Levelling - Continued
Final Levelling
In order for any Air Drill to perform as intended, it
must be properly levelled. To properly level an Air
Drill, the final levelling must be done in the field
with ground conditions being firm and
unworked.
If the Air Drill is levelled in preworked, soft conditions,
the front may dip when working in harder conditions.
This causes the back row of shanks to work shallower
than the front and can result in rough, uneven field
finish and uneven seed depth which may result in
strips appearing in the crop.
Final levelling requires the following basic steps to
be followed:
1) Ensure that all stroke control collars are backed
off completely.
2) Rephase hydraulic depth system.
3) Lower the unit with the depth control circuit until
the points on the rear row of the main frame are
seeding at the desired depth.
4) When the desired depth is reached and with the
unit still in the ground turn down the stroke control
collars on
all the frames.
After the stroke control collars have been set:
5) Rephase hydraulic depth system. Pull the unit
100 feet at the desired depth at approximately
2 m.p.h.. Stop the unit in the ground.
Note: Only do one adjustment at a time.
6) Check the seeding depth of the points on the rear
row of the wing frames. Adjust short turnbuckle on
the wing frames to match the seeding depth of the
main frame. Lengthen the link to lower the frame.
7) Check frame side to side level. Adjust the packer
pivot brackets as necessary.
8) Check depth front to back on all frames. Adjust
the long turnbuckles. Lengthen link to lower the
front of the frame.
9) Pull the unit 100 feet at the desired depth
travelling at normal operating speed. Check
machine level and make any adjustments
necessary by repeating steps 5 through 8.
Note: Each operator is responsible for levelling
their Air Drill. As field conditions vary, fine
tuning is left to the operator’s discretion.
IMPORTANT
Final Levelling is
“VERY IMPORTANT”
It is suggested that the operator read
carefully and carry out the procedures
exactly as described.
Note: Any change in the depth setting can now
be done by adjusting all the stroke control
collars evenly across the whole unit.
