Frame Mounted Coulter Adjustment: Coulters are factory

installed and are configured for in-row operation at knife or

tine shoe depth. They can be set for fixed or limited caster-

ing. Coulter depth can be adjusted per the following:

1) Loosen the U-bolt nuts (14) and slide the shaft (15) up or

down. Check the coulter-to-knife/tine alignment and re-

tighten the nuts.

2) Adjust the coulters to have a running depth at the bottom

of the knife or tine shoe. Roughly 3/4 inch below the applica-

tion depth.

3) For fields that have frequent sharp turns, coulters can be

adjusted to pivot at the pivot casting.

4) Loosen the jam nuts along with loosening the set screws

just enough to allow the casting to swivel and re-tighten the

jam nut.

Note: Do not remove the center stop screw.

Spring Knife Release Depth: Pull-type applicators have an

adjustable hydraulic down-stop controlling the tool bar height

which in return controls the knife depth. The knife is

designed to operate at a depth of 4 to 6 inches. Operating at

or below 8 inches is not recommended as a structure failures

can occur.

Reference Information:

Overall height of the tool bar base to knife shoe is (16) 30.25

inches (76.8 cm).

Liquid NH3 is release from the tube at (17) 3/4 inch (19 mm)

above the shoe base. For a precise release depth, subtract

this amount from the total knife depth.
