“…These data observed for harvester efficiency in treatment A ( Figure 5 and Table 1), were close to the work conducted by Segato and Daher (2011), who evaluated the efficiency of sugarcane harvesters without using technologies such as GPS and RTK, and found losses of 10% of the final raw material harvested, a fact considered by the authors Brunini e Petrucci, v.12, n.43, p.79-88, Dourados, 2019 as a concern for the sector because the producers end up having a deficit in the order of millions of dollars per year. This can be avoided by using technologies linked to the GPS and RTK (autopilot) tools instrumented in agricultural machinery and equipment for the production of sugarcane.…”

Brazil is world leader in the production of sugarcane, crop that is grown in several regions of the country and responsible for the generation of sugar and ethanol. However, maintaining high productivity in the field requires that productive areas are increasingly equipped with innovative solutions that provide increased efficiency in crop management. The main focus of agricultural systematization is using georeferencing and geoprocessing to make more efficient the trafficability of agricultural machines and increase the productive area, reducing the costs with field operations and the risks of failures in cultures caused by trampling. The objective of this study was to evaluate the operational efficiency of autopilot on trafficability and reduction of trampling into a sugarcane harvesters cultivated area. Efficiency tests were carried out in an area cultivated with sugarcane divided between two treatments, using the autopilot with satellite navigation coupled in the harvester and in the other area, the harvester maintained the common working method (without use of automatic pilot). The data generated by the equipment were collected and the parameters of fuel consumption, operational time, production harvested and harvest losses were evaluated, compared and interpreted through multivariate statistical analysis. The results of this study indicated that the treatment using harvester with autopilot, there was significant field harvest efficiency (7.6 Mg h-1) and a reduction in fuel consumption (on average 10%) when compared to the harvester without autopilot.

Sugarcane (Saccharum spp.) stands out as one of the main crops of Brazilian agribusiness. Currently, the crop harvesting process is predominantly mechanized. The objective was to evaluate the losses and impurities in the mechanized harvest of sugarcane as a function of working speed and rotation of the primary extractor. The experiment was conducted in a sugarcane harvested without previous burning, using the variety CTC 15 in its first cutting stage, classified as upright. The row spacing was 1.5 m and the average crop yield was 92.5 Mg ha -1 . A single-row harvester was used, operating at three working speeds, being V1 (3.0 km h -1 ), V2 (5.0 km h -1 ) and V3 (7.0 km h -1 ). Two rotations of the primary extractor were used, R1 (700 rpm) and R2 (1000 rpm). In the experiment, the loss of raw material and the vegetable impurities were evaluated shortly after the harvester went through the experimental area. With the highest rotation of the primary extractor, there were average levels of vegetable impurities (4 to 6%), and with the lowest rotation, there were high levels (> 7%). Levels for plant losses were low (< 2.5%) for all evaluated treatments.Additional keywords: evaluation; mechanization; performance; quality. ResumoA cana-de-açúcar (Saccharum spp.) destaca-se como uma das principais culturas do agronegócio brasileiro. Atualmente, o processo de colheita da cultura é, predominantemente, realizado de forma mecanizada. Objetivouse avaliar as perdas e as impurezas vegetais na colheita mecanizada de cana-de-açúcar em função da velocidade de trabalho e da rotação do extrator primário. O experimento foi conduzido em um canavial colhido sem queima prévia, sendo utilizada a variedade CTC 15, em seu primeiro estágio de corte e com porte classificado como ereto. O espaçamento entre fileiras foi de 1,5 m, e a produtividade média da cultura, de 92,5 Mg ha -1 . A colhedora utilizada foi de uma linha, operando em três velocidades de trabalho, sendo V1 (3,0 km h -1 ), V2 (5,0 km h -1 ) e V3 (7,0 km h -1 ). Foram utilizadas duas rotações do extrator primário, sendo a R1 de 700 rpm e a R2 de 1.000 rpm. No experimento, foram avaliadas a perda de matéria-prima e as impurezas vegetais logo após a passagem da colhedora na área experimental. As impurezas vegetais com a maior rotação do extrator primário apresentaram níveis médios (4 a 6%), e a menor rotação do extrator primário, níveis altos (> 7%). Os níveis para perdas vegetais foram baixos (< 2,5%) para todos os tratamentos avaliados.Palavras-chave adicionais: avaliação; desempenho; mecanização; qualidade.

“…Em experimentos realizados por Segato & Daher (2011), com duas velocidades de trabalho (8 e 6,5 a 7 km h -1 ), foi observado que os tratamentos não apresentaram diferenças significativas para a perda de tolete. Os mesmos autores chamam a atenção, relatando que esse tipo de perda pode ser totalmente influenciado pelo sincronismo entre operador da colhedora e operador do trator transbordo, e também pelo excesso de material adicionado dentro do cesto do transbordo acoplado ao trator, que ao se locomover pelo terreno pode perder toletes ao longo da linha.…”

“…Segundo Salvi (2006), a velocidade excessiva de deslocamento na colheita pode influenciar a perda tipo pedaço. Segato & Daher (2011) observaram que não houve diferença significativa para a perda tipo pedaço quando se avaliaram as velocidades de 7,0 e 8,0 km h -1 , corroborando os resultados do presente trabalho.…”
