specification.
Tipping and Overload Hazard:
Place or remove a hopper only when empty. A full hopper can
weigh between 5000 and 10000 lbs (2700-4500 kg), which is
above the lifting and balance capability of most tractors and
farm forklifts.
1.
Move the planter to an area of level ground and
sufficient room to maneuver a tractor or fork-loader.
2.
Unhitch tank cart if present.
3.
Disconnect hopper level sensor (if installed).
4.
Remove the pin
securing the left end of the
walkboard to the ladder assembly.
5.
Swing the walkboard open, and secure it at full open
with the keeper
.
6.
Raise the planter. This causes the rear transport
wheels to move forward, providing closer access for
the lifter.
7.
Back up the planter about 3 ft. (1m). This causes the
rear transport wheels to caster forward, further
reducing the reach required for lifting.
8.
Turn off the seed box fan.
9.
Put the towing tractor in Park. Shut off engine.
Remove key.
10. Close the slide gate at the base of the hopper or
seed box.
11. Remove the two pins
, at opposite corners, used to
retain the seed box or hopper. Remove these pins
even if no container is presently mounted.
12. Align the lifting forks with the slots in the rear of the
seed box or hopper. Slowly drive forward until the
forks are completely under the container.
13. Slowly lift the seed container above the bracket, and
back away from the planter.
14. Lower the container to the ground for exchange with
the next seed container.
a. The 150 bu. hopper is incompatible with on-board fertilizer tanks.
