Brazil is one of the largest consumer of pesticides in the world, and to make these products reach the desired biological target are used different types of machines. In grain crops, the usual is the agricultural sprayers. Actually, there are different models of hydraulic sprayers, and maintenance of the machines inside the boundaries of acceptable quality is essential to ensure efficient spraying. The technical inspection sprayer is a way to monitor and assist the producers to keep these machines with acceptable error levels. Reinspections techniques were performed on machines that had participated in a diagnosis in 2008 and the results were contrasted with the aim of analyzing the possible evolution. Alongside this were audited in each property participating in order to verify compliance with regulatory norm 31 of the Ministry of Labor and Employment. Among the differences noted, there is an increase in the number of tractors under five years of use, which rose from 12.9% to 32.8%, a result of the supply of credit provided by public policies, such as the Program More Food which facilitated the acquisition of new machines. This development contributes directly to increased safety and comfort to the operator during the spraying process. The tractors that do not present any non-compliance increased from 13.04% in 2008 to 39.13% in 2011. Meanwhile, the 69 sprayers inspected in 2008, only 4.34% reached all requirements to be able to use this diagnosis. In 2011, sprays were 13.04% who met the requirements and were able to work without requiring any changes. That is, an improvement of three times the number of machines that were all evaluated items within the standards established by the project. Therefore, there was a great evolution in machines used for spraying. In relation to the care of rural properties for NR-31, none of them had full compliance with all regulatory requirements.
