Résumé:
Seeking the mechanization of the intermediary transport in Brazil it was studied a animal draw ratched, developed by sugarcane suppliers of Pernambuco, and improved by the Agricultu ral Mechanization Section of the Coordenadoria Regional Norte of PLANALSUCAR/IAA. The ratched was taken to Campos, State of Rio de Janeiro, were the field trials were held, seeking to evaluate its performance under typic conditions of the declivous areas of the sugarcane region of Campos.
For traction of the ratched was used 2 and 3 oxen yoked in tandem. The animais were caracterized by the lifetime, wei ght, hight in the withers and toraxical perimeter, and the ana morphosic index of each one. To the trials with two yokes, it was discharged the middle yoke. The ratched operational cicie presents the following sequence of operations: a) loading in fi eld; b) loading transportation; c) unloading in the "point" and d) empty transportation.
It was used the flow of transportation (FT) as a parame ter for the evaluation of the capacity of the sistem, anã it ga thers the factors load, distance and time.
To evaluate the performance of the ratched with animal traction it was of located at the Morro Grande Farm, of the Ou teiro Mill's property. It was used the same and two operators for boath trials. For each set it was recorded data from 10 cf cies (10 replications) including: Time (S), wasted in each fase of the cicie; distances (m) covered loated and emply in each ci_ cie, and load (kg) transported.
To analyse the data in was used the Wilcoxon test of the nomparametric field besides the correlation analysis, of the pa rametric field.
From the achieved results, it was conckuded that the be_ haviour of the studied equipament is affected by the yokement conditions of the animais and by the way of management.
