Row Delivery Tubing
It might be necessary to replace this tubing before the
10 year life if the knife or tine end of the tubing is
damaged by harsh field conditions.
When replacing delivery tubing:
• Use the same length of tubing as removed. This length
is identical for all rows of a specific applicator model.
This is required to ensure equal rate at each knife or
tine from the flow divider.
• Coil excess length. Secure it to the rear tool bar at the
row. For wing rows, coil inboard of the row, so that the
coil is below the knife or tine when the applicator is
folded.
Row Vapor Tubing
This is a different (larger ID) tubing compared to the row
delivery and refrigerant tubing.
It might be necessary to replace this tubing before the
10 year life if the knife or tine end of the tubing is
damaged by harsh field conditions.
