“…A possible explanation is the plot has an irregular shape, which made it difficult to access a bulk carrier tank to the machine for unloading of soybeans and several times the platform angle of attack was damaged; often causing accumulation of straw between the harvester mechanisms that is the "bushings". ARALDI et al (2013) studying the time efficiency in mechanical harvesting of rice in various conditions, using combined harvesters, reported an average time of discharge 10.8%, this value being near of found for this study in relation to irregular plot and higher than the other models of plots.…”

ABSTRACT:The knowledge of the operational quality of soybean harvester provides useful information to management in order to obtain the maximum performance of all available resources, with minimal expenses. The aimed of this study was to evaluate the quality of mechanized soybean harvesting operation in different formats of plots through statistical process control. Treatments were established from the formats of existing plots in the area (irregular, trapezoidal and rectangular). The activities carried out during the harvest were monitored (harvesting, unloading, handling, maneuvering and climate charts) and through these activities were made the calculation of capacity and harvesting operation efficiencies. In the determination of total losses were used 4 circular frames of 0.33 m² each, the grain losses were considered below and above these frames. The statistical analysis was by means of statistical process control opting for the use of the type CUSUM charts. The rectangular plot showed greater management efficiency and harvesting efficiency. The trapezoidal shape facilitated the maneuvers relative to others. The rectangular plot has better quality of operation in relation to others. The CUSUM control chart showed to be effective in preventing instability and maintenance of process quality.

“…According to Jokiniemi et al (2012), Rivera et al (2012), Shamshiri & Ismail (2013), Zaied et al (2014), and Oduma et al (2015), field efficiency has a direct influence on the operational field capacity of a machine and on mechanized operations themselves. As stated by Araldi et al (2013), Zhou et al (2015), and Santos et al (2018), mechanized operations are performed considering operational times to improve their field efficiency. In this line, Yousif et al (2013), Ma et al (2015), and Cervi et al (2015) claimed that field efficiency is the ratio between the effective time spent in harvesting operations and the total time that a machine remains in the field.…”

Brazil is the largest sugarcane producer worldwide. In mills, sugarcane crops are sprayed with agrochemicals using self-propelled, tractor-driven, and aerial hydraulic sprayers. As sugarcane spraying is regularly performed over extensive areas, the machinery to be used should be planned and dimensioned to ensure timely operations without overloading and at lower costs. Therefore, the current study aimed to analyze the operational and economic performances of different hydraulic sprayers to perform sugarcane crop control. As long as meeting our goal in field conditions would be difficult, we opted to develop a computational model, named as "TratoCana", using a spreadsheet and programming language. The model was used to assess economic and operational factors by generating scenarios and analyzing probable routine errors. In short, the results evidenced that initial value and operation speed are factors with the strongest impact on the costs of self-propelled sprayers and tractor-sprayer sets. Yet, the aerial application was mostly affected by fuel costs and crop row lengths. Moreover, the larger the spray tank volume, the lower the costs.

“…These times represent the field efficiency (FE) of the machine in the system. For Araldi et al (2013); Banchi et al (2008a); Barbosa et al (2015); Cervi et al (2015); Jokiniemi et al (2012); Oduma et al (2015); Linhares et al (2012); Ma et al (2015); Nascimento et al (2016); Neres et al 2012; Rivera et al (2012); Simões et al (2011) and Yousif et al (2013), this is the ratio between effectively used time and total time for equipment operation. The operational time Santos et al (2015a); Shamshiri & Ismail (2013) and Zhou et al (2015) and Çanakci et al (2011); Civelek & Say (2016); Santos et al (2015b); Santos et al (2014a) and Zaied et al (2014) have a participation in the equipment operational performance, which has a direct influence on the economic performance.…”

Brazil is the world's largest producer of sugarcane destined for mills. Spraying in sugarcane plantations is carried out in extensive cultivation areas and with self-propelled, tractor-driven, and aerial hydraulic equipment. For this, a good positioning of the replenishment pump of agricultural defensives close to the field where the spraying is carried out is necessary. However, it is desirable that the replenishment be carried out at short distances between the field and replenishment pump. This study aimed to assess the impact of the distance between the field and replenishment pump on the operational cost of hydraulic sprayers for sugarcane farming practices. Due to the difficulty in accomplishing the work and meeting the objective under field conditions, we decided to develop a computational model called "TratoCana" in a spreadsheet and programming language. The model was verified for possible routine errors, validated, and used in the analysis of factors and in the generation of scenarios. The results showed that the increased average distance between the field and replenishment pump has a negative impact on the operational and economic performance of the machine.
