1. Introduction KEENAN MechFiber Mixer Wagon and KEENAN MechFiber Bale Processor Thank you for purchasing a KEENAN product. The KEENAN MechFiber Mixer Wagon is a TMR feeder with a difference. The original KEENAN mixer wagon became a market leader due to its reliability and durability, founded on simplicity, fast efficient mixing and feed out and low horsepower requirements.
2. Warning Notes Please read this manual carefully before operating your new machine, paying particular attention to the warning notes, explained here. There are 3 different types of notes, as follows: WARNING: Texts with this symbol contain safety information. They warn you of serious dangers, possibly involving accident or injury. CAUTION: Texts with this symbol draw your attention to a possible risk of damage to your KEENAN MechFiber Mixer Wagon.
3. Warning Signs Read the operators Danger of flying Stay clear of sharp Do not open or remove manual before objects. safety guards while the blades. Keep a safe distance machine is connected to using the machine. from the machine. the tractor.
4. Operating Principles The KEENAN MechFiber Mixer Wagon’s main operating functions are weighing, chopping/mixing and feeding out. 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.
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 –...
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.
Page 11
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.
Page 12
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.

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.
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.
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.

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...
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.
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.
OPERATING THE KEENAN MECHFIBER MIXER WAGON LOADING THE KEENAN MECHFIBER MIXER WAGON GENERAL • Park on level ground. • Ensure the variable feed control door (VFC) (guillotine door) is closed. • Do not start PTO when VFC door is open. LOADING AND MIXING SEQUENCE •...
OPERATING THE KEENAN BALE PROCESSOR LOADING THE KEENAN BALE PROCESSOR GENERAL • Park on level ground. • Ensure variable feed control door (VFC) is closed. • Do not start PTO when VFC door is open. LOADING AND MIXING SEQUENCE • Set paddles running at 6-8 RPM for all bale types.
SPECIFIC INSTRUCTIONS FOR BALE PROCESSOR MODELS The creel should be raised before loading bales. The bale (round bales) should always be loaded in the centre of the machine so that it gets the maximum agitation from the 6 paddles and the full effect of the rings. The bale should be gently lowered in the centre of the machine onto the tines.
WASHING AND CHOPPING ROOT CROPS With the machine stopped add the root material to be washed and chopped. Ensure that there are no stones or foreign objects hidden in the roots. Add water at approximately 300 kg (650 pounds) per tonne of material to be chopped. Rotate the machine for 1-2 minutes at 6-8 rpm.
Each week check the condition of the chain tension arms and adjust as required. There are two chains used on the KEENAN MechFiber345 & MechFiber365 models. The primary drive chain (ASA120) drives the idler shaft and the auger shaft from the input shaft (see figure 9) MechFiber345 &...
and the secondary chain (ASA160SH) drives the rotor. Both chains are tensioned by spring assemblies on the slack side of the chain. Primary Drive Chain ASA120 Links 92 (inc. joiner) Pitch (mm) 38.1 Pitch (inches) 1.5” Chain length (mm) 3,505 Chain length (inches) Rotor drive chain ASA 160...
Figure 9: MechFiber345 & MechFiber365 Oil Level CHAIN TENSIONING With use, the drive chains will extend slightly over time. To compensate for this, all KEENAN MechFiber machines are fitted with a tensioner mechanism on the slack side of the chain. The Primary Chain Tensioner comprises of a linear tension arm which is held in position with a lower connecting arm.
Page 27
1. Setting Tension on Primary Chain The Primary Chain Preload tension is set by adjusting the upper spring seat above the tensioner arm. The spring assembly is fitted with an adjustment indicator which uses the upper edge of the spring as its marker. When it aligns with the green or “OK” portion of the decal then the tension is set correct and does not require adjustment.
Page 28
The upper spring seat is an internally threaded sleeve which sits on guide shaft. It has a shoulder for the spring to seat against and a hexagon section at the top for adjustment. A similar sized hexagon nut is used to lock the seat in position. To adjust first remove the 2 wrenches from their storage location on the front right face of the drive system reduction gearbox.
GREASING The KEENAN MechFiber345 & MechFiber365 are fitted with a 13-port central greasing manifold as standard, located at the right side of the machine, inside front cover. It allows greasing of all the inaccessible grease points of the drive system of the machine from that one location.

NUTS AND BOLTS After the first day, and regularly thereafter, inspect wheel nuts and tandem axle U- bolts (where fitted). After the first week, and each week thereafter, check all nuts and bolts, including bearing nuts, for tightness. General Torque U-Bolt Diameter (mm) Tightening Torque (Nm) Stud/Bolt type...
8.10 WHEELS Each year lever off the hub cap, remove the split pin and castle nut and remove the hub. Check seals, bearings, brake shoes, springs, studs, and all other internal parts. Replace worn parts, re-grease and refit. Note: When re-fitting the wheels, tighten the castle nut until resistance is felt (do not over tighten). Release the castle nut 1/6 of a revolution, check for movement in the hub, and if none, re-fit the split pin.
8.12 SIDE & STUB FEEDOUT ELEVATOR (WHERE FITTED) An elevator system requires regular maintenance in order to achieve optimum performance. Every week the elevator needs to be checked to make sure that the belt is running straight and not wearing unevenly on one side. If the belt is not running straight then adjust the tension by adjusting the tensioner nut on the side and run again to check.
8.13 Axle Maintenance Tightening and retightening wheel nuts The following points should be followed for tightening and retightening of wheel nuts: 1. Impact wrenches should not be used as the impact torque maybe excessive. 2. Wheel nuts should be tightened diagonally every time in conjunction with a torque wrench.
9. Maintenance Checklist Daily Cleaning: Clean all old feed from around the body to prevent corrosion and damage to paint. VFC door: Before using the machine, check that the door opens and shuts fully and operates smoothly. Wheel nuts: Check torque settings. Oil Sump: Check the oil level and replenish with Total/Finol Chainac MP oil as required.
Yearly (end of season) Drive System: Open oil bath drain bung and drain off existing oil. Wash off all dirt and old oil, using paraffin, then dry. Refill bath with new oil to required level (see section 8.2) and run machine for 5-10 minutes to ensure all chains have been lubricated.
