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...

This study investigates the potential hazard to vehicles of excessive roadside edge wedge (defined as a wide, deep edge treatment) and develops a safety design countermeasure. Using the Human Vehicle Environment (HVE) simulation tool, a typical driving scenario, road profile, and vehicle and driver behavior were selected to represent high risk situations. Wedge heights and slopes were modeled a...

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...
