OPERATION
STEP 2. Set the coulter depth based on soil conditions, (i.e. tilth, stones or crop residue). For proper
operation of the Maverick Opener , the coulter must cut through crop residues including roots. For best
performance 3”-4” depth is recommended, maximum depth is 6”. Raising the blade helps to cut residue
rather than pushing it ahead and not cutting. Operating the blade deep puts the hub and mounting plates
close to the surface and may create plugging in heavy residue.
NOTE: When properly adjusted the Maverick Opener will ride up and over rocks and other obstacles if
present in the soil.
STEP 3. Set the depth of the knife by adjusting toolbar height and spring tension on the parallel arms.
STEP 4. Adjust the residue manager to move crop residue aside and not move any soil. Adjustments to
the residue manager may have to be made when changing field conditions and type and amount of residue.
ROW CLEANER DO’s AND DON’T’s
1. DO NOT move soil, Residue Managers are designed to move crop residue only.
2. DO NOT operate toolbar at slow speeds, ground speed affects how aggressive the spoke
wheels are; operate at sufficient speed (5-7 mph) to maintain good residue flow.
3. DO NOT expect 100% of crop residue to be cleared, it is not necessary and would
necessitate engaging the soil. The width of path cleared depends on ground conditions,
depth setting and ground speed.
4. DO expect to see wheels occasionally quit turning, indicates ideal (shallow) setting which is
not moving soil.
5. DO adjust toolbar frame height 24” and levelness. Very important to ensure Maverick
Opener will follow ground contours properly.
6. DO adjust Maverick Opener down pressure kit correctly to prevent excessive depth.
STEP 5. Adjust the Sealing Discs/Wheels. The width and height of the mound/berm depends on ground
conditions, depth setting, spring tension, blade angle and ground speed. A popular setting for the blade
adjustment is 8” at the rear of the blades, equal distance from the center of the row.
