Landoll 7822 Series Operator's Manual page 22

OPERATION & MAINTENANCE
NOTE
If plugging occurs reduce the working depth until the
issue has been remedied. The HSL can produce a
"blacker" field in just a few inches of working depth, than
a convectional machine at approximately twice the depth.
NOTE
It is paramount that the 7822 track straight behind the
tractor. It is unimportant weather the machine run level or
not; typically the 7822 will run down hill to the front when
tracking straight.
Lateral Adjustment of Rear
Gang Assemblies
The front row of disc blades are fixed in position laterally.
They are designed to only rotate in place around their
torsion mounts.
• The rear row of blades are mounted on gangbar
weldments which can be adjusted laterally. The
gangbars are secured with 3/4-10 carriage bolts
extending through slotted brackets.

Figure 4-4: Lateral Adjustment of Gang Assemblies (1 of 2)
• The gang assemblies can be adjusted to the right or
left several inches. The gang bar adjustment
brackets, (Landoll Part Numbers 187631 and
195279) are designed to simplify adjusting the gangs
laterally.
• The HSL is set at the factory for an optimum floor cut.
As the disc blades wear down you will find it
beneficial to adjust the rear gangs to the machines
right side.
• When adjusting the rear disc gangs laterally, it is
best to first set the gang in the direction of the
desired movement so that the gangs do not hit
each other.
• While the typical row unit spacing is 10", the
spacing between the row units at the fold break is
approximately 10-3/8". Once the center section
rear gang assembly is adjusted and secured in
place, the wing rear gang assemblies should be
set relative to the center section rear gang
assembly.
• The wing rear gang assemblies should be
adjusted so the first row unit adjacent to the
nearest center section rear row unit is 10-3/8" on
center from it. See Figure 4-5
