3. SAFETY PRECAUTIONS

CAUTION: BEFORE ATTEMPTING TO OPERATE THIS SPREADER, READ AND STUDY THE
FOLLOWING SAFETY INFORMATION. IN ADDITION, MAKE SURE THAT EVERY INDIVIDUAL WHO
OPERATES OR WORKS WITH THE SPREADER, WHETHER FAMILY MEMBER OR EMPLOYEE, IS FAMILIAR
WITH THESE SAFETY PRECAUTIONS.

Require anyone who will operate this spreader to read and completely understand this Owner’s Manual. Give
necessary instructions!

DO NOT operate, service, inspect or otherwise handle this spreader until all operators have read this Owner’s
Manual and have been properly trained in the intended usage of the spreader.

Do not allow minors (children) or inexperienced persons to operate this spreader.

If the spreader becomes clogged, shut off the tractor engine and allow all mechanisms to stop. Disconnect PTO
shaft and hydraulic hoses (relieve hydraulic pressure). Then, clean or work on the spreader as required.

Always shut off power and disconnect PTO drive shaft and unhook hydraulic hoses (relieve hydraulic pressure)
from tractor to prevent accidental startup or unexpected movement before working on machine.

Do not clean, adjust, or lubricate while spreader is in motion.

Make sure all hydraulic fittings are tight and that all hoses are in good condition. Hydraulic fluid escaping under
pressure can have sufficient force to penetrate skin and cause serious injury. Never investigate for hydraulic leaks
by using a part of the body to feel for escaping fluid.

Inspect when first delivered and regularly thereafter. Verify that all connections and bolts are tight and secure
before operating.

Know how to stop the spreader before starting it!

Do not operate until all shields, covers and guards are in place.

Make certain everyone is clear of the spreader before applying power.

Keep hands, feet and clothing away from moving parts. Loose or floppy clothing should not be worn by the
operator.

Stay well clear of the spreader’s rear discharge spinners while operating.

Do not step up on any part of the spreader at any time. Do not use PTO guard as a step.

Do not step over the power take-off shaft. Stay clear of the PTO at all times.

Keep PTO shaft telescoping tube shields turning freely. Keep PTO master shield on tractor. Replace shields
missing or damaged.

Match the right tractor PTO spline and speed with the PTO driveshaft provided with the implement. This will assure
proper geometry and operating speed. Never operate 540 RPM implements at 1000 RPM. Never operate 1000
RPM implements at 540 RPM. Never use a spline adapter. Use of adaptors will void warranty due to damage
caused to the tractor PTO, PTO driveshaft or implement.

Use only properly rated tires.

Do not tow at speeds in excess of 20 MPH when transporting this spreader. Never exceed a safe travel speed.

Observe all applicable traffic laws when transporting on public roadways (where legal to do so). Check local laws
for all highway lighting and marking requirements.

Always install a SMV emblem on this spreader for transporting on roadways and keep the emblem clean and bright.

When towing the spreader on public roads a safety chain of sufficient strength to support, along the line of
travel, the gross weight of the spreader must be used (See Maximum Load Weight Chart in the Transporting
Section). The safety chain should be attached per diagram in the Transporting Section.

STUDY THE ABOVE SAFETY RULES

FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

5. PRE-OPERATION

WARNING:

PARTICULAR ATTENTION TO THE “SAFETY PRECAUTION” AND “SAFETY FIRST” PAGES. READ ALL
SAFETY MESSAGES HIGHLIGHTED BY “SAFETY ALERT SYMBOLS” THROUGHOUT THE MANUAL.

WARNING

FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

5.1. SHUTTING OFF AND LOCKING OUT POWER

WARNING

OR SERVICING THIS SPREADER. FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY
OR DEATH.

Whenever adjusting, cleaning, lubricating or otherwise servicing this spreader, you must shutoff and lockout
power to the spreader. Because this spreader can be truck mounted or powered by a tractor, methods vary.
On truck mounted units, the connection between the truck and the spreader is permanently installed and not
intended to be disconnected. On trucks, disengage the PTO drive, turn off the engine, set the parking brake,
remove the ignition keys and keep them in your possession to prevent anyone else from accidentally applying
power to the box unexpectedly. For tractors, disconnect the PTO, disconnect and relieve pressure of the
hydraulics, turn off the tractor and set the brakes.

Throughout this manual, when directed to shutoff and lockout power, be familiar with the previously described
procedures for the type of machine you are operating.

BEFORE OPERATING, READ THIS OWNER’S MANUAL COMPLETELY. PAY

: DO NOT OPERATE WITHOUT ALL SHIELDS, GUARDS AND COVERS INSTALLED.

: SHUTOFF AND LOCKOUT POWER BEFORE CLEANING, ADJUSTING, LUBRICATING

5.2. TRACTOR SETUP

IMPORTANT: NEVER OPERATE PTO ABOVE ITS NORMAL 1000 RPM RATING. TRACTOR'S PTO MUST
MATCH IMPLEMENT PTO.

This spreader must be operated with a 1000 RPM PTO. No
PTO adapter may be used to alter speed or geometry. The
hitch of the spreader is designed for a standard tractor
drawbar. Adjust the drawbar at 15 to 22 inches above the
ground. Extend or shorten the drawbar so horizontal distance
from end of tractor PTO shaft to center of the hitch pin hole is
20” (1 3/4-20), 16” (1 3/8-21). Secure the drawbar so that the
hitch pin hole is located directly below the PTO drive line. See
FIGURE 1 for location of standard measurements.

An improperly located hitch point may cause damage to the
universal joints of the PTO drive shaft. Conforming to the
standard 16" or 20” drawbar & PTO relationship will ensure
that the PTO drive shaft will not become over-extended.

WITH INITIAL HOOK-UP TO YOUR NEW MEYER
SPREADER TEST PTO TRAVEL BY TURNING EQUIPMENT
IN BOTH DIRECTIONS OBSERVING THE MINIMUM AND
MAXIMUM TRAVEL DIMENSIONS AS SHOWN, FIGURE 2.

WARNING

FORCE TO CAUSE INJURY. KEEP ALL HOSES AND CONNECTIONS IN GOOD SERVICEABLE
CONDITION. FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

Whenever working on any part of the hydraulics, safely relieve hydraulic pressure before starting.

: HYDRAULIC FLUID ESCAPING UNDER PRESSURE CAN HAVE SUFFICIENT

5.4. HITCHING TO TRACTOR

Do not allow anyone to stand between the tongue or hitch and the tractor when backing up to the spreader.
Fasten the spreader hitch to the tractor drawbar with a hitch pin that cannot bounce out. Use a 1-5/16” to 1-3/8”
diameter hitch pin.

Remove the weight from the jack (jack is not to be used when spreader is loaded). Remove the jack from
mount tube and move to the transport storage tube on the front of the spreader drive enclosure. Store in a
horizontal position.

Before operation and after hitching the tractor to the spreader, connect the PTO drive shaft to the tractor. Slide
the spring loaded locking collar onto the PTO yoke rearward, and then slide the yoke onto the tractor PTO shaft.

Model 8720 / 8865 -12-

Release the spring loaded collar. Be sure the pins fall into the groove of the tractor PTO shaft and that the collar
snaps forward into the locked position.

NOTICE

Route hydraulic hoses through the hose support
rod which is mounted to the hitch frame, Figure 3.
Connect the hydraulic hoses for the flow control
rear gate to the tractor’s double acting valve
hydraulic system. Move the tractor hydraulic
controls to observe proper flow gate operation. If
the controls operate the gate in opposite
directions to what you expect, reverse the
hydraulic hose connections at the tractor.

5.5.1. UNDERSTANDING THE PTO CUT-OUT CLUTCH

The Meyer 8720/8865 Industrial Series Spreader is equipped with a cutout type clutch on the implement half
of the PTO driveline. The clutch is designed to limit the amount of torque transferred to the machine through
the driveline. If excessive torque is developed the clutch will disengage. A loud ratcheting sound will be
heard and the transfer of power to the machine will be disrupted. To re-engage the machine, simply shut
down the PTO and allow the driveline to come to a stop. The PTO can then be re-engaged to restart the
spreader. The cutout clutch will either re-engage upon shut down of the PTO or just before it comes to a
complete stop.

The cutout clutch will disengage if start up is done in an abrupt or reckless manner. It also will disengage
from foreign materials entering the spinner area of the spreader. It may also be possible to disengage the
clutch by overloading or flooding the spinners with free flowing or liquid manure. If PTO clutch fails to re­engage it will be necessary to remove the foreign object from the spreader before restarting. THERE IS NO

FIELD ADJUSTMENT ON THE CUTOUT CLUTCH.

Model 8720 / 8865 -13-

5.5.2. PTO, ATTACHMENT OF

The cutout clutch end of the PTO driveline must always be attached to the implement. The PTO driveline is
equipped with a 1 3/8-6 spline on the implement half for attaching to the spreader. Remove the M17­hexagon bolt from the splined hub and slide the PTO onto the implement splined input shaft. Install the
hexagon bolt through the hub being sure the bolt is falling into the groove on the splined shaft. Torque tight
using a metric size M17 6-point socket and torque down to 75 ft. lbs. A M17 6-POINT METRIC SOCKET

MUST BE USED AS ROUNDING OF HEXAGON BOLT AND INACCURACY OF TORQUE SETTINGS
COULD OCCUR.

If removal of the M-17 hexagon bolt is necessary, use the same M-17 6-point socket and loosen bolt ½ turn.
Insert a ¼” drift punch in the hole on the opposite side of the hexagon bolt and tap to loosen the seated
portion of the bolt from the splined hub. Loosen in ½ turn increments and tapping to loosen. After bolt seat
has been released, remove the bolt. If bolt is not unseated, damage to the hexagon bolt will occur.

Attach the shield safety chain to a suitable area on the spreader, preferably to the implement PTO steel
shield.

IMPORTANT: THIS MACHINE IS NOT INTENDED TO BE A BALE GRINDER, HAY CHOPPER OR
BEDDING MACHINE. LONG HAY OR STRAW MUST CONTAIN MANURE IN ORDER TO BE SPREAD.
FAILURE TO COMPLY MAY DAMAGE THE DRIVETRAIN AND VOID THE WARRANTY.

NOTICE: TO PREVENT DAMAGE TO AUGERS, SPINNERS, AND DRIVE LINES, FOREIGN OBJECTS
(STONES, CONCRETE, TIMBER, METAL OR LARGE FROZEN CHUNKS OF MANURE) SHOULD NEVER
BE LOADED INTO THE SPREADER.

Before loading, especially in freezing weather, make sure the augers and spinners are free to rotate and the
flow control rear gate moves freely up and down.

Check and be sure that the flow control rear gate is completely closed before loading.

When the spreader is parked for loading, shift the tractor to neutral or park and set the brakes. The moisture
content of the manure will determine how full the spreader can be loaded so that no manure spills out.

You will probably be able to load solid manure at least level with the top of the box while semi-liquid and liquid
manure will have to be less than full in the spreader box. It is unlawful to allow manure to splash or leak onto
public roads.

A liquid manure kit is available for installation around the top of the box on your spreader which will aid in the
containment of liquids.

DANGER

ROTATING SPINNERS BEFORE APPLYING POWER. FAILURE TO HEED MAY RESULT IN SERIOUS
PERSONAL INJURY OR DEATH.

When you are ready to begin spreading application on the field, open the hydraulic flow control rear gate and
slowly engage the tractor PTO clutch. This can be done while traveling forward to avoid a heavier application of
liquid manure at the edge of the field than desired.

For liquid and semi-liquid manure, the application rate can be
controlled by the amount the flow control rear gate is opened.
The gate indicator on the front of the box will provide a ready
reference for the amount of opening. For solid manure (dry,
pen-packed or manure containing long straw or hay) the flow
control rear gate MUST be completely open since this
material is not free flowing.

The rear spinners have been designed and tested to provide
the best spread pattern for most liquids and semi solid
manure. However, the pattern will vary for each specific
condition. The factors that contribute most to differing
patterns will be moisture content and the amount and length
of bedding material. For most typical conditions, the spread
pattern should be uniform and about 15 ft. wide. When this is
the case, plan your spreading patterns so you do not have to travel over previously spread manure which will be
slippery, resulting in poor traction. Traction on wet grass is also poor. When the resulting pattern may require
that you overlap during spreading, use precautions on slopes and hills where you could experience a loss of
traction by traveling over ground with previously spread manure.

NOTE: Further control of the application rate is possible by the relationship of tractor engine speed to ground
speed (transmission gear selection). For optimum, trouble-free performance it is recommended to operate at or
near engine PTO speed.

When the spreader is empty, idle the tractor and stop the PTO. Close the flow control rear gate.

NOTE: Failure to idle the tractor before disengaging the PTO will
cause roller chain over-running and damage to the chain tighteners.

NOTE: Maximum life of the PTO shaft universal joints will result if
you stop the PTO before making turns at the end of the field.

Allow spreader to completely empty last of manure contents, shutoff and lockout power and allow all
movement to stop before attempting to clean the spreader.

Scrape clean any remaining manure from inside the rear of spreader. Clean all manure from ends of augers,
flow control rear gate and spinners.

Make certain that all personnel are clear of the spreader and the rotating spinners before slowly engaging
the PTO. Operate the spreader several minutes to clean manure scrapings and to allow any remaining
manure and the spreader to freeze dry. Hydraulically run the flow control rear gate up and down to clean
gate slide guides. Park spreader with flow control rear gate approximately halfway open.

Before loading in freezing weather, make sure augers and spinners are free to rotate, and the flow control
rear gate moves freely up and down.

7.1. FRONT DRIVE ROLLER CHAINS

There are six roller chain drives located at the front of the spreader. Regularly check that all tensioning springs
are in serviceable condition for automatic roller chain tightening. Manually adjust spring tensioners (as needed)
by turning double locknuts on all tensioning bolt/idler assemblies. Proper roller chain tension is when 1/4" to 1/2"
deflection occurs on the slack side of the chain. Regularly re-check all roller chain tensions. Keep all roller
chains tight at all times! For clarity purposes, the following illustrations detail each roller chain reduction
separately.

NOTE: The side bars of the roller chains will wear into the idler nylon rollers up to the rollers of the roller chain
forming grooves. These grooves will serve as a guide when the roller chain loosens due to normal use. From
this point on, after tightening, the idler nylon rollers should run for hundreds of hours without any noticeable
wear.

The first chain drive (PTO input shaft to the large RH
top sprocket, Figure 6) is automatically tensioned by a
spring loaded idler nylon roller. The extension spring
should extend 2” from its neutral 5” total length.

Manual adjustment for the automatic tensioning idler,
nylon roller assembly is located at the left rear of the
spreader’s front bearing mounting plate.

total length.

Manual adjustment for the automatic tensioning idler,
nylon roller assembly is located at the left rear of the
spreader’s front bearing mounting plate.

The third chain drive is automatically tensioned by a
spring-loaded nylon idler roller. The compression spring
should be compressed to 4.5" in length. See Figure 8.

To increase tension on the automatic tightener, tighten
the adjuster bolt located at the left side of the spreader.

7.2. SPINNER MATERIAL GUIDES

Regularly inspect and adjust two spinner material
guides located at both the left rear and right rear of
the spreader. Create a 1/8-3/8” clearance between
material guides and spinner teeth (Figure 12).
Maintain the recommended clearances for
maximum spreading pattern. Adjust to prevent
excessive manure build-up on material guide inner
surfaces. Adjust to prevent manure chunks or
foreign object lodging between material guides and
spinner teeth.

NOTE: Excessive lodging can cause premature
spinner tooth wear, “bent-over” or even breakage.

The side shaft chain drive (PTO input shaft to the side line
shaft drive sprocket, Figure 11) is automatically tensioned
by a spring-loaded idler nylon roller. The extension spring
should extend 2" from its neutral 5" total length.

Manual adjustment for the automatic tensioning idler,
nylon roller assembly is located at the right rear of the
spreader’s front bearing mounting plate.

FIGURE 12. MATERIAL GUIDE CLEARANCE

7.3. SHEAR ARM MATERIAL GUIDE

Adjustment for the 1/8-3/8” clearance of each material guide to spinner tooth is made by loosening the jam nut
on the linkage arm and turning the linkage arm to either move the guide in closer or out farther from the spinner
teeth. After adjustment has been made for the 1/8”-3/8” clearance, retighten the jam nut to hold the material
guide in place. Once recommended clearance is obtained turn spinners over by hand in the direction by which
the spreader would turn to check clearance. Do not turn in the opposite direction as front chain tightener
damage could occur. If foreign objects enter the spinner area the front pivot bolt on the shear arm is designed to
shear. The extension spring will pull the material guide away from the spinner until the shear bolt is replaced.
The 1/2-13 x 3 1/2” grade 5 replacement machine bolts are stored under the rear shield. For replacement install
with 1/2” flat washer on top of shear eye and on bottom of block and tighten nylon locknut firmly.

FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

The automatic chain oiler attachment gives a squirt of clean oil to all roller chains every time that the spreaders
rear gate, hydraulic cylinder is activated. In this way, the spreaders roller chains get oiled in direct proportion to
the number of hydraulic cylinder cycles of the rear gate. This assures adequate lubrication.

New 30 weight oil, which is placed in the reservoir tank mounted on the spreader, is all that is needed to
properly lubricate all roller chains and sprockets. The automatic chain oiler does not use any oil from the
tractor’s hydraulic system. The hydraulic hose connected to the bottom of the oiler pump only serves to power
the piston in the pump every time that the spreader’s rear gate is opened.

Should the oil reservoir tank run dry, pour about a 1/2 cup of
clean 30 weight oil into the tank. Allow time for the oil to run
down into the oiler pump slowly and allow air to escape. After
thirty minutes to one hour has passed, finish filling the reservoir
tank. Make sure that all fittings and brackets are tight when
finished filling the tank.

While running the tractors hydraulics only, open and close the
spreaders rear gate several times. This will cycle the hydraulic
cylinder leading to the oiler pump. Keep cycling until oil can be
seen in all of the oil lines leading to the oiler brushes. (If you
experience problems priming the oiler pump, you may need to
bleed air out of the hydraulic hose where it is connected to the
pump. Crack the fitting until oil comes out, and then re-tighten.)
The hydraulic cylinder that the oiler pump is tied into is double
acting and must reach 300 PSI of pressure to actuate the pump.

When replacing oiler brushes into brush holders, use regular 1/2"-20 nuts.
Tighten nut finger tight initially as some adjustment may be needed later. For
best results, place brush holders over top of roller chains and directly on top of
sprockets. Adjust brush holders so oiler brushes are pushed down into the
roller chain approximately 1/2". Carefully tighten up the 1/2"-20 nuts on the
oiler brushes. DO NOT over tighten as damage to the brush will occur. The
plastic threads of the oiler brush will crack and then break off from the brush
body.

IMPORTANT! The 5/32" oil line
tubing can only be removed from
an oiler brush by pushing in on
the red plastic ring and pulling the
tubing out while holding the ring
down.

The oiler pump is set at the factory to
deliver the maximum amount of oil
per cycle. If less oil is desired, loosen

the jam nut on the bottom of the
pump and screw in the adjusting shaft 1/4" or approximately 5 turns.
It is not recommended to screw the shaft into the bottom of the oiler
pump more than 15 turns as this may not allow for proper lubrication
of the roller chains.

IMPORTANT! Always use new 30 weight oil. In cold weather,
use a SAE 10 or a mixture of two parts of 30 weight oil to one
part diesel fuel.

Before storing this spreader for an extended period of time perform the following:

Allow the spreader to completely clean out the last load. Thoroughly hose off all manure from the outside of the
spreader and the inside of the box, particularly getting the flow control rear gate mechanism clean. The wash water
can be drained into your manure storage pit, or if the gate is left closed, the water can be spread on the field. After
cleaning, completely lubricate the entire spreader to exclude moisture from bearings and to prevent condensation
from forming during storage. See “Lubrication” pages, starting on page 22.

Oil the roller chains by running the spreader at idle speed while opening the rear gate to activate the automatic oiler
system. It is also a good time to inspect all adjustments and check for parts that need repair or replacement.
Performing these tasks now will guarantee that the spreader is ready for use at the beginning of the next season.

Whenever adjusting, cleaning, lubricating or otherwise servicing this spreader, you must shutoff and lockout
power to the spreader. Because this spreader can be truck mounted or powered by a tractor, methods vary.
On truck mounted units, the connection between the truck and the spreader is permanently installed and not
intended to be disconnected. On trucks, disengage the PTO drive, turn off the engine, set the parking brake,
remove the ignition keys and keep them in your possession to prevent anyone else from accidentally applying
power to the box unexpectedly. For tractors, disconnect the PTO, disconnect and relieve pressure of the
hydraulics, turn off the tractor and set the brakes.

At times, parts on this equipment will become worn or damaged. Performing repairs on this equipment can
