Booms are identical for single-row and twin-row planters.
For single-row use, and if planting single-row on a
twin-row planter, half of the nozzles are shut off.

dealer-installed, because there can be multiple possible
applicator connection points, including:
• frame-mounted coulter applicator
• 25AP Series nut bar applicator
• seed firmer applicator
• press wheel dribbler

• Allow slack at the nozzle for nozzle removal and
orifice plate changes.
• Route to avoid planter moving parts which could
cause tubing damage.
• Route for continuous down slope - avoid low spots
in tubing.
• Allow slack along the route to anticipate coulter or
row unit vertical range of motion.
• Secure the tubing with tie-wraps only where
planter operations can’t cause tubing movement.
