4. Slowly unfold the implement. On the 45’ drills one in-
ner wing section will unfold about 45˚ and stop. The
outer wing section will then fold out straight. the inner
section will then fold out the rest of the way. When one
side has unfolded release and momentarily reverse
the lever. This will set a spool in the sequencing valve
so that the other wing will unfold when the lever is
again moved to unfold.
5. When the sections are unfolded, hold the lever until
the cylinders extend fully or else the wing flexibility will
be restricted.
Opener Operation
1. The floating hoe openers (shear bolt and spring reset)
both have an ability to “give” when they encounter ob-
structions. The spring reset hoe will trip when a large
obstacle is encountered. If the opener does not fully
return to position lift the drill out of the ground and al-
low the spring to pull opener back down.
For shear bolt openers you must replace broken shear
bolts to reset openers. Use only 5/16” x 3” grade 5
bolts only (Great Plains part number 802-131C).
2. Never back up with openers in the ground. Do not turn
sharply with openers in the ground. Doing so will plug
openers and may result in the machine damage.
3. Check periodically for plugged openers and hoses.
Leave the fan running and manually crank the calibra-
tion handle, see Setting Seeding Depth and Leveling
Front-to-Rear in the “Adjustments” section on Page
60. Look below each opener for seed. Do not crawl
among openers unless the gauge wheel locks are in
place and tractor is shut off with the key removed.
4. See Setting Seeding Depth and Leveling Front-to-
Rear in the “Adjustments” section, on page 60, for
information on setting seed depth and making opener
adjustments.
Unloading the Drill
1. Place the drill on firm, solid ground.
2. Turn off all tractor hydraulics to drill.
3. Remove auger storage lock pin and keep in a safe
place until done unloading.
4. Lift the auger latch handle until stop clears retaining
rod, refer to Figure 3-11. Pull auger out and away from
the drill being careful not to damage the auger tube on
the ladder steps.
5. Turn auger and place the hopper fully under the meter
unload door. It will be necessary to pivot support arm
fully to the front in order for hopper to clear ladder.
