INSTALLATION INSTRUCTIONS
STEP 5. Move the coulter assembly to the desired distance away from the seed furrow
2”-4”. Then fully tighten the ½” clamp bolts. Torque the bolts to 90 ft. lbs. NOTE: During
the season, check the tightness of the clamp bolts daily.
IMPORTANT: Never locate the opener to place fertilizer closer than 2” to the row.
STEP 6. Setting the height of the coulter assembly, loosen the 5/8” setscrew and raise or
lower the coulter/shank assembly to the desired height. Tighten the setscrews to hold the
coulter/shank assembly in place. NOTE: Field adjustment of the shank position will be
required to accurately place the fertilizer at the desired depth. Factors affecting fertilizer
depth: toolbar height, shank adjustment, gauge wheel adjustment, spring pressure
adjustment, and soil tilth. When the coulter shank is adjusted to the desired height, triple
tighten (tighten, loosen, tighten, loosen, tighten) the 5/8” setscrews so that the cup point is
properly seated into the coulter shank.
NOTE: Regularly check the tightness of the setscrews.
