Depth Stop Adjustment (Manual)

The operating depth of the disc is controlled by a
single-point depth stop. The stop is located at the center
front of the machine.

1. Adjust the depth stop by turning the handle in
(clockwise) to increase operating depth (See
Figure 4-17.) Turn the handle out
(counter-clockwise) to decrease operating depth.
One turn will equal approximately 3/16" adjustment in
depth.
2. The gauge on the side of the depth stop tube gives a
reference for depth setting. The "A" setting refers to
maximum operating depth.
IMPORTANT
For maximum operating depth, the lift wheels must
be in contact with the ground and carry some of the
machine weight. Raising the lift wheels off the
ground, permits uncontrolled depth of each frame
section and does not allow the leveler to function
properly.

Electronic Depth Control
Adjustment
The optional Electronic depth control is available to work
with John Deere 7720, 7820, 7920 (IVT transmission
only), 8000, and 9000 series tractors equipped with the
TouchSetdepth Control. This allows the operator to set
one or more depth control stops from the tractor.
TouchSetdepth control must already be installed on
the tractor to be able to use the electronic depth control.
1. To be able to use the Electronic Depth Control, adjust
the connecting linkage between the depth control
lever and the depth stop mounting plate to 5-1/2"
length (See Figure 3-6.)
2. Rotate the manual depth stop handle clockwise to
fully retract the hydraulic depth stop. This will allow
the electronic stop to function properly without being
stopped inadvertently.
3. Connect the electronic depth control harness to the
electrical connector at the rear of the tractor.
4. Read and follow the tractor manufacturer's operating
manual for operating and setting the depth from
within the tractor cab.
