Earthway M20 12-Volt ATV Mount Broadcast Spreader - Manual (Page 4)

OPERATING INSTRUCTIONS:
Before filling hopper, become familiar with the operation of this spreader. (Practice the following steps)

Turn the motor switch to the ON POSITION, so that the impeller is turning before going on to the next step.
 While driving forward pull the lever back to the stop, this opens the shut off plate on the spreader.
 To stop the flow of material, Push the lever to “0” or closed position, then turn the motor off when finished.
 When finished empty any remaining material from hopper.
 Thoroughly wash spreader and allow to dry before storing. A light coating of oil will help prevent corrosion
of all metal surfaces.
CALIBRATION INSTRUCTIONS:
 Loosen set-screw on gauge cable and
 Set adjustment dial to “0” Closed
 Activate switch to extend to the “STOP”
 Slide Calibration Bracket to ensure shut-off is closed
 Calibration is now complete
IF RATE SETTINGS ARE NOT AVAILABLE USE THE FOLLOWING PROCEDURE TO CALCULATE THE SETTING:

Determine how much material is to be applied per 1,000 sq/ft.
 Measure off a distance of 50 feet, preferably on a paved surface such as a parking lot.
 Weigh out enough of the material to be applied to fill the hopper at least half full. Record the weight for
future use.
 With the unit mounted on the vehicle and the hopper at least half full of the material to be spread, posi-
tion the vehicle far enough before the beginning of the 50 foot test area so that the vehicle will achieve the
desired speed before you reach the starting line.
 Set the rate setting stop at a position that you feel would be an appropriate setting.
 Start the vehicle in motion and as you cross the starting line (of the 50 feet) move the rate lever to the open
position against the stop. Take care to be aware of what is going on around you maintaining control of the
vehicle.
 Continue from the starting line with the unit spreading the material. As you cross the finish line move the
rate lever to the closed position.
 Stop the vehicle and note the width of the spread path that was just completed.
 Return to the start point and empty the remaining material from the hopper into your weighing container
and re-weigh.
RATE SETTING WORKSHEET
Desired Application Rate (lbs/1,000 sq ft) _____________
To determine the desired application rate divide the area (sq ft) the bag should cover by the weight of the bag,
then multiply by 1,000. (Example: 5,000 sq ft / 25 lbs = .005 x 1,000 = 5)
_________ Weight of Material Placed in Hopper
- ________ Weight of Material Left in Hopper
= ________ Weight of Material Used
50 Length of Test Area (50 from previous page)
x ______ Width of Spread Area
= _______ Total Spread Area
Divide the Weight of Material Used by the Total Spread Area = _________lbs\sq ft
Multiply the lbs\sq ft times 1,000 = ________lbs\1,000 sq ft
Compare the results of your test to the desired application rate.
Adjust the rate setting stop accordingly and run through the test again.
Repeat this process until you have achieved the desired application rate.
