Instructions for Assembly, Mounting,
Operating, and Maintenance.
MODEL I-258 General Instructions
1. For Normal broadcasting of seeds, this model I-258 seeder requires no changes. It was
assembled at the factory for this purpose.
2. This model may be mounted via one of our mounting kits (i.e. #660 2” receiver hitch, Carton
JPH-1, etc).
3. An electronic speed control (#812) may be purchased as an option to control the width of
the spread of material. This will allow the spread pattern to be narrowed by a slower fan
speed.
4. To center the spread pattern, pivot plate #802SI can be rotated left or right. To do this,
loosen the two capscrews holding the pivot plate to the base of the seeder. While facing the
hopper and looking at the Herd Seeder Co. decal, if the spread pattern of the material being
spread is heavy to your right, then move the pivot plate to a lower letter. If the spread
pattern of the material is heavy to the left, move the pivot plate to a higher letter.
5. Be sure the battery charge is up and the generator/alternator is operating efficiently, so that
the broadcaster will operate at the necessary RPMs. The motor will use approximately 8 to
10 amps when spreading.
6. This unit is not recommended for fertilizer or salt as the corrosive material must be kept off
the electric motor.
ASSEMBLY INSTRUCTIONS
1. Place the broadcaster motor side up, on a level surface for assembly.
2. Turn the handle (part #729) around toward the seeder base and remove the flathead screw
and jamnut. Place flathead screw first through the hole in the seed gate linkage, then
through the hole in the handle. Tighten with the jam nut until snug. Make sure the jam nut is
up, facing you, and not too tight, as it must pivot at this point.
3. Check the opening gauge control plate (part #803S) for correct fit. It is possible the gauge
could have been bent in shipping. This gauge is used to set the seed gate opening opening
width to regulate the amount of seed flowing through the seed gate onto the spinner fan.
The seeder is now ready to be mounted.
MOUNTING #794 SWITCH
1. The push-pull switch (part #794) can be mounted next to the driver’s seat, in a convenient
spot. It can also be mounted next to the broadcaster on one of the remaining holes on the
cross angle iron.
2. When the optional #811 Electronic Speed Control is used, FOLLOW THE INSTRUCTIONS
SUPPLIED WITH THE #811 KIT EXACTLY. Failure to follow instructions exactly will result
in motor failure and will void the warranty.
WIRING INSTRUCTIONS
1. Run the #754 wire from the motor terminal to the switch or rheostat, then run a wire from
the switch or rheostat to the positive (+) battery terminal. Use 14 gauge wire or heavier.
2. You can use the battery clamp #755 to connect the positive (+) wire from the switch or
rheostat to the positive (+) battery terminal for convenience.
3. A second ground must be run between the frame of the seeder and the frame of the
vehicle.

ADDITIONAL TIPS AND TROUBLE-SHOOTING
1. Causes of packing material in the bottom of hopper:
Filling unit at barn then driving to field
Using material that has collected moisture from storage, or material being used on
extremely damp days.
Use of poor grade material
Using hopper extension when material is not used at a fast rate
2. Cause of material blowing on operator during spreading:
Unit mounted too high about ground. This will cause the fan draft to pick up object
tionable odors from material, including dust, and carry them back to the operator.
Using material that is too dusty
Driving into wind. You should operate vehicle at a slight angle so that the material
blows to one side
3. Hopper extension is recommended for oats only.
4. If the motor does not operate correctly, check connection, battery, generator, and
switch. Make sure unit is grounded securely to vehicle.
5. The opening must be opened wider for faster speeds in MPH of vehicle, and set nar-
rower for slower speeds, to ensure proper amount of material on the ground.
6. If spread is too far to the left when facing broadcaster, move pivot plate so that the
opening aligns with a higher letter. If spread center is to the right, move pivot plate so
that the opening aligns with a lower letter. Be sure to tighten pivot plate capscrews after
adjusting.
7. The poorer grade of material, the narrower the spread and more difficulties will be en-
countered. Therefore, we recommend you use good, dust-free material.
MAINTENANCE
1. Store this model in a dry place so that the motor will not draw dampness. Be sure to
check motor so that it runs freely when it is to be used next. Run broadcaster empty a
few minutes before using after long periods of storage.
2. Clean inside of hopper and seed plate with a dry or lightly dampened clean rag.
3. Do not allow moisture/water to set on the motor shaft. This can cause internal damgage
to the motor and will void warranty.

The above chart is a reference only. The width of the spread varies according of the
quality and weight of the seed/material, fan speed, and wind conditions. All widths
given above are conservative. After making one run through your field, check spread
and check battery/grounding connections.
When measuring opening width, measure from the inset of tooth on the seed gate,
not from the tip of the teeth.
CAUTION:
When spreading bahia grass, teeth must be removed from seed gate for even feeding.
For every 1/16” increase in opening, the amount going through the opening will
increase approximately 100% over the last setting.
