The sugar cane crop is one of the main products in Brazil and according to several authors
can generate, besides the industrialized stalks, an amount of crop residues from the order of 15 to 30
% in weight of the aerial part of the plants, depending on the field conditions. The sugar cane area in
Brazil is around 5.5x106 hectares, with an amount of 400.106 tons of stalks, with stalks yield of 72
tons.ha-1. This study took place in a sugar cane plot (Latitude 2246S, Longitude 4723W and 600m
of altitude) with 3% of slope, located in So Paulo State. The sugar cane variety was SP 80-1816, in
its forth cut, 11 months old and with a planted row spacing of 1.40 m. By other side, several sugar
mills are bringing the crop residue to their patio to produce energy with the bagasse. One choice is to
bring the crop residue at the same moment with the stalks, avoiding the next operation of baling it.
The objective of this study was to analyze some operational parameters of two different sugar cane
harvesters under the same field conditions, which was divided in four treatments: T1 = CAMECO CHT2500B operating normally; T2 = CAMECO CHT2500B operating without the cleaning system; T3
= CASE 7700 operating normally; T4 = CASE 7700 operating without the cleaning system. The
results obtained were:
