BETANCOURT-RODRIGUEZ, Yoel et al. Agro-technique Evaluation of a Cuban Tow in a VertisolPelic Typical Soil. Rev Cie Téc Agr [online]. 2017, vol.26, n.1, pp.23-31. ISSN 2071-0054.

In order to determine the fulfillment of agro-technical parameters of Cuban self-tipping trailer in intermediate transport of sugar cane inside the field, in heavy clay soil, with mound surface, an investigation was carried out in a Vertisol typical Pelic. The harvester CASE IH 8 000 and the Cuban self-tipping trailer coupled to the tractor Maxxum CASE 150 were the equipment that participated in the harvesting process. The results showed that Cuban Trailer does not fulfill the agro-technical requirements for the sugar cane transportation under the conditions mention before, for the following reasons: it surpasses the protection area of the plants, being located at 45 cm from the end of the mound base, with a standard deviation of ± 25cm. It means that 100% of the area is under machinery traffic, applying pressures higher than 300 kPa, similar to other equipment like Zil 130, RR 6 and RC 10 trailer which are not appropriate for the traffic in the sugar cane field. Also, the height of the mound diminishes at 65%, it compacts to the soil where the 90% of the cane roots are developed, because it increases significantly the apparent density and the penetration resistance until 20 cm from the superficial horizon, in soil humidity of 51% hbss. The modification of the self-tipping trailer was recommended for using it under these conditions
