2) General Information
• Depending on the type of crop and the height of the plants we recommend a distance
between the lifters of 1 foot (30cm) or every fourth guard tip
• The outside lifters need to be at least 1 foot (30cm) apart from the outside walls.
MacDon recommends the fifth guard tip
• To guarantee a proper function and avoid breakage always ensure the correct working
position of the lifters
• Please be aware of different lifter positions after resetting the header angle
• For proper mounting of the lifters please follow Step #3 of the instruction manual
