Assembly and Operation Instructions
Earthway_M20 Manual PAGE 2
Assembly Instructions:
STEP 1: Unpack all parts from shipping carton to ensure no parts are missing. Refer to the exploded view.
STEP 2: Install the four (#9) 7/8” Tube plugs onto the ends of the two (#15) Frames with the help of a hammer or some
other tool.
STEP 3: Determine whether to mount on the front or the back of the luggage rack. Depending on whether the M20 is
mounted to the front or rear rack, you will need to install (#4) Control assembly to either the right (#11) or left (#15)
Frame tube to allow for use with the non-throttle hand. Wait until the unit is mounted to the Quad before installing the
Control.
STEP 4: Next install four 1/4-20 x 1-1/2” Carriage bolts (#12) through the Hopper assembly and then through ONE of
either side Frame and secure with 1/4-20 Hex Nut (#8).
STEP 5: Now position the M20 to the Quad and install the
remaining Frame member as outline above in STEP 4. Now
install the Control assembly (#4) to the Frame and secure with a
1/4-20 x 1-3/4” Carriage bolt (#13) and 1/4-20 Hex Nut (#8) and
tighten firmly to allow movement, but not allow the lever to
move unassisted.
Now install the M20 on your quad as outlined on the following
page.
WARNING
KEEP HANDS AWAY FROM ANY SPINNING OBJECT, SHUT-OFF PLATE, SHUT-OFF MECHANISM LINKAGE, AND THE
INSIDE OF THE HOPPER, EXTREME INJURY CAN OCCUR.

Assembly and Operation Instructions
Earthway_M20 Manual PAGE 3
HOW TO OPERATE SAFELY:
▪Read, understand, and follow all product label information provided on the material being applied.
▪An adjustable solid stop is provided that allows the operator to adjust to the desired opening position on the rate setting
control prior to operation of the vehicle. This allows repeatability to the stop without the need to look at the control
while operating the vehicle.
▪Establish the correct rate and then lock the stop in that position using the thumb wing nut on the setting control.
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.
MOUNTING INSTRUCTIONS:
Position the M20 on the vehicle so that the impeller is positioned to be able
to spin clear of any part of the vehicle, this will allow a full 180 degree
spread pattern. Secure the frame to the mounting location with the
enclosed J-Bolts at positions that will secure the spreader so that it will not
move when operating the vehicle. For best results mount the spreader so
that the impeller is as close to the vehicle as possible, but clears any parts on
the vehicle and place the J-Bolts as shown below.
Connect the black wire (ground) to the negative (-) post on the battery and
the fused wire to the positive (+) post on the battery.
If for any reason the impeller rotates counter clockwise,
reverse the battery connection of the spreader. Correct
rotation is clockwise.
SPREADER CALIBRATION INSTRUCTIONS:
▪Loosen stop on the gauge and set to #30
▪Open the lever to #30 and make sure that the shut-off is fully open
▪Loosen the cable clamp on the bottom of the hopper and slide the outer cable IN/Out until the shut-off is fully
OPEN. Tighten the cable clamp and retest.
▪Calibration is now complete
▪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, position 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.
