PART I (Service & Maintenance) 1. Introduction KEENAN MechFiber Mixer Wagon and KEENAN MechFiber BaleBlend 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.

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.
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.
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.

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. Always park the mixer wagon on level ground and apply the handbrake when not in use.
Page 11
Regularly inspect all chains (at least weekly), sprockets and moving parts for wear and check all nuts and bolts for tightness. 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.
Note that when mixing soda grain, the maximum gross load that can be mixed in the KEENAN MechFiber340 is 5,000 kg and for the KEENAN MechFiber360 is 6,000 kg.
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 MF340 & 360 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 set- ting 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,...
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.

SPECIFIC INSTRUCTIONS FOR BALEBLEND 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. 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 (660 pounds) per tonne of material to be chopped.
8. Maintenance The KEENAN MechFiber Mixer Wagon has been designed for optimum perfor- mance with a minimum of maintenance. Chains, bearings and grease points have been kept to a minimum without compromising function. All components are of high quality and provide excellent durability. Regular routine maintenance will ensure your KEENAN MechFiber Mixer Wagon gives you the best results with a minimum of problems.

After each season, remove all chains by loosening the tensioners and removing the joiner links - see figure 8. Wash off all dirt using paraffin. Dry the chains before soaking overnight in oil and then refit. Figure 9: Front panel of KEENAN MechFiber Mixer Wagon CAUTION: Failure to maintain oil on the chains may reduce the working life by 90%.
CHAIN TENSIONING 1. Setting Tension on Primary Chain Contrary to previous versions of this machine, it is not necessary to adjust the pivotal position of the input shaft housing for normal chain tension adjustment. This should only require attention when replacing a chain. The tension is set by adjusting the lower spring seat underneath the tensioner arm.

11.15.2 Axle Maintenance Tightening and retightening wheel nuts The following points should be followed for tightening and retightening of wheel nuts: Impact wrenches should not be used as the impact torque maybe excessive. Wheel nuts should be tightened diagonally every time in conjunction with a torque wrench.
12. Troubleshooting 12.1 GENERAL TROUBLESHOOTING PROBLEM: SOLUTION: 1. Weighing display won’t work properly Check section 12.2 on weighing. 2. VFC door does not move Check hydraulic hoses and that valves are open. Check tractor hydraulic oil level. Check ram condition and pins are secure. 3.
Page 71
PROBLEM: SOLUTION: 12: Bale goes in too quickly If the bale goes into the machine too quickly, it may place unnecessary load on the tractor and drive line, as well as slowing overall mixing time as the body blades aren’t as efficient at chopping long fibrous material as the top knife.
12.2 WEIGHING TROUBLESHOOTING KEENAN troubleshooting tips on weighing If you experience problems in the operation of the Weighing System, read through this Troubleshooting section first before contacting KEENAN Service. Reading Drifting If the reading on the weighbox is drifting or does not stay steady, the most likely cause of the problem is dampness/moisture in or around the weighbox or cables.
