the aims of this study were about determining of amount of accuracy in tractor-moldboard plow system for tillage operation on paddies and also survey on efficacy of decision support software application on amount of energy use. for this purpose, decision support software was developed by visual basic 6.0. for survey in amount of efficacy of applying the decision support system on paddies tillag...

The paper aims at the complex situation of the tractor field operation and adopts the gear shift rule of two parameters to control the six gear shift of the tractor. Using the artificial neural network chip the model number of which is ZISC036 and the computer on slice the model number of which is PIC17C42 establishes the controller of the radial basis function artificial neural network-RBFANN....

excessive cutting depth during leveling of agricultural land increases power needed by the tractor drawbar and will result in undesirable slippage and excessive strain on the tractor engine.  the result of sustained excess will be the break-down of the tractor. an auxiliary blade depth controller to prevent overloading during leveling was designed, fabricated and evaluated in this study. the sy...

Selecting the appropriate tyre configuration and settings for heavy farm vehicles is important to ensure that soil compaction power loss in rolling resistance are minimised traction optimised. This study investigated effect of front-wheel assist (FWA, ≈75 kN) four-wheel drive (4 WD, ≈100 tractors fitted with different configurations (single, dual), sizes inflation pressures on strength (a proxy...
