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 20 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
necessary 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.

WARNING: NEVER OPERATE PTO ABOVE

ITS NORMAL 540/1000 RPM RATING. NEVER
CONNECT SPREADER PTO SHAFT TO A 1000
RPM TRACTOR PTO, UNLESS THE SPREADER IS
EQUIPPED WITH A 1000 RPM OPTIONAL KIT OR
IS FACTORY BUILT FOR 1000 RPM. TRACTOR PTO
MUST MATCH IMPLEMENT PTO. FAILURE TO
HEED MAY RESULT IN SPREADER DAMAGE OR
SERIOUS PERSONAL INJURY.

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 while
making turns at the end of the field.

CAUTION: DO NOT EXCEED THE

MAXIMUM 80° TURNING ANGLE ON THE
CONSTANT VELOCITY PTO DRIVE LINE.
EXCEEDING THE TURNING ANGLE WILL
DAMAGE THE CONSTANT VELOCITY “CENTER
HOUSING” AND WILL EXERT EXCESSIVE
PRESSURES ON THE PTO INPUT CENTER SHAFT
AND RELATED BEARINGS.

SHEAR SPROCKET INSTRUCTIONS

(7500 Models - Standard, 7400 Models - Optional
Prior to SV117400201)

The Meyer Spreader you have received has been
equipped with a shear sprocket design on the main
auger drive sprockets. The augers are being driven by
two Allen head grade 8 shear bolts on each drive
sprocket. The design is such that if the bolts are
sheared another set of holes to install new shear bolt
will always be accessible without turning over the
machine.

DANGER: AT NO TIME SHOULD

INSTALLATION BE DONE WITH ANYONE ON THE
TRACTOR. SHUT THE TRACTOR OFF, REMOVE
THE KEY AND DISCONNECT THE DRIVE LINE
BEFORE DOING ANY SERVICE ON THIS
MACHINE. SERIOUS INJURY OR DEATH MAY
OCCUR IF SAFETY IS NOT FOLLOWED.

Prior to Serial Number SV117400402 and
SV127500243 & Later, the shear plate sprocket is set
up with the standard drive bolts being 1/2"-20 (see
figure 5 on page 19). If the 1/2”-20 bolts do shear,
replace with the same 1/2”-20 diameter bolts after the
obstruction has been removed. Install the new bolts in
the proper way as to drive off of the head of the bolt,
not the nut. Shear or sprocket failure will occur if
assembled incorrectly! An extra set of holes for 9/16”-
18 drive bolts are located on the sprocket if additional
shear strength is needed due to shear bolt failure from
extra tough material that is being spread. The two
different size holes available (1/2”-20 & 9/16”-18) are
close in size.

Be sure to install the proper size bolt

into the correct size hole.

CHANGING TO THE 9/

16”-18 BOLTS PROVIDES LESS PROTECTION
