Mount Hopper or Bulk Seed Box
1. Prepare the air box, walkboard and seed structure
per the steps at “Prepare AirBox” on page 36.
Tip-Over Hazard:
Place or remove an 82 bu hopper only when empty. A full hop-
per can weigh over 5,000 lbs, which is above the lifting and
balance capability of most tractors and farm forklifts.
2. If mounting a bulk seed box, it may be easier to add
seed lubricant while the box is still at ground level.
See page 131 for amount to add.
3. If mounting a hopper, make sure slide gate is closed.
Refer to Figure 42 (arrow is planter-forward)
Note: Fork lift height capability required is:
5ft (1.5 m)
4. Determine the container and lifter orientation.
Although containers fit the seed structure at any ori-
entation, they can deliver seed only if the slide gate
is to planter-rear.
Although side placement is possible, Great Plains
recommends lifting from the rear of the seed con-
tainer, using the lower side tubes
. For side lifting
(typically for hopper storage), use the side fork
holes
. Do not lift from below the side tubes.
Tip-Over Hazard:
A full bulk seed box can weigh over 2500 lbs (1130 kg). Make
sure your tractor or fork lift is rated for and configured to lift
this weight. Do not let anyone stand under or in front of the
elevated seed hopper or bulk seed box.
Refer to Figure 43
5.
Place the hopper or bulk seed box in the seed struc-
ture.
6. Check the seal between the container and the air
box. The elastomer seal should be compressed by
approximately
1 ⁄
2
in (13mm). It may be necessary to
make a one-time adjustment to eliminate any air
gaps and achieve the recommended compression.
7. Secure the seed container to the frame using the
pins removed at step 9 on page 36. Placing these
pins at opposing corners provides the most stability.
8. Close the walkboard and secure with pin (page 35).
