3-Point Height
This applies to 3-point applicators only. See page 68 for
2-point and page 70 for pull-type.
Center section tool bar height is set by the tractor hitch.
3-point hitch must be adjusted to keep implement frame
level front-to-rear.
Wing end tool bar height is set by independent gauge
wheels on each wing end. Wings are maintained at level
in the field with the weight-transfer system (page 71).
1. Move to smooth level ground with soil as similar as
possible to field conditions. Set tractor brakes.
2. Determine the desired coulter depth.
3. Unfold the implement (page 51).
4. Raise the implement to bring the wing coulters off
the ground, and the wings slightly above level.
Refer to Figure 50
5. At each gauge wheel, use the crank to remove
tension at the pin . Remove the pin.
6. Use the crank to extend the wheels far enough to
keep the wing coulters off the ground.
7. Unfold the wings until the gauge wheels are on the
ground. Set lift/fold circuit to Float.
8. Use the 3-point hitch to lower the implement until the
center section coulters are just at ground level.
Check front-to-rear level.
9. Adjust the gauge wheel heights to bring the wing
coulters to the same height as the center section
(just above the ground).
10. Measure the length of exposed gauge wheel arm
tube.
11. Crank the wheel up by the desired coulter depth
(exposed arm tube length becomes length plus
the coulter depth). Capture this setting by
re-inserting and securing the pin
.
12. At the center section, measure the tool bar height
above the ground. Operating height is this distance
less the desired coulter depth.
13. Pull forward, lowering the 3-point hitch to operating
height. Set a stop on the 3-point circuit to capture
this height.
14. Adjust weight-transfer (page 71) to hold wings level
at this coulter height for these field conditions.
Note: Turn crank clockwise to raise implement (lower
wheel), and counterclockwise to lower implement
(raise wheel).
Note: At maximum height, the coulters are off the
ground. This configuration is useful for unfolded
parking, storage and service.
Make a record of the setting needed for field
height prior to setting for maximum.
