Fire, Tractors, and Health in the Amazon: A Cost-Benefit Analysis of Fire Policy
Land Economics, 2019Pollution from agricultural fires is a global health issue that is particularly challenging where smallholders depend on burnings for subsistence. In Acre state, Western Amazon, a partial ban on fire, enforced with fines, is coupled with subsidized ...

IEEE Transportation Electrification Conference and Expo, 2019
This paper presents a feasibility study for the electrification of a farming tractor. In such an application the working cycle is not that trivial and then the system design is not straightforward: power has to be supplied at both road and power take off

Operator protection in rollover events of articulated narrow track tractors
Biosystems Engineering, 2019Articulated steering arrangements, wheeled or tracked, are commonly used on agricultural tractors and earth moving machines. In Continental Europe and Italy in particular, this configuration is typical of narrow track tractors.

Analysis of fatal accidents with tractors in the Centre of Portugal: Ten years analysis.
Forensic Science International, 2018Tractors have been described as one of the deadliest farming implements concerning agricultural activity. In Portugal, the scientific investigations about this problem are practically non-existent, with only statistical studies performed by entities ...

Coordinated path tracking of two vision-guided tractors for heavy-duty robotic vehicles
Robotics and Computer-Integrated Manufacturing, 2018Heavy-duty robotic vehicles are increasingly required to transport and position large-quantity and large-scale objects in the manufacturing process. The load-carrying capacity of vehicles can be enhanced by configuring multiple automated guided tractors ...

Polar Record, 1936
One of the earliest of the Hudson's Bay Company's experiments in tractor transport work was at Rupert's House in 1924. The machine used was a Citroen modelled after the tractor-type machines which had given such excellent service in the Sahara. It was not successful, however, so details covering its operation would be of little interest.
