Transport
Transport to Field Position
• Position machine on level ground.
• Stop tractor, and engage park brake.
• As a precaution, check surrounding area to be sure
it is safe to lower wings.
• Extend main frame depth cylinders. (Fully
extending the packers)
• Position lock lever in forward position, unlatching
wing rest latch.
• Remove wing transport lock strap pins and swing
the transport wheels gravity lock up. Do not walk
under raised wings.
• Operate the wing lift hydraulics. First, lowering the
wings fully. Secondly, raising the transport wheels
fully. Never raise or lower wings when moving.
• Ensure wing lift cylinders are fully extended.
• Remove transport lock pin and castor lock pin from
main frame gauge wheel.
• Operate depth control hydraulics, to raise machine
fully, holding the hydraulic lever for several seconds
to phase the system.
• On the Five Frame Models ensure that the inner
wing foot has retracted.
Note: Wingsmustlowerfullybeforethetransport

Levelling
Initial Levelling
1) Initial levelling should be done on a flat, level
surface, similar to that of a concrete oor.
• Adjust packer pivot brackets to bottom of adjusting
slot.
a) Regular Seed Openers
(Lower Height Setting - Field Clearance Settings)
• Adjust the short turnbuckles length to 19 3/8” from
pin centre to pin centre.
• Adjust the long turnbuckles length to 101 1/2” from
pin centre to pin centre.
• 55 ft and 60 ft Inner Wing adjust the long
turnbuckle length to 100 3/4” from pin centre to
pin centre.
b) Double Shoot/Knife Openers
(Higher Height Setting - Field Clearance Settings)
• Adjust the short turnbuckles length to 18 1/8” from
pin centre to pin centre.
• Adjust the long turnbuckles length to 101 1/2” from
pin centre to pin centre.
• 55 ft and 60 ft Inner Wing adjust the long
turnbuckle length to 100 3/4” from pin centre to
pin centre.
2) Lower the unit with the depth control circuit until the
points are about 1” above the ground.
3) Check the main frame side to side level. Adjust the
packer pivot brackets as necessary.
4) Adjust the main frame front to back with long
turnbuckle link so the front row of points is about
1” lower than the back row of points. Lengthen the
link to lower the front of the frame.
Note: Framesshouldbepresetwitha1”difference
front to back due to the tendency of the
packerstosinkmoreinworkedsoilthanthe
front wheels. This setting is approximate
andmayhavetobeadjusted,dependingon
soilconditions.
5) Adjust the wing frames side to side and front to back
in the same way as the main frame (Step 3 and 4).
6) Adjust the wing frames to the same height as the
main frame, by adjusting the short turnbuckle link.
Lengthen the link to lower the frame.
Important
Keep tire air pressure at the listed
specifications to achieve and maintain
properlevel.

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
nal levelling must be done in the eld with ground
conditions being rm 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 eld
nish 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.(See

Lower Height Setting
a) Mount main frame gauge wheel in lower holes.
b) Mount packers on main frame in lower holes.
c) Place spacer on the bottom of wear plate.
• Wear plates are located on the wing gauge wheel
lower link.
• Wear plate should contact the hitch truss in the
middle as shown.

Hydraulic Depth Control System
Three Section Models
The hydraulic depth control system is a series system.
To lift the Maxim Air Drill, hydraulic uid is forced into
the butt end of cylinders 1. This causes the piston rods
to extend, pivoting the packers and the gauge wheel
down. This causes the main frame to raise.
Simultaneously, hydraulic uid is forced from the gland
end of cylinders 1 to the butt end of cylinders 2, causing
them to extend, pivoting the packers and gauge wheels
down. This causes the wings to raise.
Finally the uid exits the gland end of cylinders 2 into
a common line and then to the tractor.
29 ft. and 34 ft. Models
To lower the Maxim Air Drill, hydraulic uid ows
through the cylinders in the reverse direction to that
described above, until the stroke control collars seat
rmly on the gland end of the cylinders. This causes
the ow of oil from the tractor to stop.
With the stroke control collars firmly seated, the
cylinders will hold this working depth until the tractor
hydraulic controls are activated to lift the Maxim Air Drill.
Note: A one-way flow restrictor valve is
incorporated into the hydraulic system to
maintainapositiveoilpressure.
39 ft. Model
The 39 ft. unit has pilot operated check valves
incorporated into the depth control system.
Once the tractor hydraulic lever is released the pilot
operated check valves close, isolating the Maxim Air
Drill hydraulics from the tractor.
