The vibration conditions to which tractor operators are subjected are complex and varied with multi axis translation and rotational vibration inputs to different parts of the body. Working under such conditions may lead to human fatigue and other driving related hazards. The present research was carried out to study the operators under varying conditions of vibration while driving a tractor wit...

A Bessel beam without an axial gradient can exert a pulling force on an object [A. Novitsky, C. W. Qiu, and H. Wang, Phys. Rev. Lett. 107, 203601 (2011)]. However, it cannot be called a "tractor beam" per se, as long as the light pulling effect is ultrasensitive to the object's material and size, a perturbation of which will make the optical traction go away. In this Letter, we investigate and ...

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...

Autonomous guidance of agricultural vehicles is vital as mechanized farming production becomes more prevalent. It is crucial that tractor-trailers are guided with accuracy in both lateral and longitudinal directions, whilst being affected by large disturbance forces, or slips, owing to uncertain and undulating terrain. Successful research has been concentrated on trajectory control which can pr...

In agriculture, a typical task is to do a coverage operation for a field. Coverage path planning algorithms can be used to create the path for a vehicle. In case of an autonomous agricultural vehicle, the path is provided to the guidance or navigation system that steers the vehicle. In this paper, a four wheel steered tractor is used in autonomous sowing operation. The full size tractor is equi...

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....

There are competing economic goals when plowing a farm field. The rows must be level, to reduce erosion. The rows should also perfectly abut each other, so that no land is wasted on gaps and no fuel is wasted on overlapping areas. With todays GPS-guided tractors, it has become worthwhile to try to produce an optimal tractor path, knowing that a tractor can actually be programmed to follow it. T...

The directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. The dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank mode...

As the economic contexts of farming change, occupational supports for the maintenance of traditional rural masculinities diminish. When these past identities remain salient, identity discontinuity can occur and alternative mechanisms of support may be sought. Nostalgic remembrances may serve to reduce such discontinuity. The current inquiry explores antique tractor collecting as a means of rest...

automation of tractors due to their widespread use in different sectors e.g. agriculture, construction and industry have been seriously considered by researchers. in this study a tele-steering system for tractor was designed and constructed to controling and steering so the operator can control the tractor even far away from the stressful condition of tractor cab, . a cctv camera and an electri...
