Troubleshooting Guide
The Troubleshooting Guide, shown below, is included to help you quickly locate problems that can occur when using
your 7812 High Speed Landoll (HSL). Follow all the safety precautions stated in the previous sections when making
any adjustments to your machine.
Problem Cause Solution(s)
Disc plugs or pushes. Operating too deep. Shallow up the working depth.
Operating speed to slow. • Reduce tillage depth.
• Increase ground speed.
Excessive amount of dirt collected
on the discs. Field conditions too damp.
Foreign object caught between the
bland and shank, or blade and
frame. Remove the object. If this happens
repeatedly, consider installing
scrapers.
Disc hub bearing frozen. Replace the bearing and hub
assembly.
Rear depth gauge reel/roller bearing
frozen. Replace the bearing assembly.
Disc tracking to the left behind
tractor. Rear gangs too deep relative to the
front. Adjust (shorten) Top Link of 3-PT
Hitch.
Disc tracking to the right behind
tractor. Front gangs too deep relative to the
rear. Adjust (lengthen) Top Link of 3-PT
Hitch.
Leaving a valley on the left rear
corner. Leveling board too high; dirt flowing
beneath it. • Lower leveling board.
• Make lower extremity of the
leveling board parallel with the
ground.
Floor cut has grooves or ridges. HSL is not tracking straight behind
tractor. See previous guides on “tracking to
the left or right”.
Floor cut has ridges. Rear gangs out of adjustment
relative to the front disc unit. Adjust rear gang to the left slightly
less than the average width of the
ridge top.
Floor cut has grooves. Rear gangs out of adjustment
relative to the front disc unit. Adjust rear gang to the right slightly
less than the average width of the
groove bottoms.
Machine bounces in the field. Field conditions too rough for
operating speed. Reduce operating speed. Work
twice if necessary.
Floor cut irregular. Adjust rear gangs laterally.
Excessive down pressure on rear
reels/rollers. Decrease rear real down pressure
by shortening Ratchet Jack
Linkage.
Uneven operating depth Lower Links of 3-PT Hitch are
uneven. Adjust the lower 3-PT Hitch links to
be the same height.
