Adjustment
bolt
" gap
Adjust spring loaded dry fertilizer drop tube/scraper periodically to
maintain " (3 mm) gap between drop tube and opener blade. If this
dimension is not maintained fertilizer may not drop in proper location.
Loosen scraper adjustment bolt. Slotted hole in scraper allows up or
down adjustment.
NOTE: DO NOT adjust spring preset dimension less than
9½" (24.13 cm).
NOTE: Excessive down pressure can cause planter frame up-lift
and affect machine performance. Planter frame should be 20"
(50.8 cm) from ground in planting position. Excessive down
pressure in loose soil conditions can cause openers to run too
deep and push dirt ahead of opener and may stop soil press
wheel and opener blade from turning.
Raise planter to remove weight from fertilizer opener. Turn spring
preset nut clockwise to increase and counterclockwise to decrease
down pressure. Adjust all rows to a similar setting. Minimal spring
pressure for acceptable operation is recommended. See chart for
spring length setting specifications.
Never place fertilizer closer than 2"
(5 cm) to row or seeds may be damaged.
NOTICE
Do not operate HD single disc fertilizer
openers at full down pressure tension on
rocky ground or disc blades will chip.
