Analysis of the attache's technical yield formed by the tractor NEW HOLLAND TS6020 and the tier Cripple of 42 disks", for the work of gradation for the cultivation of the rice (Oryza sativa) (Original)

Abstract

The present work was carried out in the Brigade #23, of the I FELL rice Fernando Echenique

belonging to the Municipality of Cauto River, Granma county , with the objective of evaluating

the attaché's technical yield formed by the tractor NEW HOLLAND TS6020 and the tier Cripple

(42 disks), through several indicators that evaluate the efficiency of the process. For this

evaluation some component elements of the picture timing were used for this work. Obtaining

that the work speed had a half value of 9,2 km•h-1 and the theoretical value of 10.4 km•h-1 for a

coefficient of use of the theoretical speed of 0,88, the coefficient of use of the constructive width

had a value of 0,97, the coefficient of use of the turn time had a value of 0,45, and the yield by

shift had a value of 12,22 ha•t-1. It was found a significant difference between the reached real

productivity and the theoretical one in 38%, as well as the theoretical use of the time of shift that

this tractor should reach for this work in 28%.
