Fertilizer
The openers can be placed in three positions - stowed and
two operating positions to match field conditions.
NOTE: Opener will rest in positions 1 and 3, but will need
to be held in position 2 until pinned. Ensure opener is
supported prior to removing handle pin from position 2.
To change opener position, grasp opener with one hand
directly below coulter bearing. With free hand, remove lynch
pin and handle pin from opener. Pull up on opener slightly
and lift spring tee out of current location. Lower the opener
until the tee rests in the desired position. Install handle pin
into desired hole position, passing the pin through the spring
tee. Re-install lynch pin to lock in place.
Fertilizer depth is adjustable from approximately 2" to 4"
(5 to 10 cm) when planter frame is level and at proper 24"
(61 cm) operating height. Soil conditions will affect fertilizer
placement depth. Do not place fertilizer any closer than
2" (5 cm) to either side of row.
NOTE: The opener is designed to operate with the gauge wheel as the primary depth stop when in position 3.
In softer conditions, position 2 can be used to control depth using the gauge wheel as well as planter frame
to limit opener travel. In all positions, the opener will spring up when encountering a foreign object or hard
ground.
