Front Coulter Adjustment
Front coulters are set at the factory to be directly aligned with the ripper shanks. This is important
for smooth residue flow around the shank. If the coulter is not properly aligned, loosen the 3/4in
hardware on the U-bolt and slide the mount bracket over until the coulter is aligned. Retighten
according to the torque specification chart in the “
General
” section of the “
Assembly Setup
” part of
the manual.
The coulter swivel stop setscrew should be pointed straight forward to ensure equal amounts of left
to right swivel.
The offset of the coulter stem should also be pointed straight forward. When the shanks reset
themselves after clearing an obstacle, the point swings forward and could hit the coulter if the offset is
not forward.
The vertical position of the front coulters should be adjusted according to the shank working depth.
To adjust the height of the coulter, simply loosen the (2) 5/8in setscrews, one at a time, that hold the
coulter stem in the mounting bracket as shown below. Caution should be taken when loosening these
setscrews as the stem can drop suddenly if it is not being supported. Once the setscrews are loose,
pickup/lower the coulter stem to the desired position and retighten the (2) 5/8 setscrews. Proper
procedure for tightening setscrews is to tighten to proper torque, loosen, then retighten to proper
torque. This allows the setscrew to “set” itself in the coulter stem and provides maximum holding
capability. (See Bolt Torque Chart) The chart below shows the stem height values for “A” and the
corresponding shank working depth values. Exact coulter position may differ from this initial setting
depending on how much coulter down pressure is needed for particular soil and residue conditions. If
coulter hub is dragging on residue or pushing dirt, then raise stem higher. If more down pressure is
needed to cut residue, then position stem lower. At any height, the coulter arm should not be
continuously against the upper limit stop or coulter/stem damage may occur.
