This presence the machine affect of soil structure on condition of compaction. In this manner, this work had the principal aims the valuation to effect the number for steps the Harvester in the trash compaction for forest ...

The present work was undertaken on the experimental campus of the Universidade Federal de Lavras, on a soil classified a dystrophic dusky red Latosol, clayey texture, with a view to evaluating the influence: a) of the time ...

This research work was undertaken at the Universidade Federal de Lavras, on a Dark Red Latosol, dystrophic and of clayey texture with the purpose of evaluating the effect of 2 sowing systems and 9 cultivation systems upon ...

The objective of this paper is the valuation of two prototypes of precision seeding mechanisms specifically developed to peanut crop. Both mechanisms are vertical rotors, with 16 cells to seeds each one. The difference is ...

This research evaluated the effect soil compaction in function soil’s density and depth of furrow left through tractor of wheeled with different level of footing with view the compare the aftermath on field with the value ...

This work evaluated the development of a compacted layer in different types of soil management practices. It was developed on Oxissoils, at the Experimental Field of the School of Agricultural Engineering/UNICAMP. The ...

The objective of this work was to study the agricultural tractor tire deformation. The tire deformation is an important factor that define the ride vibration, the lateral stability and traction capacity of a tractor. In ...

Because primary soil tillage is considered the highest energy and time demanding operation, plowing is one of the refences for selection of tractor power. In a Terra Roxa Estruturada soil at the Fazenda Experimental ...

The water content effect applied pressure were analyzed on “Terra Roxa Estruturada”, on classes of aggregates of 0 to 2.5 mm; 2.5 to 5.1 mm; 5.1 to 9.4 mm and 9.4 to 19.3 mm. There has been used water content rates of ...

A precision pneumatic metering and transport system for seeds was developed. This system can be adapted for continuous flow. It includes a valve for conversion of pressure to vacuum and a pneumatic metering system coupled ...
