TYPICAL DOWN-PRESSURE SETTINGS
No-till, Heavy Residue Raised or Minimum (100 psi)
Tillage Strips (Anhydrous, In-Lining Ripping), Medium Residue 200 psi
Tilled Soil, 0" to 3" Ridge and Valley, Medium Residue 300 psi
Tilled Soil, 3" to 6" Ridge and Valley, Medium Residue 400 psi
Tilled Soil, Heavy Ridge Ridges, Minimum Residue Up to 500 psi

RESIDUE PROBLEMS AND SOLUTIONS
PROBLEM SOLUTION
Bunching or Raking Residue Reduce psi or adjust gauge wheels to deeper setting to
create more loose soil to mix with the residue.
Loping or Bounce in Module Retension modules
Wash Boarding Change cover board angle by changing turnbuckle or
reducing psi.
Not Filling in Valleys Increase psi or adjust gauge wheels to deeper setting to
create more loose soil to mix with the residue.
Streaking of Residue Most likely due to module overlap - shorten modules or
move the front of the module mounting u-bolt forward j3" -
4". This will also reduce overlap.
Clipping the end teeth on each harrow section will also
reduce the overlap and reduce streaking.
Harrow Not Level because of High Down Pressure on the
Cover Boards Harrow frame does not need to be level for successful
operation. When running the harrow just make sure that
reel is running 1/2 - 1-1/2" deep, rolling harrow assembly
is rolling over the ground and that cover board
down-pressure is appropriate for the cover conditions.
