Remove the pins restraining the seed box or bulk
hopper on the frame. (There are two lock pins one
each on diagonal corners).
Refer to Figure 27
Align the forks with the slots in the rear of the seed box or
hopper and slowly drive forward until forks are com-
pletely under the seed box or hopper.
Slowly lift the empty seed box or hopper from the planter.
Carefully install full seed box or an empty hopper on the
planter. Install box restraining pins in opposite corners.
Note: Bulk hopper frame has two sets of lifting points.
One set is for normal loading and is tubes. The oth-
er set is to allow picking it up from the side for plac-
ing in storage near a wall.
Tipping and Overload Hazard:
Never attempt to move a seed hopper while loaded. It exceeds
the lifting capacity of front end loaders and most fork lifts.
Always fill seed hopper with seed after it has been securely
placed back on the air box.
Note: It may be necessary to adjust the seal on top of air
box to get full contact with the bottom of seed box or
hoppers. This is a one-time adjustment.
