M3B ELECTRIC MODEL POWER SPREADER/SEEDER
MOUNTING, SERVICE, AND SAFETY INFORMATION
IMPORTANT NOTICE!
The Model M3B seeder is designed to be mounted to farm tractors, pickup trucks, the Herd T12-300
flotation trailer or turf trucks.
We do not recommend that this seeder be mounted to a lawn tractor, garden tractor or all terrain vehicle
(ATV) due to the size of this seeder. If you purchased this seeder to mount to a lawn tractor, garden
tractor or ATV, please contact your dealer or the Herd Seeder Company.
The Model M3B seeder is powered by a 12 volt D.C. motor which is negative (-) ground. Any attempt to
run the motor with any device or battery other than a 12 volt D.C. battery could result in injury to the
operator or cause damage to the motor.
Any questions about the mounting of or the safe operation of this seeder should be directed to the Herd
Seeder Company by phone at 574-753-6366.

MOUNTING INSTRUCTIONS
Mounting M3B Seeder To Farm Tractors
Place the main frame (#T303) of the seeder on the drawbar (hitch) of the tractor and attach
it with the 5/8” x 2-1/2” hex head bolt provided. This bolt will screw into the bottom of the
main frame. (A 5/8” hex head nut is welded inside the main frame.) Attach one brace rod
(#T203) to each side of the hopper by bolting the small hole end of the brace rod to the hole
in the corner brace (#T205). Then attach the large loop end of the brace rods to a solid bolt
on the tractor frame or axle housing. Push the top of the hopper toward the tractor and
tighten the brace rod clamps to put slight tension on the brace rods. Now follow the wiring
diagram on the next page to complete the installation.
If the tractor has a category 1 three point hitch, we have available as an option the lower
cross bar (#T505) and the upper three point hitch bracket (#T393).
Mounting M3B Seeder To Pickup Trucks
This seeder can be mounted to a pickup truck by three different methods. The first method
is by using the brace rods (#T203) that are provided with the seeder as standard
equipment. Place the main frame (#T303) of the seeder on the rear bumper of the pickup
making sure that the bottom of the frame is over the hole provided in the bumper. Using
the 5/8” x 2-1/2” hex head bolt provided, insert it from the bottom of the bumper up through
the hole in the bumper. Then screw it into the 5/8” hex head nut that is welded inside the
seeder main frame. Now attach the small hole ends of the two brace rods (#T203) to the top
of the hopper using the holes provided in the corner braces (#T205). Attach one brace rod
to each side of the hopper. Then attach the large loop end of the brace rods to a solid spot
on the pickup bed or side rails. If there are not any existing holes, you will have to drill
them to complete this installation. Now follow the wiring diagram on the next page to
complete the mounting.
The second method is to use the optional pickup mounting rails (#T502). These mounting
rails allow the seeder to be mounted to a pickup without drilling holes for the brace rods.
The pickup must have stake pockets at the rear of the pickup bed for the optional mounting
rails to be used. Complete instructions are furnished when this option is ordered.
The third method is the optional 2” receiver mount hitch (#T700). This mounting requires
that the pickup already has a 2” receiver attached. Complete instructions are furnished
when this option is ordered.
Mounting M3B Seeder To T12-300 Flotation Trailer
The optional T12-300 Flotation Trailer is available from Herd Seeder Company to mount
the M3B Seeder using the brace rods (#T203) which are furnished standard with the
seeder. Complete instructions are furnished when this option is ordered.

CORRECT SPREADING SPINNER LOCATION IN RELATION TO HOPPER BOTTOM LOCATION
VERY IMPORTANT FOR UNIFORM SPREADING
1. THE DISTANCE FROM THE LEAD EDGE OF THE
FLOW SPOUT TO THE CENTER OF THE
SPREADING SPINNER SHAFT SHOULD BE
EXACTLY 2-15/64 INCH.
2. IF DIMENSION IS OTHER THAN 2-15/64 INCH,
LOOSEN THE TWO BRACKET MOUNTING

THE ABOVE DIAGRAM ILLUSTRATES HOW TO WIRE THE
HERD M3B SEEDER WITHOUT THE TR-75 VARIABLE
RESISTOR WHICH IS OPTIONAL. IT IS VERY IMPORTANT
TO REMEMBER THAT THE SEEDER MOTOR MUST BE
GROUNDED BACK TO THE (-) NEGATIVE SIDE OF THE
BATTERY. THIS CAN BE ACHIEVED BY CONTACT OF THE
SEEDER MOUNTING BRACKETS TO THE FRAME OF THE
VEHICLE THE SEEDER IS MOUNTED ON. SOMETIMES
WHEN THE MOUNTING BRACKETS DO NOT CONTACT
THE FRAME OF THE VEHICLE SOLIDLY A SEPARATE
GROUND WIRE MUST BE RUN FROM THE SEEDER
FRAME TO THE FRAME OF THE VEHICLE. IF THE MOTOR
WILL NOT RUN, FIRST CHECK TO SEE THAT IT IS
GROUNDED PROPERLY.
OFF-ON SWITCH IS NOT
USED. RHEOSTAT HAS
BUILT-IN OFF-ON.
RHEOSTAT MOUNTS ON TRACTOR DASH.
USE TR-75 RHEOSTAT ON 12 VOLT

A. With limitations, spread widths are determined by:
1. Volume Density/Particle size of fertilizer, seed,
granular material.
2. Speed of whirling spreading disk.
3. Mounting height (some materials only).
B. NOT ALL MATERIALS HAVE THE SAME
SPREADING CHARACTERISTICS as shown in
“SPREADER MOUNTING ANGLE TO TRACTOR”
column of chart.
Arrow indicates proper mounting angle (if required)
for individual materials.
For equal spread on both sides of Spreader/Seeder,
point Spreader/Seeder in the direction of the arrow.
OR, if “off-center” spread is indicated, Spreader/Seeder
may be mounted “off-center” on vehicle, OR allowance
may be made in the operation of the vehicle.
C. Electric Spreader/Seeder mounting angles are for
clockwise rotation of spreading disk. If an electric
motor with counter-clockwise rotation is used, use
reverse arrow directions.
D. CHECK CALIBRATION OF SPREADER/SEEDER
before using. Lever sitting #2-1/2 should show exactly
1/8” opening - with opening equal.
If required, adjustment may be made by loosening
allen screw on “arm” connecting feed plate to control
lever, adjusting and tightening.
E. The distance from the CENTER of the spreading
disk to the EDGE of the feed flow spout should be
exacly 2-15/64”. Adjustment may be made by loosening
the two bracket bolts, adjusting bracket and
tightening bolts.

IMPORTANT!
Afterspreading salt, ice melteror

be washed thoroughly with waterto
remove any corrosive residue. Special
care should be takento prevent water
from entering the motoraround the
motorshaft. If youuse a high

do not spray the pressurized water
stream directly at the motorshaft or
youmight displace the grease from

motorbearing.
The electric motorissealed and no
maintenance canbe performed except
to wipe off any residue onthe exterior
of the motorhousing.

SERVICE INFORMATION
The M3B Seeder uses a 12 volt D.C. electric motor that is a negative (-) ground. Therefore,
the orange wire from the motor must be connected to the positive (+) terminal of the 12 volt
battery being used for power. The frame of the seeder must be mounted securely to the
vehicle to act as the ground. If the frame of the seeder does not contact the frame of the
vehicle and make the ground complete, a separate ground wire must be added. This can be
done by using a 14 Ga. automotive wire (not furnished with the seeder) and connecting it
to the bolt on the seeder and a secure place on the frame of the vehicle or directly to the
negative (-) terminal of the battery. Every M3B Seeder is tested before it is shipped; so if
the motor does not operate, the problem is most likely the ground is not complete.
When fertilizer or salt is used in the seeder, the hopper should be washed with water to
remove the corrosive residue. Special care should be taken to prevent water from entering
the motor around the motor shaft and the terminal wires. NOTE: A plastic sack makes a
good motor covering to keep water out while washing the seeder.
To remove the spreading spinner (#T221) and eccentric shaft (#T213) from the electric
motor, loosen the allen head set screw in the motor coupling (#T211). This coupling may be
removed from the eccentric shaft by turning the coupling in a clockwise direction or to the
right. Both the coupling and eccentric shaft are left hand thread and turning to the right
or clockwise will loosen them.
