OPERATIONGENERAL INFORMATION

IN THE FOLLOWING INSTRUCTIONS "LEFT"AND "RIGHT" ARE DETERMINED FROM APOSITION FACING THE DIRECTION OF TRAVEL

The Model 355 grinder-mixer is intended to

be basically a grain processing grinder-mixer.However, roughage can be blended with grainin reasonable quantities.

TRACTOR HITCH

The hitch of the Grinder-Mixer is designedfor standard tractor hitch. Adjust the drawbarso that it is 13 to 17 inches above the ground.EXTEND OR SHORTEN IT SO THAT THE HORI-ZONTAL DISTANCE FROM THE END OF THETRACTOR POWER TAKE OFF SHAFT TO THECENTER OF THE HITCH PIN HOLE IS 14 INCHES,AS SHOWN IN FIGURE 1. Use an adapter plate,

if necessary, to secure the proper distance. ANIMPROPERLY LOCATED HITCH POINT MAYCAUSE DAMAGE TO THE UNIVERSAL JOINTSOF THE POWER TAKE OFF.

Secure the drawbar so that the hitch pin holeis directly below the power drive line.

14 FOR 540 R.PM.

ATTACHING TO THE TRACTOR

1. Fasten the Grinder-Mixer hitch to thedrawbar with A HITCH PIN THAT CAN-NOT BOUNCE OUT.

2. Remove the weight fronn the jack, swingit to its horizontal position, and lock it to

provide a maximum ground clearance.

3. Depress the spring loaded pin on theP.T.O. yoke and slide it on the tractor

P.T.O. shaft. Be sure the pin falls in thegroove of the P.T.O. shaft.

HAMMERMILL DRIVE

The hammermill drive is engaged or disen-

gaged as shown in Figure 2 by moving thepin in or out of the drive assembly.

IMPORTANT:

Do not off-set tractor draw bar to align P.T.O.

assembly. Keep draw bar directly beneath the

tractor P.T.O. If tractor draw bar is off-set, the

P.T.O. can bottom and cause damage.

OPERATING SPEED

During the grinding and mixing operation

maintain the standard 540 RPM on the P.T.O.

Use slow P.T.O. speed to stop the P.T.O. whenengaging the unloading auger clutch.

FIGURE 2

LOADING AUGER DRIVE (Mechanical)

During operation the loading auger can beengaged or disengaged by the clutch lever

shown in Figure 3.

The loading auger is held in transport posi-

tion with the transport latch shown in Figure 3.

LOADING AUGER DRIVE (Hydraulic)

The speed of the loading auger can be con-

trolled with the loading auger speed control

valve. The loading auger can be stopped bymoving the lever as indicated in Figure 3A.

IMPORTANT: The loading and unloading au-

gers are driven with orbit nnotors. If the augers

become jammed with material or foreign ob-

jects, the orbit motor will stall. When this oc-

curs, oil no longer is pumped through the entire

hydraulic system but is forced across the pres-

sure relief valve that is factory set at 2000p.s.i. relief pressure.

FIGURE 3

The operator must disengage the power sup-ply immediately after these conditions. The ob-struction or overload must be removed beforeoperation is continued.

Permanent damage from excessive heat couldoccur if both pump and motor were to continueoperation under these conditions.

BE CAREFUL AKEEP HANDS CLEAR OF AUGERS

WHILE MACHINE IS IN OPERATION.

9. Observe the mixing of the feed and the

amount in the tank through the tank win-

dows. NOTE: The tank is filled to capacity

when the material covers the top windowand suddenly drops away.

10. When adding concentrates or special feeds

through the concentrate hopper at the rear

of the unit the grinder mixer should beoperating at 540 R.P.M. See Figure 7. Donot add material through the concentrate

hopper and hammermill at the same time.

n. When the tank is full or the feed mixtureis completely mixed, stop the unit and dis-

engage the hammermill drive.

NOTE: The unloading auger clutch may beengaged or disengaged while the unit is

operating if necessary, but should be doneat slow tractor R.P.M.

12. To unload, release the auger transport latch

and raise the unloading auger to clear the

transport support. Release the outer augerlatch and swing the auger end to couple

with the auger base section. Augers mustalign and engage properly before locking

over center clamp. Lock the auger sections

together and position auger to desired po-

sition. IMPORTANT: Lock the unloading au-

ger brake when unloading. Damage can

occur to the bearing and yoke if the brake

is not locked when operating the unload-

GRINDING HAYTo grind hay with the unit, place the load-

ing auger in transport position, and disengage

the drive. Open the hammermill gate to a wideposition. For best results feed slices 3" to 5"

thick into hammermill. For fine grasses and

slough hay feed thinner slices.

FIGURE 12

GRINDING WITHOUT MIXING

If it is desirable to grind but not mix the feedmaterial, engage the unloading auger drive,

open the tank unloading auger gate and start

grinding. The material will be conveyed to the

bottom of the tank and out through the unload-ing augers without mixing.

When operating in this manner the bevel

gears will need frequent lubrication,

MIXING HIGH MOISTURE, LIGHT WEIGHT, ORBULKY MATERIAL

For best mixing results, always add light-

weight or bulky materials last. Always addhigh moisture corn or grain last.

Excessive amounts of wet material, light

weight material, or bulky material, will causebridging in the mixing tank. Therefore, mix-ing will not be adequate and unloading timewill be very slow.

UNLOADING AUGER DISCHARGE HEIGHTThe lower limit discharge height of the un-

loading auger is controlled by the length of

cable on the winch. The winch contains the

maximum amount of cable that can be usedas it is shipped from the factory. If the cableis lengthened, the unloading auger gears maylock and cause breakage of the unloading auger

clutch or gear box. If it is desirable to lower thedischarge height of the unloading auger, theoptional flexible down spout attachment shouldbe added.

ABE CAREFUL

MAKE SURE THE HAMMERMILL IS

COMPLETELY STOPPED BEFORE

OPENING THE COVER TOCHANGE THE SCREENS

CHANGING HAMMERMILL SCREENS(Be sure Tractor Engine has stopped)

To change the hammermill screen:

1. Open the cover by loosening the over cen-ter clamp.

2. Insert the hook in the screen and pull upand outward as shown in Figure 14.

3. Install the screen by dropping in place andclosing the door.

TO

FIGURE 14

4. Extra screens may be carried in the screenrack and secured as shown in Figure 14.

NOTE: Clean rust preventive fronn screens

before installing them.

TRANSPORTING THE GRINDER-MIXER

When moving the unit with material in the

tank, the mixing auger should be run at a slowspeed.

If the Grinder-Mixer is equipped with a load-

ing auger , the right side of the hopper can befolded.

SCREEN SIZES

The following suggested screen sizes maybe used as a guide for grinding different typesof feed.

1. Dairy cattle:

Ear corn- 1/4-1/2"

Small grains -3/16-5/16"

2. Hogs and poultry:

Shelled corn- 1/8-1/4"

Small grains -3/32-1/4"

3. Beef Cattle:

Ear corn- 1/4-1"

Shelled corn -3/16-1/2"Small grains -3/16-1/2"

NOTE: Do not attempt to grind ear corn

through a screen smaller than %" or hayand straw through a screen larger than %"for satisfactory performance. Grinding high

moisture material could cause grinding andmixing problems.

Always attach the PTO to the tractor or at-

tach it to the PTO carrier as shown in Figure 1 2.

The reflective tape and SMV emblem on therear of the machine should be cleaned regular-

ly when transporting the unit on a highway.

LUBRICATIONUnder normal conditions, the Sperry New

Holland Grinder-Mixer should be greased EV-

ERY EIGHT HOURS OF OPERATION, OR ONCEA MONTH, whichever comes first. It should belubricated more often if operating under ex-

tremely heavy loads or extremely adverse con-

ditions.

The following is a list of points that require

lubrication, with a reference number that iden-

tifies each location on the corresponding de-

tail pictures. A single asterisk in front of the

reference number indicates lube point for me-

chanical drive only. A double asterisk applies to

hydraulic drive only. All other reference num-bers apply to either unit. All points except those

with special notations should be lubricated with

a good grade of grease until grease is forced

out around the bearings. The excess grease

should then be wiped off. Dirt should be wipedfrom the fittings before applying grease.

LOADING AUGER SPEED (Mechanical)

The loading auger operating speed is

changed by reversing the double sprocket for

two faster speeds or interchanging the sprock-

ets on the shafts for two slower speeds. SeeFigure 26.

The four speeds for the loading auger are:

Auger R.P.M.

ADJUSTABLE MIXING TUBEThe adjustable mixing tube section is installed

at the factory in the lowest position. It shouldbe used in the lowest position when grindingfree flowing nnaterials. The adjustable section

can be raised to improve the flow of material

with a high percentage of roughage on theModel 355. To relocate the adjustable section,

loosen the bolts on the section and position in

desired location. The adjustable mixing tubeextension is shown in Figure 30 removed fromthe mixing tank for clarity.

FIGURE 30FIGURE 32

LOADING AUGER BRAKE

The loading auger brake is a positive type

and can be adjusted with the jam nuts shownin Figure 31. For correct tension on the brake,

it requires 10 lb.-pull to pull the lever over cen-

ter.

UNLOADING AUGER BRAKE

The unloading auger brake is a positive type

and can be adjusted with jam nuts as shown in

Figure 32. For correct tension on the brake it

requires 40 lb.-pull to pull the lever over center.

The clamp stop bolt shown in Figure 32should be tightened to keep the clamp tight, but

the unloading auger should pivot easily.

GEAR BOX AND TRANSFERAUGER DRIVE CHAINS

Adjust the drive chains as shown in Figure32A by loosening the idler on the drive chain

and moving it as required so that the chain canbe deflected %" with a 25 lb. force in the cen-ter of the span.

SHEAR BOLT

The gear box is shear bolt protected. If shearbolt breaks, always replace with genuine NewHolland shear bolt after determining the causeof failure. Extra shear bolts may be carried in

the convenient carrier shown in Figure 26. Thegear box shear bolt is shown in Figure 32A.

FIGURE 32 A

LOADING AUGER PRIMARY DRIVE CHAIN

The loading auger primary drive chain is

tightened by means of the idler shown in Fig-

ure 26, and the secondary drive chain is tight-

ened by means of the idler under the cover

at the lower end of the auger. Both chains

should be adjusted to deflect 1" with a 25pound force in the center of the span.

HAMMER MILL DRIVE BELT (Mechanical Drive)

IT IS IMPORTANT THE HAMMER MILL DRIVEBELT BE KEPT TIGHT AND ALIGNED PROPERLYAT ALL TIMES, to prevent damage to the belt.

To adjust the belt do the following:

1. Loosen the gear box drive chain idler,

shown in Figure 32A, and remove the belt

shield.

2. It is important the belt be aligned proper-

ly. Use a straight edge to check the align-

ment of the hammer mill drive and driven

sheaves before tightening the belt. Shouldthe sheaves need aligned. The alignment

can be accomplished by tightening oneor the other of the nuts on the adjusting

bolts shown in Figure 34. Sheaves should

be aligned to within 1/32".

3. To tighten the belt, loosen the bolts at

E, Figure 34. Back off the nuts at A, Figure

34. Tighten the belt by turning the nuts

equally at C and D in a clockwise direc-

tion. After tensioning the belt check the

belt sheaves for proper alignment. Re-

tighten the nuts at A and E, Figure 34.

FIGURE 33

HAMMERMILL DRIVE BELT (Hydraulic Drive)

This procedure should be followed when ad-

justing the hammermill drive belt on hydraulicunits.

1. Loosen the gear box drive chain. Figure

32A.

2. Loosen the two bolts at A, Figure 33.

FIGURE 34

3. It is important the belt be aligned properly.

Use a straight edge to check the alignmentof the hammer mill drive and driven

sheaves before tightening the belt. Shouldthe sheaves need aligned. The alignmenrcan be accomplished by tightening one or

the other of the nuts on the adjusting bolts

shown in Figure 34. Sheaves should bealigned to within 1/32".

To tighten the belt, loosen the bolts at E,

Figure 34, and back off the nuts at A, Fig-

ure 34. Tighten the belt by turning the

nuts equally at C and D in a clockwise di-

rection. After tensioning the belt check the

belt sheaves for proper alignment. Retight-

en the nuts at A, Figure 34.

When properly tightened, the belt will de-

flect W to %" when 50 pounds are ap-

plied at the center of the span of the belt.

For long belt life and proper performanceof the mill, keep the belt properly tightened

at all times.

DO NOT OVERTIGHTEN THE BELT OR DA-MAGE TO THE DRIVE COMPONENTS MAYRESULT.

4. After the belt is properly tensioned, tighten

the two bolts at A, Figure 33.

5. Loosen hose clamp B, Figure 33 and pumpmounting bolts C. Move the hydraulic

pump until all slack is removed from drive

chain and re-tighten the pump mountingbolts at C and tighten hose clamp B.

6. Tighten gear box drive chain shown in Fig-

ure 32A.

REPLACING OR TURNING THE HAMMERMILLHAMMERS

The hammermill hammers are replaceable or

A

can be turned to use four different edges. To

change the hammers or remove them, removethe screen and then remove the pin shown in

Figure 35 through the hole in the hammermill

side sheet. The hammers can then be turned

or new hammers installed as the pin is rein-

stalled through the hammermill plates. It is im-

portant that the hammers and spacers be put

back in the same exact location from which they

were removed, or the rotor may not be bal-

anced and cause serious vibration of the unit

while it is operating. See Figure 36 for ham-mer 'spacer location.

Use new roll pins in the hammer pin.

FIGURE 35

IMPORTANT: WHEN REPLACING HAMMERS,THEY MUST BE REPLACED IN MATCHED SETSOF 36 HAMMERS TO PREVENT VIBRATION OROUT -OF -BALANCE CONDITIONS. SPACERSMUST BE INSTALLED IN POSITIONS SHOWN.

LOADING AUGER CLUTCH (Mechanical)

The loading auger clutch lever spring is ad-

justed to hold the lever engaged or disengaged.

The collar on the shifting fork rod is adiusted

to fully engage the clutch jaws, with a 1/32"

clearance between the clutch fork and the

clutch.

UNLOADING AUGER CLUTCH (Mechanical)

The unloading auger clutch, Figure 10 shouldbe adjusted so that when the lever is in theengaged position, the clutch jaws mesh fully.

When the lever is in the disengaged positionthe clutch jaws should clear each other by Vs 1o

% inch. Adjustment is made by use of the nutson threaded end of the control rod.

MAINTENANCE

LUBRICATION

Wheel bearings should be repacked every

three years and the bearings taken up to .003-

.010 end play each year.

The drive sheave should be repacked everythree years and the bearings taken up to .0002-

.002 end play each year.

GEAR BOXChange the oil in the gear box once a year.

Refill with SAE 90 all-purpose gear lube. Backlash of the gears should be adjusted to .002-

.015. This is accomplished by shimming.

21

HYDRAULIC DRIVE MODELS

The hydraulic oil reservoir should be filled to

within 4 inches of the top of the filler spout,

approximately 7 gallons, with a good grade of

Type MS lOW, 10W30 or 10W40 motor oil as

shown in Figure 37. When operating in ambienttemperatures of + 10°F or lower, it is recom-

mended using type A transmission fluid. Re-

place the oil filter cartridge after the first 30hours of operation. Replace oil filter cartridge

and clean tank strainer in gasoline every 250hours or once a season thereafter. The tankstrainer screen. Figure 33, is located in the out-

put port of the reservoir and may be removedwhen draining the tank. The oil level in the

reservoir should be checked periodically.

BEVEL GEARSAs the loading and unloading auger bevel

gears wear from use they should be reshimmedto provide as deep a mesh as possible without

FIGURE 37

binding. Add shim washers behind or in front

of gears as required to obtain proper mesh and.030 backlash. These gears do not have ma-chined teeth; therefore they will be excessively

noisy if binding occurs between the gear teeth.

Keep the gear teeth covered with grease at

all times.

SCREENS

Check the grinding screens occasionally.

Screens that have badly rounded edges at the

holes are consuming extra power and should

be replaced if they are badly worn.

PTO SHIELDS

Check the PTO shields occasionally to be surethat they will turn freely and are not dentedbadly. SHIELDS THAT ARE LOCKED TO THESHAFT OR DENTED BADLY ARE DANGEROUSAND SHOULD BE REPLACED. a
