Tool Bar Height Adjustment
Center section tool bar height is set by the tractor hitch.
Lift-assist spacers (page 43) must be selected and in
place to assure front-to-back level.
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 92).
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 applicator (page 56).
4. Raise the applicator to bring the wing coulters off the
ground, and the wings slightly above level.
Refer to Figure 63
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 fold/lift circuit to Float.
8. Use the 2-point hitch to lower the applicator until the
center section coulters are just at ground level.
9. Check frame front-to-back level and adjust spacers
(page 43) as necessary.
10. Adjust the gauge wheel heights to bring the wing
coulters to the same height as the center section
(just above the ground).
11. Measure the length of exposed gauge wheel tube.
12. Crank the wheel up by the desired coulter depth
(exposed tube length becomes length minus the
coulter depth). Capture this setting by re-inserting
and securing the pin .
13. Crank the wheel up until the tube solidly contacts the
pin. This transfers wheel loads to the pin, and not to
the crank.
14. At the center section, measure the tool bar height
above the ground. Operating height is this distance
less the desired coulter depth.
15. Pull forward, lowering the 2-point hitch to operating
height. Set a stop on the 2-point circuit to capture
this height.
16. Adjust weight-transfer (page 92) to hold wings level
at this coulter height for these field conditions.
Equipment Damage Risk:
Use the pin . Crank the tube up against the pin. Wheel loads
transmitted to the crank can damage the crank.
Note: Turn crank clockwise to raise applicator (lower
wheel), and counterclockwise to lower applicator
(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 coulter
depth prior to setting for maximum.

Note: Prior to folding, fold the jack handle down
alongside the jack body. This retains the jack
handle and prevents it from hitting the fertilizer
tanks when folded (if so equipped).
