In this paper, we present a multi-modal dataset for obstacle detection in agriculture. The dataset comprises approximately 2 h of raw sensor data from a tractor-mounted sensor system in a grass mowing scenario in Denmark, October 2016. Sensing modalities include stereo camera, thermal camera, web camera, 360 ∘ camera, LiDAR and radar, while precise localization is available from fused IMU and G...

A small, truck-type slewing crane with a grab was centrally mounted at the front of an 8-ton box-type tipping trailer. The crane and grab were operated by the hydraulic system of the tractor. Attempts to modify the control valves of the crane were not successful and it was concluded that the standard controls supplied for truck-type cranes were not suitable for this purpose. A standard double-a...

Leishmaniasis has been of concern to the U.S. military and has re-emerged in importance because of recent deployments to the Middle East. We conducted a retrospective probabilistic risk assessment for military personnel potentially exposed to insecticides during the "Leishmaniasis Control Plan" (LCP) undertaken in 2003 at Tallil Air Base, Iraq. We estimated acute and subchronic risks from resme...

This study investigates the influence of blade lifting angles, tractor forward speed, and power take off (PTO) speed on degree mulching. Four blades with different two PTO speeds, three speeds were assessed using parametric test at Universiti Putra Malaysia oil palm plantation. The result shows that best-fit regression equation was a quadratic high coefficient determination. It indicates any ch...

A spray drift model was developed to deliver real time information to the pesticide applicator. The sprayer is equipped with sensors to deliver real time measurement of operational parameters as spray pressure, boom height, horizontal boom movements and geolocalization. The spray droplet size spectrum as a function of pressure was characterized using PDI measurements. Wind speed and direction w...

In a mature Vitis labrusca L. ‘‘Niagara’’ vineyard, we compared an airblast sprayer and an air-assisted rotary atomizer (AARA) low-volume sprayer for coverage of grape clusters and control of grape berry moth, Paralobesia viteana. In addition, the effect of spray volume on control of fungal diseases was evaluated using the fungicides ziram and azoxystrobin applied with an airblast sprayer. For ...

Previous studies have reported that tractors are responsible for high proportions of fatal and nonfatal agricultural injuries. However, many common and preventable risk factors, conditions, and associated costs related to tractor-related injuries have not been investigated. This case-based study used workers' compensation data to investigate tractor-related injuries. The objectives of this stud...
