Checking Drill Height
The drill is designed to operate with all sections of
the main tool bar 65cm above the planting surface, at
a planting depth of 3.8cm and a coulter (option)
depth of 5.1cm.
Measurement Error Risk
The drill must be fully lowered to field
position, with openers into ground, and
hitch height set before checking tool bar
height.
Tool bar height is measured to the bottom of the tool
bars on which the row units are mounted.
At the suggested default setting, the implement
frame is level with the ground during planting, and
the row units operate at their most consistent
planting depth.
Your crop, soil conditions, disk wear, and other
factors may create a need to use a different tool bar
height.
Tool bar height is set using combinations of the
spacer bushings (1) on the rods of the master lift
cylinders ahead of the implement center section,
described on page 58.
The wing end tool bar heights are controlled by slave
cylinders that stop retracting when the master
cylinders stop. Only weight transfer adjustment is
usually required for wing height, although eye bolt
adjustment is available.
When checking tool bar height:
1. Move the drill to similar planting soil conditions.
2. Check the tongue height (page 23).
3. Unfold and lower the implement (page 27).
4. Pull forward a meter or so to put the openers in
the ground.
5. Check the tool bar height across the drill.
6. If the center section is not at the desired height,
see “ Adjusting Tool Bar Height ” on page 58.
7. If wing tool bar heights do not match the center
section, this usually means that wing weight
transfer needs to be set or adjusted. See
“
Weight Transfer ” on page 59 before
considering an eye bolt adjustment (page 62).
