SECTION 2: ATTACHING THE SPREADER
TO THE TRACTOR
Connecting the Spreader to the Tractor
1. Back the tractor within a few inches of the spreader hitch.
2. Use the jack provided with your spreader to adjust the height of the spreader hitch so the tractor
drawbar matches the height of the spreader hitch.
3. Back the tractor into the hitch until the holes of the spreader hitch and tractor drawbar line up.
4. Fasten the spreader hitch to the drawbar 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.
5. Remove the weight from the jack by lowering the spreader hitch on the drawbar.
6. Swing the jack to its horizontal position and lock it in position to provide maximum ground clearance.
Adjusting the Spreader Operating Lever
Following hook-up of the spreader to the tractor, check the length of thespreader operating lever for two
criticaldistances:
• The length of the operating lever should allow for comfortable access by the operator (while
seated on the tractor).
• The length should also allow for a minimum five (5) inch clearance from the rear of the tractor at
all times, especially when the tractor and spreader are operating on uneven ground.
1. Position the tractor and spreader on level ground.
2. While seated on thetractor, determineif thelever is withincomfortable reachingdistance.
3. Raise and lower the lever to determine if the lever would possibly come in contact with the rear of the
tractor if the tractor and spreader were on uneven ground (e.g. in a gulley).
NOTE: The lever must maintain a distance of at least five (5) inches from the rear of the tractor at all
times.
4. If it is determined that the lever length needs to be adjusted to accommodate better operator access
and/or to maintain a safe operating distance from the rear of the tractor, the lever may be disassembled
andits length adjusted as follows:
• Refer to the Front Drive Assembly Parts Drawing in Appendix A at the back of this manual
for a detailed view of the spreader operating lever and its component parts.
• Remove the two (2) bolts that hold the lever components together.
• Re-position the lever components by aligning the holes to shorten or lengthen the lever as
needed.
• Re-install the two (2) bolts on the lever and tighten securely.
5. Verify that you can comfortably reach the lever while seated on the tractor, then raise and lower the
lever to verify the distance from the rear of the tractor. Re-adjust the length of the lever as necessary.

SECTION 3: OPERATION
Understanding Spreader Operation
Proper and safe operation of the Millcreek 57G/77G 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
(i.e. as an operator sits on the tractor seat, the right side of the spreader is over his/her right shoulder, the left
side of the spreader is over his/her left shoulder).
The following operating components are included with the Standard Model 57G/77G spreaders:
• The adjustable, feather-touch Spreader Operating Lever is used to control the operation of the
spreader; it engages the chain that drives both the beaters and the apron chain to push the manure
toward the back of the spreader for disbursement. Pushing DOWN on the operating lever engages
operation (ON), while pulling UP disengages operation (OFF).
• The swing-away jack facilitates hook-up of the spreader to the tractor.
• The T-rod apron chain provides reliable material movement in the spreader load after load.
Optional operating components (ordered separately) for the Model 57G/77G include:
• The manual endgate helps to contain loads between spreading and also shields the operator during
spreading.
• Thefines pan aidsin distributing fine materials (e.g. compost) evenly.
• The safety chain, which is strongly recommended for use when the spreader is transported on a
publicroadway.
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.

Operator's Manual: Millcreek 57G & 77G Ground Drive Spreaders

Operating the Spreader
WARNING! 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: 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 6.0 miles per hour (i.e. similar to a very
brisk walking pace) can cause excessive wear or damage to the equipment.
ATTENTION: Verify that the spreader operating lever has been set to the proper length for easy
operator access and minimum five (5) inch clearance from the rear of the tractor chassis. Refer to Section 2 for
adjustment instructions, if needed. Failure to properly adjust the lever may result in damage to the spreader
duringoperation.
1. Ensure that the spreader (and tractor) are not in motion (in a stopped position).
2. If you have a spreader with the endgate option, lift the endgate.
3. To engage the apron chain for spreading action, push DOWN on the operating lever.
4. Ensure that you are reaching the optimal operating speed for spreading (at least 3.0 mph, but not
more than 6.0 mph). Remember that this optimal speed is similar to a comfortable walking pace.
5. When the spreader box is completely unloaded, disengage the apron chain drive by pulling UP the
operatinglever.
6. Refer to Section 4 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 4 in this manual for the proper torque specifications.

SECTION 4: 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 you 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
outdoorswith manure in it) will acceleraterusting of thesteel.
• Check the spreader each time it is used for loose, bent, broken or missing parts.
ATTENTION: Duringoperation,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
specificationsfor tightening the hitch hardware;failureto tighten all hitch hardware securelymay
resultin equipment damage.
Hardware Torque Specification
1/2" 60 ft. lbs.
3/8" 25 ft. lbs.
5/16" 15 ft. lbs.
• Check that implement tires have adequate air pressure (30 psi). Always use ag-traction
implement tires on the drive wheels. Wheel bolts should be torqued to 75 to 80 ft. lbs.
• Inspectthe safety chain regularly to checkthe condition of thelinks and locking/hooking
mechanisms; replace the chain as soon as weakness/breakage is noted.
• Apply chain lube once a month (or as needed) to the drive chains (shown in Figure 4B);
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
commonspray lube for chains.

Guidelines for Regular Maintenance (continued)
Figure 4A - Adjusting the Floor Apron Chain for Proper Tension
• Periodically check the floor apron chain for proper tension/tightness (refer to Figure 4A).
Procedure for checking/adjusting the floor apron chain:
a) Check the distance between the apron chain and the bottom of the side sheet at the apron's
lowest point (just behind the wheels). If the distance is more than 6-1/2 inches, the
chain must be tightened.
NOTE: The recommended floor apron chain tension is achieved when the apron's
lowest point is 4-1/2 to 5 inches below the frame (behind the tire).
b) Use a 9/16" wrench to tighten the adjustment nut on the lower left/right front of the spreader
box as shown in Figure 4A. Observe the chain positioning with respect to the floor/apron.
Make sure that the chains on each side of the apron are equally taut.

Adjusting the Ratchet Drive Chain
NOTE: The ratchet drive chain is factory-set for the proper operating tension and should not require
adjustment. The following instructions are provided for reference only, in rare cases where re-adjustment or
replacementmay become necessary.
Refer to Figure 4B on the previous page for an illustration of the ratchet drive chain and related components.
The chain should be snug, but not too tight. If the chain is too tight, it may cause excessive wear on the bushings
inthe crank arm sprocket (resulting in prematurefailure).
•To check the ratchet drive chain: push on the middle of the span (either top or bottom)
with one finger (about 20 lbs. pressure) -- the chain should deflect about 3/8 to 1/2 inch. A
straight-edgeruler may be helpful in verifying the proper setting.
•To adjust the ratchet drive chain (refer to Figure 4B): adjust the bracket position by
loosening the two (2) 1/2" bracket bolts and sliding the bracket forward or backward (to
tighten or loosen) as shown. Following adjustment of the bracket position, verify that the
drive chain is set to the proper tension as specified above.
NOTE: The longer ground drive chain is spring tensioned and is NOT adjustable.
