SKL Field sprayer inspection

HomeAbout usWorkshop

We are a SKL (Foundation for Agricultural Quality Requirements) approved test station. This means that we meet the requirements set by SKL regarding test equipment and inspectors. This allows us to perform the legally required periodic inspection of your field sprayer. The inspections are carried out on the basis of a fixed uniform inspection protocol. After approval, we issue the official approval certificates on behalf of SKL, which are required by law.

Content inspection
During the inspection, the complete syringe is checked and a number of measurements are made. The purpose of this inspection is to map the maintenance status of the machine and to ensure that crop protection products can be optimally distributed. The inspection consists of the following components:

  • Check the booms for folding out and in; locking, height adjustment, balance correction, obstacle protection and quality of the structure.
  • Check the spray line with accessories.
  • Checking the condition of hoses, pipes, clamps, cap holders, caps for leaks, damage and fixing.
