HERD ELECTRIC SPREADERS - VERY IMPORTANT SERVICE INFORMATION
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
BOLTS, REPOSITION, AND TIGHTEN, IN
REPOSITIONING, MAKE CERTAIN RATE GATE
OPENING IS EQUAL ON BOTH SIDES.
1. SET ADJUSTABLE RATE
GAUGE SO NUMBER “2-1/2”
SHOWS IN THE WINDOW.
OFF-ON SWITCH MOUNTS AT
A LOCATION CONVENIENT TO
OPERATOR.
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
SYSTEM. USE TO NARROW SPREAD
WIDTH TO MAKE APPLICATION.
PROTECTIVE
FUSE IS NOT
SUPPLIED
WITH WIRING
KIT.
IT IS NECESSARY
THAT MOTOR IS WELL
GROUNDED.

2. CHECK RATE GAUGE OPENING.
RATE GAUGE OPENING SHOULD BE
EXACTLY 1/8 INCH WIDE - EQUAL
ON BOTH SIDES.
3. IF ADJUSTMENT IS
REQUIRED, LOOSEN
RATE GATE ARM,
REPOSITION, AND
TIGHTEN.
