Abstract
Considering that mechanized digging is an important stage in the productive chain of peanut, the studies related to the quantification of visible, invisible and total losses are still scarce, making it necessary to investigate these losses in order to obtain the operation control. In this context, the aim of this study was to evaluate the losses mentioned and the operational performance in the mechanized peanut digging related with five rotations in the tractor power take-off (PTO), verified by statistical control of the process (SCP). The experiment was carried out in tracks with eight replications for each treatment, making a total of 40 sampling points. There was no influence of PTO rotations in the visible, invisible and total loss averages during digging. The PTO rotation in 378 rpm (6.3 Hz) presents smaller variability of visible, invisible and total digging losses. The lowest fuel consumption variability and average speed are obtained with 486 rpm (8.1 Hz) and 378 rpm (6.3 Hz) PTO rotation, respectively. Key words: Arachis hypogaea L., harvest losses, vibratory treadmill, control charts.
Highlights
In Brazil, peanut (Arachis hypogaea L.) cultivation has expanded, influenced by mechanization, from sowing until harvesting and the São Paulo state is the greatest Brazilian producer; accounting for about 80% of production (Santos et al, 2013)

Summary
In Brazil, peanut (Arachis hypogaea L.) cultivation has expanded, influenced by mechanization, from sowing until harvesting and the São Paulo state is the greatest Brazilian producer; accounting for about 80% of production (Santos et al, 2013). Most peanut production occurs under highly intensive conventional tillage systems (Jackson et al, 2011). According to Jackson et al (2011), growers can experience yield loss when switching from peanut conventional tillage to strip-tillage in certain soil types due to the lack of an elevated bed at harvest time. In São Paulo it is common its utilization in areas of sugar cane renovation under conventional tillage systems. Peanut digging losses are inevitable, reaching higher levels with compacted soil and lower soil water content, with weak peduncle because of maturation excess, and premature defoliation caused by diseases (Roberson, 2008). The incorrectly determined peanut maturity at harvest can lead to high economic losses for farmers and the peanut industry as a whole (Rowland et al, 2006)
