SECTION 2: OPERATION
Understanding Spreader Operation
Proper and safe operation of the Millcreek 27G/37G Spreader requires: (1) being familiar with the spreader's
operating components and (2) heeding all safety precautions as stated in this manual.
The Spreader Operating Components
By definition, the left and right sides of the spreader are determined while sitting on the tractor seat. The
following operating components are included with the Standard Model 27/37 spreaders:
• The dollywheel/jack allows easy movement of the spreader around the stable or barn; also adjusts
the height of the spreader to facilitate hook-up to the spreader towing vehicle.
• The endgate helps to contain loads between spreading and also shields the operator during
spreading.
• The lefthand spreader lever engages the floor apron chain which moves the manure to the
rear of the spreader and into the beater.
• The righthand spreader lever engages the chain that drives the beater and spreads the
manure.
Connecting the Spreader to the Towing Vehicle
For operation in the field, the Millcreek Model 27/37 spreaders can be towed by a number of vehicles--garden
tractor, ATV, or utility vehicle. Please adhere to the following procedure for connecting the spreader to your
towing vehicle. Attaching the spreader to the towing vehicle as instructed is necessary for safe and
proper operation of the equipment.
1.
2.
3.
Back the towing vehicle within a few inches of the spreader hitch.
Refer to Figure 2A. Determine the spreader hitch position required to allow the spreader to remain
parallel to the ground with relation to the towing vehicle.
NOTE: As shown in Figure 2A, the adjustable hitch on the front of the spreader may be positioned in
a number of ways, by sliding up/down or inverting, to achieve a higher or lower positioning of the
spreader hitch.
Re-position the adjustable hitch as required and tighten the two (2) 1/2" bolts and lock nuts securely.
Figure 2A - Adjusting the Hitch Position
2-1
Operator's Manual: Millcreek 27G & 37G Spreaders
Attaching the Spreader to the Towing Vehicle (continued)
4.
Refer to Figure 2B. Adjust the overall height of the spreader/hitch with the dollywheel/jack so the
height of the spreader hitch matches the height of the tractor drawbar or vehicle hitch point (as
applicable).
NOTE: The dollywheel/jack is held in its upright position with a spring-loaded pin. To release the jack
to move it into its operational position, simply pull the pin outward and swing the jack down.
Figure 2B - Using the Dollywheel/Jack
5.
6.
7.
8.
Back the towing vehicle into the hitch until the holes of the spreader hitch line up with the vehicle hitch
point.
Fasten the spreader hitch to the vehicle drawbar/hitch point with a hitch pin that fits securely (i.e. so that
it will not come out during spreader operation) and lock in place with the safety clip.
WARNING: Damage to the spreader or other vehicle, as well as injury to the operator,
may occur if a properly-sized hitch pin is not installed as recommended. Note that the installation of the
safety clip to hold the hitch pin in place is also required for safe spreader operation.
Remove the weight from the dollywheel/jack by lowering the spreader hitch on the vehicle drawbar/
hitch point.
To provide adequate ground clearance for operation, swing the dollywheel/jack up into its resting
position (i.e. pull the spring-loaded pin out to release the jack and swing the jack upward, then allow
the pin to re-engage to hold the jack in its upward position.)
Guidelines for Loading the Spreader for Operation
•
•
•
Millcreek recommends that you load the spreader from the front toward the back to facilitate
easier unloading.
ATTENTION: NEVER store manure in the spreader between unloading times during critical cold
weather months when a frozen load could result in severe equipment damage (i.e. torn floor apron
chain).
DO NOT store wet manure in the spreader (or keep the spreader outdoors with manure in it)-doing so will accelerate rusting of the steel.
2-2
Operator's Manual: Millcreek 27G & 37G Spreaders
Operating the Spreader
Before proceeding with operation of the spreader, review all safety statements
as provided in Section 1 of this manual.
WARNING: To prevent serious personal injury, ensure that ALL safety shields are in place on the
spreader before starting operation. NEVER operate the spreader without ALL safety shields in place.
ATTENTION / CAUTION: In order to obtain proper, aggressive spreading action, the spreader ground
speed must reach a minimum of 3.0 miles per hour--the equivalent of a comfortable walking pace.
(Note that the wheels drive the beater action.) However, spreading at speeds over 5.0 miles per hour (i.e.
similar to a very brisk walking pace) can cause excessive wear or damage to the equipment.
1.
2.
3.
4.
5.
6.
7.
8.
9.
Ensure that the spreader (and towing vehicle) are in a stopped position (i.e. NOT in motion).
Lift the manual endgate.
Engage the right lever to start the beater.
Begin moving forward, and engage the left lever, which starts the action of the apron floor chain
(moving the material towards the rear of the spreader).
Ensure that you are reaching the optimal operating speed for spreading (at least 3.0 mph, but not
more than 5.0 mph). Remember that this optimal speed is similar to a comfortable walking pace.
When the spreader is almost empty and there is very little manure pushing against the beater,
disengage the right spreader lever (which controls the beater rotation).
Allow the apron chain to run the remaining manure out the back of the spreader.
When completely unloaded, disengage the left spreader lever to stop the action of the apron
chain.
Refer to Section 3 in this manual for maintenance to be performed following operation of the spreader.
IMPORTANT! After a few hours of initial operation, watch and listen for any loose components.
Be aware that it may be necessary to re-tighten hitch hardware and/or wheel bolts; please refer to
Section 3 in this manual for the proper torque specifications.

SECTION 3: MAINTENANCE & ADJUSTMENT
Guidelines for Regular Maintenance
WARNING: All shields must be replaced after maintenance or adjustment procedures are
performed. Failure to do so could result in serious personal injury or death.
Performing regular maintenance on your Millcreek Spreader will help ensure optimal performance. Please
follow these guidelines for maintaining your spreader:
•
Clean the spreader once a week and before storing the unit for an extended period of time.
ATTENTION: NEVER store manure in the spreader between unloading times during
critical cold weather months when a frozen load could result in severe equipment damage
(i.e. torn floor apron chain). Storing wet manure in the spreader (or keeping the spreader
outdoors with manure in it) will accelerate rusting of the steel.
•
Check the spreader each time it is used for loose, bent, broken or missing parts.
ATTENTION: During operation, listen for abnormal sounds which might indicate loose
parts or other equipment damage. Correct any parts problems immediately; expanded parts
views of all spreader assemblies are provided in the Appendixes at the back of this manual.
ATTENTION: For safe and proper operation of the spreader, adhere to the following
specifications for tightening the HITCH HARDWARE; failure to tighten all hitch hardware
securely may result in equipment damage.

*Note that these torque specifications apply to the hitch members fastened to the
spreader box, NOT to the adjustable hitch prong bracket at the front of the hitch.
•
Check that implement tires have adequate air pressure (28 psi). Always use ag-traction
implement tires on the drive wheels. Wheel bolts should be torqued to 60 ft. lbs.
•
Apply chain lube once a month (or as needed) to the drive chains (shown in Figure 4C);
use vegetable oil or a common spray lube for chains.
•
Apply chain lube once a month (or as needed) to the floor apron chain; use vegetable oil or a
common spray lube for chains.
3-1
Operator's Manual: Millcreek 27G & 37G Spreaders
Guidelines for Regular Maintenance (continued)
•
Periodically check the floor apron chain for tension/tightness (refer to Figure 4A).
Procedure for checking/adjusting the floor apron chain:
a) Pull up on the center slat of the floor apron chain.
b) If you can lift it higher than 5 inches, the chain is too loose.
c) If you can lift it no higher than 3 inches, the chain is too tight.
d) If the chain needs adjustment, use a 1/2" wrench to loosen the two side nuts on each
side of the spreader box as shown in Figure 4A. Turn the front nut clockwise or
counterclockwise until correct tension/tightness is achieved. Repeat for the other
side. Make sure that the chains on each side of the apron are equally taut.
e) Re-tighten the side nuts.

Procedures for Spreader Adjustment
Problems with spreader operation may indicate that certain adjustments are required to restore proper
functioning. The following procedures address common problems which may be encountered in
spreader operation.
Adjusting the Rear Pawl
If the floor apron chain is not moving, the most common cause is improper brake (rear) pawl adjustment.
(by jacking up the lefthand drive wheel and turning the wheel by hand, you will be able to observe the
brake pawl engagement in the sprocket teeth.)
1.
2.
3.
4.
5.
6.
Refer to Figure 4B.
Remove the shield covering the brake pawl assembly by removing the two (2) bolts, washers,
and nuts holding it in place.
Loosen the nut behind the brake pawl using a 9/16" wrench.
With the roller positioned at the highest point on the star cam, tap the brake pawl up or down as
necessary to attain a 1/16" to 1/8" clearance between the brake pawl and the sprocket tooth (see
close-up detail in Figure 4B).
After the desired adjustment is achieved, re-tighten the rear nut.
Replace the safety shield.
