Experimental stabilization of tractor and tractor-trailer like vehicles
Proceedings of the IEEE Internatinal Symposium on Intelligent Control, 2003An 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, 2010We 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 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, 1996ABSTRACT 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.

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.

Using Tractor Test Data for Selecting Farm Tractors [PDF]
, 2016 The Nebraska Tractor Test Laboratory (NTTL) at the University of Nebraska is the official U.S. tractor testing station for the Organization for Economic Cooperation and Development. This laboratory has the responsibility for testing all models of tractors sold in the state of Nebraska, and it publishes the results of all tests it conducts.
