Weighing
4. Operating Principles
The KEENAN MechFiber Mixer Wagon’s main operating functions are weighing,
chopping/mixing and feeding out.
4.1 WEIGHING
The KEENAN MechFiber Mixer Wagon’s electronic weighing system allows the exact
quantity of individual materials to be loaded into the mixing chamber for accurate rationing.
Individual loads can be weighed or successive loads accumulated to give total weight of feed.
See Section 6 (Weighing System) and the Readout Manual for more detailed information.
4.2 CHOPPING / MIXING
Load ingredients in sequence recommended by your KEENAN Physical Nutritionist, or as
suggested in Section 7 (Operation).
For non Bale Processor models, ensure bales are broken up prior to loading. For Bale
Processors, wait until the bale has been taken in completely before adding further bales. As a
general rule, material should be tumbling freely when mixing. If not then the machine is
overloaded and will not achieve the desired mix quality. Mixing is carried out by a centrally-
mounted rotor fitted with 6 angled paddles revolving at 5-6rpm. Each paddle imparts a
shearing action, sweeping the feed ingredients onto the strategically placed knives to
produce a consistent and thorough mix with all types of materials, including baled silage, hay
or straw, roots and liquids.
The angled paddles help mixing by sweeping the material from end to end. The placement of
the blades ensures the materials reach optimum size/length, without grinding it down and
destroying the all important ‘scratch factor’ of the forages producing a MechFiber mix.
Mixing time will be determined by the required chop length. Follow procedures contained in
this manual or consult your KEENAN Physical Nutritionist for further information.
For Bale Processor models, do not load a complete 6x4 round bale onto the machine as it
may potentially be unstable, possibly falling off and causing injury. 6x4 round bales should be
first broken up and then loaded onto the machine in sections; alternatively the bale may be
held in place by the loader until sufficiently chopped down, 1/3 to 1/2 way, to allow it safely
complete chopping on the top of the machine. If in doubt consult your local KEENAN
representative for the recommended safe operation of the machine to suit your particular
application.
CAUTION:
For Bale Processor models, do not load a complete 6x4 round bale, or more than one
5x4 or 4x4 round bale onto the machine at any one time. Overloading the machine
may seriously affect the safe operation and life of the machine, and will invalidate the
warranty.
Chopping/Mixing

MechFiber345 & MechFiber365 Operator’s Manual9Revision A.01 11th Nov 2016
4.3 FEEDING OUT
During mixing, the mixing chamber is separated from the feed out chamber by a Variable
Feed Control (VFC) or guillotine door, thus ensuring complete mixing. The feed out chamber
contains an auger which runs the entire length of the machine.
When chopping/mixing is complete, the feed out tray should be set to the required position,
and the VFC door dropped, allowing the material to be swept up by the paddles and pushed
onto the auger –see figure 2. The VFC door should be partially opened at first, ¼ ways, and
when feed is seen discharging then 15-20 seconds should be allowed before opening the
VFC door fully. Door position and ground speed should be set/used to allow an even feed
out rate.
CAUTION:
The VFC door should only be opened or closed when the PTO is engaged (paddles
turning) when material is in the machine.
4.4 MAINTENANCE
Figure 1: KEENAN MechFiber Mixer Wagon (Bale Processor Option Shown)
A properly operated and maintained KEENAN mixer wagon will give years of trouble free
operation. Regular maintenance of the machine is essential both for long machine life
and also to meet the warranty requirements. Refer to instructions in maintenance section
of this manual. Weekly cleaning of the machine is recommended to prevent corrosion to the
mixer body from old feed. The level of cleaning required will depend on the material
being mixed, but any material which sits or lodges on the machine may both adversely
affect the operation of the machine and affect the quality of the mix if it subsequently
falls into the feeder during mixing. It is therefore essential that routine cleaning and
washing down of the feeder is completed.

Safety
4.5 SAFETY PRECAUTIONS
KEENAN mixer wagons have been designed to reduce risk to a minimum. However, as with
any machine, careful observation of safety procedures is necessary to prevent accidents.
See inside for further details on each section. If you have any further questions please
contact your local KEENAN centre for advice.
WARNING:
Read the following safety section (section 5) before attempting to operate the
machine.
5. Safety
The KEENAN MechFiber Mixer Wagon has many safety features built into its design but
ultimately, safe operation requires the vigilance of the operator and an understanding of
potential safety hazards. The machine is designed to be used as a mixer/chopper wagon for
mixing animal feeds. It should not be used for any other purpose which will affect its
performance or safety.
Figure 2: KEENAN MechFiber Rear View
WARNING:
The operator is responsible for the safe operation of the machine at all times. This
machine should only be operated by one person at all times. The machine should
never be left unattended during operation.
WARNING:
The Breakaway Safety Brake Device should be attached to the tractor at all times.

MechFiber345 & MechFiber365 Operator’s Manual11 Revision A.01 11th Nov 2016
The following safety points are general guidelines. Given the wide variety of possible
operating conditions other safety risks may exist which are not captured in the list over.
a) Always park the mixer wagon on level ground and apply the handbrake when not in
use.
b) Do not exceed 15 km/h (10 mph) when in use/transit. Local road traffic laws will apply
when machine is in transit on public road, on which the maximum permissible speed is
25 km/h. Exceeding this will compromise the life and safety of major components such
as the hitch, axle, wheels and chassis.
c) Ensure the VFC Door is closed and all Feed-Out Trays / Elevators are in the closed &
transport position prior to using on the public road.
d) Exercise extreme caution for possible overtaking traffic at either side when turning.
e) Do not stand on the ladder whilst the feeder is in transit. The mixer wagon should
never be used for the transport of people, animals or objects.
f) Do not stand between the tractor and mixer wagon while it is in use.
g) Use only a PTO shaft with a properly fitted safety guard and correct shear bolt.
h) Always connect the PTO shaft with the shear bolt end to the machine. The operating
speed of the PTO is 540 rpm and the direction of rotation is marked on the front cover.
Always use a well maintained PTO shaft and keep the safety covers in good condition.
i) Ensure all trailing leads, hoses, etc. are well clear of the PTO.
j) Never operate the PTO in “ground speed mode” or drive the PTO in reverse.
k) Make sure all covers/guards are fitted and closed correctly. Never remove guards
when the mixer wagon is connected to the tractor.
l) Ensure the mixer wagon and the immediate area surrounding it is clear of people,
especially children, before commencing operation. Ensure that there is sufficient
visibility for the operator to observe all danger zones and that the tractor is equipped
with mirrors to enable the operator to see both sides of the machine while it is in
operation.
m) When connecting the tractor to the mixer wagon only connect using the ring hitch/hitch
on the mixer wagon to ensure safe coupling. Ensure that the hitch is connected
properly to the tractor and that all pins and clips are properly installed. Then connect
the PTO shaft in the correct fashion. Connect the hydraulic hoses ensuring that the
functions match the indicated valve on the tractor.
n) When disconnecting always ensure that a stand or jack is used to secure the mixer
wagon in the park position and ensure that the handbrake is properly applied. Before
driving the tractor away from the mixer wagon ensure that all hoses and cables are
disconnected.
Safety

MechFiber345 & MechFiber365 Operator’s Manual12 Revision A.01 11th Nov 2016
o) Load only from the side indicated –see figure 7 (auger chamber side), using suitable
equipment.
p) Standing level with or above the machine in order to load manually is not permitted.
Loading should only be carried out with suitable equipment.
q) Regularly inspect all chains (at least weekly), sprockets and moving parts for wear and
check all nuts and bolts for tightness.
r) The ladder on the rear of the mixer wagon is to be used as a viewing point for the
mixing chamber. It should not be used as a means of access to the mixing chamber
nor onto the body of the machine. It is strictly forbidden to climb on the upper brim of
the machine body. The height of the machine presents a potential fall hazard during
entry and exit.
s) The noise emission level of the MechFiber 345 has been recorded at 89.4dB. Noise
emission levels above 90dB would require the wearing of suitable ear protection.
t) The Breakaway Safety Brake device should be attached to the tractor at all times.
Cable ties fix the wire rope along the handbrake handle in place. Cable tie the wire
rope to the drawbar (see figure 4). Fix the other end of the wire rope to a solid location
on the back of the tractor e.g.: using the top link pin. In the event that the Breakaway
Safety Brake device has been activated or damaged, it is recommended that KEENAN
Service are contacted for directions to reset.
u) Routine cleaning may be carried out using a power washer. Isolate any power sources
before beginning. If washing the inside the Mixing Chamber, open the drain bung
underneath the body to allow water escape. Always disconnect PTO shaft from the
tractor & stand on suitably safe ladder or platform. Do not to climb on top of machine
or into the Mixing Chamber.
v) It is recommended that only KEENAN trained and qualified maintenance
personnel enter the mixing chamber.
In the case of an untrained person entering the mixing chamber, at the very minimum,
the following precautionary safety guidelines should be strictly adhered at all times.
1. Ensure the PTO and hydraulic hoses are disconnected
2. Apply the mixer wagon handbrake and disconnect the tractor from the machine on
level ground
3. Use suitable PPE such as protective footwear, eye wear & gloves
4. Personnel should make themselves familiar with the location of all potential
hazards before entering the machine, in particular the location of the top knife and
body blades.
5. Be aware that sharp components may be hidden in or under material within the
mixing chamber
6. The top knife should always be fitted with the supplied guard (Figure 3b) before
entering the machine. Begin by fitting the first 500mm of guard from the rear of the
machine. Then as you enter continue to fit the guard along the full length of the
Top Knife
Note: the machine is supplied with a top knife guard which can be found inside the
driveline covers of the mixer wagon

7. Use a suitable & secure ladder for access to and from the mixer wagon. Note: The
ladder at the rear of the machine is provided as a means of viewing the ration only
and should not be used as a means of access the mixing chamber.
8. Always maintain 3 points of contact while entering, exiting & moving within the
mixing chamber of the machine
9. When entering the base of the body, it is recommended to cover the body blades in
the vicinity of where work is to be carried out.
10.When removing trapped objects, be aware that some machine components may
move unexpectedly when cleared.
11.Take extreme care when moving around inside the body as surfaces may be slippy
SODAGRAIN: Additional safety instructions and warnings are available and covered in a soda grain
leaflet which should be read carefully before soda treating grain. When finished treating grain, clean
out any remaining material in the mixing and/or auger chamber by loading in 200-300 kg of silage or
50 kg of straw and allow the machine to mix before unloading in the normal manner. Note that when
mixing soda grain, the maximum gross load that can be mixed in the KEENAN MechFiber345 is 5,000
kg and for the KEENAN MechFiber365 is 6,000 kg.
WARNING:
Failure to follow the safety guidelines above may lead to accident or injury.

Weighing System
6. Weighing System
The weighing system is designed to be simple to operate, accurate and robust. It consists of
four load cells connected to a weigh box unit (readout box) at the front of the machine. The
system uses 12 volt DC power from the tractor, or battery if fitted. The weigh box unit can be
rotated for visibility during loading and from the tractor cab, but should be folded out of the
line of the tractor wheel for road work. Loads are displayed in kilograms or lbs with scale
increments of 5 kg/10 lb. The unit is capable of measuring up to 18,140 kg (39,999 lbs) with
the appropriate weight bars. The system is maintenance-free, being fully electronic with no
moving parts. All components are sealed against moisture and dust and are resistant to frost
and corrosion. The unit should, however, not be directly exposed to a high pressure water jet.
The weigh box unit may vary from model to model and region to region. A separate manual is
supplied for your weigh box unit, which you should refer to for specific operating instructions.

Set-up
7. Operation
The simplicity of the KEENAN MechFiber Mixer Wagon design is reflected in its low power
requirement. The power required varies, depending on the mix used, the dry matter, and the
amount of chopping required.
If a tractor is at its limit during mixing, this will translate into extra strain on moving parts as
there will be surges in power as the engine recovers during certain periods of the mix.
A tractor that has sufficient power will provide a much smoother drive to the mixer wagon
during all stages of operation.
7.1 SET-UP
1. Ensure the machine is level when hitched up. If the machine is un-level, this can be
corrected by adjusting the hitch height. The hitch height on the KEENAN MechFiber
Mixer Wagon provides a certain level of adjustment from the manufactured height.
2. The PTO shaft should be attached with the shear bolt end coupled to the machine.
Make sure that the PTO guard is in good condition and well secured.
3. Connect the hydraulic hoses (see table 1) from the machine to double and single
acting spool valves on the tractor, as appropriate.
4. Examine the mixing chamber to ensure that:
• All blade covers have been removed, where fitted.
• All spare parts and foreign objects have been removed.
• No damage has occurred during transport.
5. Check the weigh box and ensure the power lead from the weighing system is either
connected to the tractor battery via a direct fused line, 7 pin plug or to a 12v battery
located in the side box of the feeder. To zero the weigh box press and hold the ‘zero’
and ‘minus’ keys together and hold until ‘end’ appears on the screen then release the
buttons. If the power is supplied through a 7 pin lights connection, the tractor lights will
need to be switched on to provide power to the weigh box. If you stand on the ladder,
at rear of the machine, you can check the reading on the weigh box against your
known weight, this may require assistance.
6. With the tractor running, check that the VFC door opens fully and closes completely.
Similarly check the movement of the feed out tray. Engage the PTO and check the
turning of the paddles. The initial turning of the paddle rubbers against the side of the
KEENAN MechFiber Mixer Wagon will generate noise but this will decrease as the
paddle rubbers become more pliable.
CAUTION:
Do not operate the PTO in “ground speed” mode. Reversing the drive on your
machine will cause serious damage.

Note:
A: The design life of hydraulic hoses is subject to the level of wear and tear/usage and also
factors like harsh climate. It is recommended that they be reviewed periodically (yearly) and
typically replaced after ten years of operation if necessary.
B: The maximum oil pressure of the hydraulic system is 3000 psi.
C: If there is a valve chest fit to the MechFiber machine, it is very important to connect the
valve chest hydraulic feed and return pipes correctly. The return pipe is not designed to take
the hydraulic pressure normally seen in the valve chest feed pipe, and so seals and/or the
valve chest itself may be damaged if oil flows in the wrong direction through the chest.
Typically the hydraulic return pipe on the valve chest is fit with a one-way flow valve to
prevent oil being fed to the valve chest in the wrong direction. This is identifiable as a steel
connection on the end of the pipe with an arrow stamped on its side to indicate the direction
of oil flow through it. Oil flows into the valve chest through holes marked P (Pressure) and out
through holes marked T (Tank), see Figure 5 below.
(The valve chest is set up for open centre hydraulics. If the tractor has an alternative
hydraulic system (other than open centre) then contact should be made with the tractor
agent. To alter to closed centre hydraulics, there is a plug that can be fitted to the spool valve
block and is available from KEENAN Service on request.)

7.2. HITCH HEIGHT ADJUSTMENT
The MechFiber345 & MechFiber365 hitch has been designed to allow for a number of
various hitch height options with same components used, the hitch height is normally
selected for the application and set at the factory per the options below.
The main standard hitch assembly is a bolt on assembly and once the main setting is
completed at the factory, it may also be adjusted on farm by moving the assembly up or
down within the bolt holes, or turning the complete hitch over, as it is suitable to operate
facing either way up.
Note:
1: A minimum of four M20 x 100mm Grade 8.8 bolts must be used to secure the Swivel Ring Hitch & the Clevis
Hitch to the drawbar.
2: Care must be taken, when adjusting the hitch height, so that there is adequate PTO clearance and that there
is enough ground clearance below the stand.

Mixer wagon capacity
7.3 MIXER WAGON CAPACITY
Due to the diversity of the materials available for feeding and the KEENAN MechFiber’s
ability to incorporate a wide range of feed types into the ration the capacity of the machine
will vary. Ensure that overloading is avoided at all times as mix quality will be seriously
affected and potential machine damage may result.
Overloading must be avoided because:
• The mix will not be homogenous (evenly mixed), preventing the maximum benefit being
gained from the machine.
• Mechanical failure will result. Due to the nature of the loading this may occur at load levels
below that necessary to break the shear bolt.
The overall amount of material that can be chopped/mixed in one load depends on the
following:
• Machine size.
• Overall dry matter of the TMR.
• The chop length and quality of the material added.
• The loading procedure and loading order of the materials used (this has a major effect on
machine capacity, e.g. the addition of straw first or last).
• Tractor H.P. rating.
CAUTION:
The machine can be overloaded, before the shear bolt breaks. Therefore not
breaking a shear bolt is not an indication that the machine is not being overloaded.
Figure 6: Photograph illustrates a well mixed ration showing
consistent fibre length and integration of forages and grains.

MechFiber345 & MechFiber365 Operator’s Manual19 Revision A.01 11th Nov 2016
Loading and mixing
7.4 LOADING & MIXING
Note: The unique tumbling action of the machine is what carries out the mixing. If the
machine is overloaded or loaded in an incorrect order, or insufficient time is allowed for
proper chopping, this tumbling action will not take place correctly. In addition to reducing mix
quality, it increases the horsepower requirements and reduces the life of the machine.
The effectiveness and speed of chop is determined by:
• The number of effective (sharp and intact) blades.
• The dry matter of the material to be added.
• The amount of pre-chopping of material.
• The loading sequence.
• The total amount of material to be chopped.
• The density of the bale.
Figure 7: Loading the KEENAN MechFiber mixer wagon
CAUTION:
Overloading will seriously affect machine performance and life, and will invalidate
your warranty.
