Engine Power Required When Using a Tractor with a Technology Module by M. V. Sidorov, A. V. Lavrov, V. A. Voronin, A. V. Sidorova

“…(Results and discussion) The authors showed that for a modular power unit with a 6K6 wheel arrangement, it is necessary to consider a number of additional factors having an impact on the accuracy of the calculation: firstly, the tractor’s traction and coupling properties depend on the number of driving axles; secondly, the wheel slippage along individual axes is not the same and occurs due to a constructively conditioned kinematic discrepancy in their drive; thirdly, the three-axle transmission efficiency can be determined only as a total indicator of three transmission branches, that is, to drive the tractor front and rear wheels and, separately, to drive the wheels of the technological module. …”
