The purpose of this work was evaluating the energetic demand of a seeder-fertilizer machine as a function of the type and handling of vegetal covering culture and of the fertilizer deposition shank depth. A Valtra BM100 tractor was used implemented to pull a high precision seeder-fertilizer machine with four ranks of seeding, spaced 0.9 m for maize culture. Experiment was conducted with design in randomized blocks in factorial plots, in the Laboratory of Machines and Agricultural Mechanization experimental area (LAMMA) of UNESP-Jaboticabal, using two covering cultures (black-mucuna and crotalaria), three handlings of this covering, two mechanical (straw crusher and roller knife) and one chemical (pulverization of herbicide), performed 120 days after... |

ABSTRACT The controlled traffic of machines is a technique that performs the standardization of machine wheel gauges and width of implements, allowing them to move in predetermined places. The objective of this study was to evaluate the performance of an agricultural tractor, pulling seeder with configurations of furrows, in an area with controlled traffic of machines in various intensities. The study was developed in an agricultural area located in the municipality of Carazinho, RS. The experimental design was 3 × 3 randomized blocks, with traffic conditions (tractor traffic, tractor and harvester traffic, other tractor traffic, harvester and sprayer) and three configurations of furrows (double disk, double disk in the rows without traffic and rod in the... |
