Airline Routing-Row Unit
Below is a suggested method for safely and securely routing the airlines from the air bag to the tees on the planter frame. These
are generalizations &
YOU SHOULD USE YOUR OWN BEST JUDGEMENT in routing airlines. DO NOT pass the airlines
between the rear of the parallel arm & the row unit. DO NOT pass airlines between the frame & the head plate used to mount the
row unit to the planter frame. These can act as both a pinch points & wear points. If necessary, use provided zip ties to keep
airlines away from pinch & wear points & sharp or rotating objects that may damage the airline.
Specific airline routing will be dependent upon: Row unit make & model (AGCO, CNH, JD, Kinze, etc)
, row unit spacing (15”, 20”,
22”, 30”, 36”, etc), parallel arm length, & other variables. RM units will have 1 up pressure & 1 down pressure air bag & RM/Coulter
Combo models will have 2 air bags on the bottom of the bracket for up pressure & a single air bag on top is for down pressure.
The 2 up pressure air bags will have airline connected together so the lift pressure trunk airlines will need plumbed to that Wye.
Airline Routing
The following pages are airline diagrams of different planter models. The wiring & tubing kit will have everything needed
to complete the installation.
Direction of flow is: Supply Tank

Water Separator Assembly

Control Box

Air Bags
All airlines will be 3/8”. Blue airline
should be used on all lift pressure air bags & black airline should be used on all down pressure air bags. Use the airline colors to
differentiate the lift pressure (Blue Airline) and down pressure (Black Airline) on the planter for troubleshooting & leak detection
indication. Route the airlines as efficiently and conveniently as possible.
