Cleaning the field sprayer on the field

Clean the spray liquid circuit, the spray lines, and nozzles while driving on the field, as cleaning water is applied intermittently. The implement can be cleaned in the farmyard, if a collecting facility, such as a biobed is available.

There is a distinction between fast cleaning and intensive cleaning:

  • Perform quick cleaning daily.

  • Intensive cleaning must be performed before a critical agent changeover or before taking the implement out of service for a longer period of time.
