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.
