4.5 OPERATING
4.5.1 OPERATIONAL HINTS
Although the mixer is simple and easy to operate,
there are some basic rules and steps to follow to
achieve top mixing performance. It may be neces-
sary to make some trial loads before the ideal mixture
is achieved.
4.5.2 SET-UP
Hay restrictors must be set (you will have to experi-
ment with various settings until the desired length of
cut is achieved).
4.5.3 LOADING
Note : Always remove twines from bale before putting
into the tub.
4.5.4 BIG BALES
Large square or round bales must be processed
alone before they can be mixed efficiently with other
ingredients.
It is very important that dry forages are coarsely cut
first, than the other ingredients can be added while
the mixer is running.
The long stem forages will continue to be cut as other
materials are added and mixed.
4.5.5 LOADING SEQUENCE
After the long stem forages are coarsely cut, other
ingredients can be added and mixed.
The loading sequence may vary but typical sequence
would be :
1- Haylage
2- Corn silage
3- Small quantity ingredients (minerals, proteins,
etc.)
4- Grains, wet and dry ingredients
5- Water or any other liquid ingredients
As a rule of thumb, when all ingredients are added,
allow a final mix time of 3 to 7 minutes.
You may have to make some tries to find the best
loading sequence for your own situation.
4.5.6 ADJUSTMENTS
When processing material, especialy when the mix-
ture consists of a high percentage of hay, there may
be spillage over the side of the tub. To remedy :
- Operate at low speed
- Retract and lock out restrictor plates
- Reduce load size
If spillage still occurs, the optional rubber side exten-
sions may be needed.
4.5.7 UNLOADING
Avoid stopping the mixing auger when fully
loaded. It is recommended to unload the mixed
ration immediately after mixing. A fully loaded tub left
sitting for a long period of time will allow the mixed
ration to settle in the tub and on the auger flighting.
It will take more horse power and cause more stress
on the drive mechanism.
4.5.8 CUTTING KNIVES
The quantity and location of knives that come stan-
dard with the mixer are what we think is the best cut-
ting action with a minimum of horsepower require-
ments.
Removing knives will decrease the speed of cutting
action and reduce the horsepower requirements.
Adding extra knives will help break down and cut long
stem faster but will increase horsepower require-
ments.

13
5.1 SERVICE
5.1.1 FLUIDS AND LUBRICANTS
1. Grease
Use an SAE multi purpose high temperature
grease with extreme pressure (EP) performance
or SAE multi purpose lithium base grease.
2. Gearbox Oil:
Use an SAE 80/90 or SAE 70/80 gear oil for all
operating conditions.
3. Storing Lubricants
Your machine can operate at top efficiency only
if clean lubricants are used. Use clean contain-
ers to handle all lubricants. Store them in an
area protected from dust, moisture and other
contaminants.
5.1.2 GREASING
Refer to Section 5.1.1 for recommended grease.
Use a Maintenance Checklist to keep a record of all
scheduled maintenance.
1. Use only a hand-held grease gun for all greas-
ing. Air powered greasing systems can damage
the seals on bearings and lead to early bearing
failure.
2. Wipe grease fitting with a clean cloth before
greasing to avoid injecting dirt and grit.
3. Replace broken fittings immediately.
4. If fittings will not take grease, remove and clean
thoroughly. Replace if necessary.
5. Pump the grease slowly until a slight film of
grease appears around the bearing seal.
SECTION 5 SERVICE AND MAINTENANCE
MAINTENANCE SAFETY
1. Follow ALL the operating, maintenance and
safety information in the manual.
2. Turn off motor, lock out power source and wait
for all moving parts to stop before servicing,
adjusting, repairing or unplugging.
3. Follow good shop practices
- Keep service area clean and dry.
- Be sure electrical outlets and tools are
properly grounded.
- Use adequate light for the job at hand.
4. Make sure all guards are in place and properly
secured when maintenance work is completed.
5. Never wear ill-fitting, baggy or frayed clothing
when working around or on any of the drive
system components.
6. Never climb onto the machine higher than per-
mitted by the ladder when the motor is running.
Keep others away.
7. Keep hands, feet, hair and clothing away from
moving or rotating parts.
8. Clear the area of bystanders, especially small
children, when carrying out any maintenance
and repairs or making any adjustment.

14
5.1.3 LUBRICATING
1. Use the maintenance record provided in section
5.3 to keep a record of all scheduled mainte-
nance.
2. Grease both universal joints on PTO drive shaft
every 8 to 10 hours (see figure 3).
3. Grease flange bearings on the 2 speed gearbox
drive shaft every 8 to 10 hours.
4. Grease flange bearings (3) on the opening door
system monthly
5. Planetary right angle gearbox : A grease line,
grease fitting located underneath the tub, is
intended to grease the planetary tower top bear-
ing (figure 2). It must be greased once a year
with ten pumps of grease. This should be done
in conjunction with oil changes.

5.1.4 CHANGING PLANETARY GEARBOX OIL
It is recommended to run the mixer for several
minutes to warm the oil before draining. Draining
oil while it is hot avoid sludge depositing.
- Use SAE 80/90 gear oil or SAE 70/80 gear oil.
- Check oil level daily.
- Change oil for the first time after 100 hours of
operation.
- Thereafter, change the oil every 2000 hours of
operation or at least once a year, whichever
occurs first.
- Planetary right angle gearbox contains approxi-
mately 4.5 imperial gallons (5,3 U.S. gallons or
20 liters)
Draining :
1. Remove the air breather cap (see figure 4).
2. Place a catch tub under the gearbox, unscrew
drain plug from the bottom of the gearbox and let
the oil flow out completely. Clean the plug to
remove durt on the magnet.
3. Reinstall the drain plug.
Filling :
A. Filling by gravity
1. Remove air breather cap from the expansion
reservoir and pour slowly the oil. The oil will flow
through the hose and up into the gearbox by
gravity (figure 4).
2. When the gearbox is full, the oil level in the
reservoir will stabilise to the oil level mark.
Reinstall the cap.
B. Filling with an oil transfer pump
1. Unscrew the hose from the reservoir and con-
nect it to the oil transfer pump hose (see figure
4). Pump approximatively 4 imperial gallons (5
U.S. gallons or 19 liters).
2. Reinstall the hose to the reservoir and complete
filling by gravity to the oil level mark.
Attention: If you "pump" to much oil into the gear-
box, the overflow will come out the air breather
on the gear box tower and down on the mixer
floor, etc.
Important: Do not operate the mixer until the plane-
tary gearbox has been filled with a minimum of
4,25 imperial gallons (5 U.S. gallons or 20 liters).
Damage caused by operating the mixer with
lower oil level will not be covered by warranty.
Check daily.
