and the reaction force of soil to the wheel. There are one travel reduction to cause the stress in the soil which keeps the ballances against the loads.
In this paper, the motions of the farm wheel are analysed. α is the inclinated angle moving direction of one point on the wheel to the horizontal line, dF is the moving distance of that point, dF and dS are respectively perpendicular components of dF to that wheel surface.
