Experimental stabilization of tractor and tractor-trailer like vehicles

Proceedings of the IEEE Internatinal Symposium on Intelligent Control, 2003
An experimental study of recently proposed algorithms for the stabilization of autonomous vehicles (articulated and non-articulated) is carried out. The idea is to investigate extent by which experimental behavior is in agreement with convergence, stability and robustness properties that are predicted by theory and simulation tests.

On the concept of “tractor beams”

Optics Letters, 2010
We demonstrate the existence of a class of optical beams where the nonconservative forces can be locally oriented in a direction opposite to the propagation wave vector. Objects placed in the vicinity of these locations will move toward the source of light.

Tractor stability indicator

Applied Ergonomics, 1985
Tractor overturns are a major cause of death in farm operations. The overturns are the result of interactions between the tractor operator, the tractor and the environment. Numerous variables involved in tractor overturn have been identified. Previous stability analyses have resulted in attempts to design devices to warn or prevent tractor rollover but

The System Tractor - Tire under the Influence of Tractor Development

Vehicle System Dynamics, 1996
ABSTRACT Tractor tires are noncircular and although the noncircularity is small, it has considerable influence on the stimulation of vibrations. In a research work at the TU - Berlin such tires are measured and a method was found to eliminate the noncircularities very easy and fast.

An Automatic Tractor Guidance

IFAC Proceedings Volumes, 2000
Abstract The need to carry out highly precise operations in order optimise input factors is in many cases hampered by the impossibility of following straight, equally-spaced paths during field operations. Ground operators or automatic systems can be used to improve guidance precision in the absence of marks in paddy fields.

INCREASING THE UTILITY OF THE TRACTOR

SAE Technical Paper Series, 1920
<div class="htmlview paragraph">The comparatively slow introduction of mechanical power for farm operations has been a surprise and a disappointment to many. It is easily understandable why the deficient machines failed to sell but not so clear why really efficient outfits failed to make greater headway.

Potential Performance Characteristics for Different Types of Tractors: Two-Wheel-Drive Tractor, Four-Wheel-Drive Tractors and Crawler Tractors

2018
The paper addresses a very important criterion for the evaluation of the tractive and economical performances of agricultural tractors, namely the potential performance characteristics, which represents the drawbar power curve depending on the drawbar pull.
