Figure 7 - Model JR50/75 With Auger Feeder (A –Hammer mill; B –Mixing Tank; C –Dust Collector; D –
Supplemental Hopper; E –Unloading Auger; F –Viewing Windows; No Auger Feeder shown).
INTRODUCTION
This manual has been prepared to make you
familiar with the proper operation, adjustment,
lubrication and service of your grinder mixer. Take
time to be careful and better understand the
efficient operation and care of your machine.
Whenever the terms “Left” and “Right” are used, it
should be understood to mean standing behind the
machine and facing the direction of forward travel.
Some pictorials are used to show guards, doors
and shields removed for easy identification.
Make sure that all guards, doors and shields are
in place before operating the machine. They are
for your protection.
The Art’s-Way JR Series Grinder Mixer is driven by
a PTO driveline of 30 HPto 100 HPtractors. (Figure
7, Detail A.) Using a tractor over 100 HP is not
recommended. It is factory available with a 540
RPM drive.
Hammer mill respective speed should be
maintained as the hammer mill cylinder operates
best at 2800 to 3000 RPM. (Figure 7, Detail B.)
Hammer mill cylinder must not exceed 3000 PRM.
CAUTION: NEVER OPERATE A 540 RPM
PROCESSOR WITH A 1000 RPM
TRACTOR.
Before operating your grinder mixer, select and
install the screen size desired. Sizes are available
from 1/8 to 2 inch openings. For screen selection
guidelines, refer to OPERATION OF GRINDER
MIXER –Hammer mill Screens.
All types of grain can be ground with the hammer
mill. Hay can be ground with a minimum of 1/3
mixer of grain. Material is fed into the hammer mill
where it is ground until it can pass through the
screen size selected. From the hammer mill, the
material is augered into the mixing tank. (Figure 7,
Detail C.) A suction fan takes air pressure out of the
hammer mill housing and delivers feed fines into
the dust collector. (Figure 7, Detail D.) The fines are
separated and then dropped into the mill to mixer
auger.
If supplement is to be added to the ration, a hopper
with a sack cutter is located at the right rear of the
mixing tank. (Figure 7, Detail E –Supplement
Auger.) The best mixing will result if the supplement
is added before grinding.
The ground feed is mixed continuously until the
tractor PTO is disengaged.
The unloading auger pivots at the left rear of the
mixing tank and can swing 180 degrees on the
grinder mixer in a horizontal arc. (Figure 7, Detail
F.) It can also swing in a vertical arc to the limit of
the lift cylinder. Unloading rates up to 30 bushels
per minute can be obtained depending upon
position of the discharge and the type of material
processed.
Viewing windows (4-JR50 and 6-JR75) are located
on the sides of the mixing tank to observe the feed

level during grinding and mixing. (Figure 7, Detail
G.) A spring-loaded mixing tank lid is located on the
top of the mixing tank.
CAUTION: DO NOT OPEN SPRING-
LOADED MIXING TANK LID WHILE PTO
IS ENGAGED AND TRACTOR IS
RUNNING.
Many convenient features are standard equipment
on the Art’s Way JR Series Grinder Mixer including:
JR50/75
1. 9.5L x 15 8 ply tires.
2. Magnet in the hammer mill throat.
3. Tongue jack.
4. Discharge auger hood with spring loaded relief
door.
5. Tractor run hydraulics to power the unloading
auger.
Below is a list of optional attachments available:
1. Auger feeder (hydraulic).
Figure 8 - Model JR50 Without Auger Feeder.
2. Electronic scale, with digital readout.
3. Unloading auger extensions; 3 ft. or 6 ft. Bolt-
on.

PREPAIRING THE GRINDER MIXER FOR OPERATION 15
PREPAIRING THE GRINDER MIXER FOR OPERATION
Remove the shipping banding or wire from the
auger feeder (if equipped), rear discharge cover
and the unloading tube to saddle at the side of the
tank.
IMPORTANT: Remove the bag from the
supplement hopper. Place the screen hook in the
hammer mill door pin (See Figure 9).
Figure 9 - Screen Hook Storage.
Install the PTO driveline storage bracket under the
front hitch with 1/2 inch x 1-1/2 inch bolt and lock
nut (See Figure 10). Maintain tension with the lock
nut to allow movement with 15 lbs. pull.
Figure 10 - PTO Driveline Storage Bracket.
Refer to OPERATION OF GRINDER MIXER –
Auger Feeder Operation.
Install any option that was ordered with the grinder
mixer and shipped as loose equipment. See
instructions packaged with the specific options for
installation.
Install the implement end of the PTO driveline by
fastening it to the input jackshaft with the 5/16 inch
x 3-1/2 inch clevis pin and cotter pin provided.
Spread the cotter pin and make sure the proper
PTO is used.
CAUTION: NEVER OPERATE A 540 RPM
GRINDER MIXER WITH A 1000 RPM
TRACTOR.
If equipped with a bolt-on extension, hydraulic
auger feeder, or roll feed, refer to OPERATION OF
GRINDER MIXER –Unloading Auger Hood and
Auger Feed Operation sections as well as the
ATTACHMENTS section for instructions.
TIRES
Keep tires properly inflated. Lack of pressure can
result in torn valve stems, fabric breaks and uneven
tread wear. Too much pressure can cause undue
strain on fabric, excessive tread wear and allows
the tire to cut in more on wet surfaces. Equal tire
pressure reduces grinder mixer sway when towing.
Recommended tire inflation pressure is as follows:
9.5L x 15
8 –ply tires –44 psi
GUARDS,DOORS,AND SHIELDS
Make sure that all of the guards, doors, and shields
are in place and functioning.
BOLTS AND NUTS
Cap screws, except for shear bolts, used on the
grinder mixer are Grade 5 and if replaced, cap
screws of equal or greater strength should be used.
Grade 5 cap screws are identified by three radial
dashes on the hex head. Refer to the SAE bolt
identification guide (See Figure 11).
Figure 11 - SAE Bolt Identification.
IMPORTANT: Shear bolts must be replaced with
bolts of the same grade
Before operation of the grinder mixer, make sure all
bolts and nuts are properly tightened. Make sure all
cotter pins are spread and not damaged. After
operation of the grinder mixer for several hours,
make sure all bolts are set to proper torque. Refer
to the torque guide (See Table 1).

Lubricate the grinder mixer at regular intervals as
instructed in the lubrication sections. (Refer to
LUBRICATION section.)
PREPARING THE TRACTOR
The tractor must be equipped with a 540 RPM PTO
to match the grinder mixer as described in the
previous section. Make sure the grinder mixer and
the tractor are equipped and set for the proper
RPM.
CAUTION: NEVER OPERATE A 540 RPM
GRINDER MIXER WITH A 1000 RPM
TRACTOR PTO.
TRACTOR HITCH
The hitch for the grinder mixer is designed to attach
to any SAE –ASAE standardized tractor drawbar.
Adjust the drawbar so it is 13 to 17 inches above
the ground (See Figure 12). Extend or shorten the
tractor drawbar so the horizontal distance from the
end of the tractor PTO shaft to the center of the
hitch pin hole is 14 inches for 540 RPM.
Lock the drawbar in its crossbar, parallel with the
centerline of the PTO. Place locking pins on each
side of the drawbar. If the tractor has an offset
drawbar, the offset should be down for PTO work.
IMPORTANT: An improperly located hitch point
may cause damage to the universal joints (U-
Joints) of the PTO driveline.
Figure 12 - Hitch Point Locations
ATTACHING TO THE TRACTOR
Carefully back the tractor up to the hitch. Use the
crank of the jack to raise or lower the grinder mixer
hitch into position to engage the tractor drawbar.
Fasten the grinder mixer hitch to the drawbar with a
hitch pin that cannot bounce out. Raise the jack and
lock into the transport position (See Figure 13).
Attach the safety chain from the grinder mixer to the
tractor (See Figure 14).
CAUTION: ALWAYS FOLLOW STATE
AND LOCAL REGULATIONS
REGARDING A SAFETY CHAIN WHEN
TOWING FARM EQUIPMENT ON
PUBLIC HIGHWAYS.
Figure 13 –Tongue Jack.

Figure 14 - Grinder Attached To The Tractor With
Safety Chain.
For Electronic Scale Indicator, plug the scale power
supply cord into the electrical outlet on the tractor
or to the battery on the mixer frame. (Wire power
cord to the battery as shown in Error! Reference s
ource not found.)
IMPORTANT: On electronic scale applications, if a
bolt and nut are used in place of a hitch pin, the nut
must not be tightened to where it hits against the
underside of the weigh bar clevis.
Connect the PTO driveline to the tractor PTO shaft.
The PTO operating speed of the tractor and grinder
mixer must be the same. The tractor half of the PTO
is equipped with 6-splines for 540 RPM operation.
HAMMER MILL
Make sure the grinder mixer is equipped with a 540
RPM drive when operating with a tractor equipped
with a 5400 RPM PTO drive. The diameter of the
pulley on the jackshaft must be 23-5/8 inches for
540 RPM operation in a hammer mill application
(See Figure 15).
CAUTION: NEVER OPERATE A 540 RPM
GRINDER MIXER WITH A 1000 RPM
TRACTOR.
Figure 15 –Large Pulley - 540 RPM (Shields Removed
For Clarity).
After connecting the PTO driveline to the tractor,
anchor the driveline implement shield chain,
located in the main shield base slot, and the tractor
shield chain to the tractor drawbar.
BEFORE GRINDING
New machines should be operated before
preparing feed. A few hundred pounds of
coarse material such as shelled corn or ground
cobs should be ran through the grinder mixer.
This will remove the protective oil coating from
the mixer cone and any metal particles that may
be in the machine. This will help polish the cone
and prevent bridging. After several minutes of
running the grinder mixer, unload the mixture
and discard. Do not feed this mixture to the
livestock.
DETACHING FROM THE TRACTOR
CAUTION: MAKE SURE THE TRACTOR
IS SHUT OFF, REMOVE THE KEY AND
PLACE THE KEY IN YOUR POCKET.
IMPORTANT: Make sure the auger feeder are in
the saddle before disconnecting.
Disconnect the PTO driveline and front shield
anchor chain from the tractor and place it on the
PTO driveline support bracket (See Figure 16). The
PTO driveline support should be tight enough to
remain in position when rotated from storage
against the frame to use position.
Disconnect the electronic scale power cord from the
tractor (if equipped).
Disconnect the hydraulic hoses from the tractor
outlets.
Block the tires. Lower the jack stand to the ground.
Turn the handle of the jack stand to raise the grinder
mixer tongue off of the tractor hitch. Remove the
hitch pin and safety chain.

18 OPERATION OF GRINDER MIXER
OPERATION OF GRINDER MIXER
TRACTOR PTO ENGAGEMENT
The mixer may be operated by engaging the PTO.
Always engage the tractor PTO with the tractor
engine at idle speed. After the PTO is engaged,
increase the engine speed gradually until the
advertised operating PTO speed is obtained.
Reverse the PTO engagement steps to disengage
the PTO.
For smooth PTO operation and to help increase the
life of the PTO driveline, make sure the tractor is
aligned straight with the frame of the grinder mixer
whenever possible.
IMPORTANT: If mixing while in transport, avoid
sharp and unnecessary turns which may damage
the PTO driveline.
FEED GATE
A feed gate is provided in the mill throat with a
rubber baffle (removed for roll feed installation)
behind it (See Figure 17). The feed gate should be
set to the lowest possible position to allow material
to flow into the hammer mill evenly.
Figure 17 - Feed Gate at Throat of the Hammer mill.
HAY RETARD BOLTS
The hay retard bolts will help maintain uniform
feeding while grinding hay (See Figure 18). The
degree of the retard is adjusted by loosening the
lock nuts on each of the retard bolts, turning the
bolts in (increase) or out (decrease) to the desired
position. Secure the bolts by tightening the lock
nuts.
Figure 18 - Hay Retard Bolts (A - Lock Nut; B -
Adjustable Retard Bolt, 20 Inch Hammer mill Shown).
HAMMER MILL SCREENS
Hammer mill screens are available in sizes ranging
from 1/8 inch up to 2 inch openings. The screen size
needed will be determined by the material and
degree of fineness desired.
