Page 4: Part I (Service And Maintenance)
PART I (Service and 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 and efficient mixing and feed-out, and low horsepower requirements. -

Page 7: Operating Principles
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 an exact quantity of individual materials to be loaded into the mixing chamber for accurate rationing. Individual loads can be weighed, or successive loads can be accumulated to give the total weight of the feed. -
Page 8: Feeding Out
Feeding out During mixing, the mixing chamber is separated from the feed-out chamber by a variable feed control (VFC) 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). -
Page 9: Safety Precautions
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 center for advice. - Page 10 The following safety points are general guidelines. Given the wide variety of possible operating conditions, other safety risks that are not listed here may exist. 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.
- Page 11 p) Standing level with or above the machine to load manually is not permitted. Loading should only be carried out with the suitable equipment. q) Regularly inspect all chains (at least weekly), sprockets and moving parts for wear, and check all nuts and bolts for tightness.
- Page 12 8. Always maintain three points of contact while entering, exiting and moving within the mixing chamber of the machine. 9. When entering the base of the body, it is recommended that you cover the body blades in the vicinity of where the work will be carried out. 10.

Page 13: 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 (a readout box) at the front of the machine. The system uses 12- volt DC power from the tractor, or a battery, if fitted. -
Page 14: Operation
7 Operation The simplicity of the KEENAN MechFiber mixer wagon’s design is reflected in its low power requirement. The power required does vary, 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. - Page 15 Hydraulic and brake hoses Operation Colour VFC-door Red and yellow Feed-out tray Blue BaleBlend creel Green Brakes White Beetgrid Black Table 1: Hydraulic and brake hoses Note: A: The design life of hydraulic hoses is subject to the level of wear and tear/usage as well as to factors like harsh climate.

Page 16: Hitch Height Adjustment
7.2. Hitch height adjustment The MechFiber270 and 320 hitches have been designed to allow for various hitch height options with the same components used. Hitch height is normally selected for the application and set at the factory. However, if required, the hitch can be adjusted on-farm to level the machine. Some options are shown below in Figures 6.1, 6.2 and 6.3. -
Page 17: Mixer Wagon Capacity
Mixer wagon capacity Due to the diversity of the materials available for feeding, and to 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 the machine could potentially be damaged. -
Page 18: Loading And Mixing
Loading and mixing Note: The unique tumbling action of the machine is what carries out the mixing. If the machine is overloaded or loaded in the incorrect order, or if insufficient time is allowed for proper chopping, this tumbling action will not take place correctly. Beyond reducing mix quality, this also increases the horsepower requirements and reduces the life of the machine. -

Page 21: Specific Instructions For Baleblend Models
Specific instructions for BaleBlend models The creel should be raised before loading bales. Round bales should always be loaded in the center of the machine to allow for the maximum agitation of the paddles. The bale should be gently lowered in the center of the machine onto the tines. -
Page 22: Washing And Chopping Root Crops
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 ton of material to be chopped. Rotate the machine for 1-2 minutes at 6 rpm. -
Page 23: Maintenance
8 Maintenance The KEENAN MechFiber mixer wagon has been designed for optimum performance with minimal maintenance. Chains, bearings and grease points have been kept to a minimum without compromising function. All components are high-quality and provide excellent durability. Regular, routine maintenance will ensure your KEENAN MechFiber mixer wagon gives you the best results with minimal problems. - Page 24 C: The automatic chain oiler attachment (where fitted) gives a squirt of oil (approximately 15 ml) every time the VFC-door ram cycles. In this way, the machine is oiled in direct proportion to the number of cycles and adequate lubrication is assured. There is an adjustment screw on the base of the automatic oiler;...

Page 25: Chain Tensioning
8.1.1 Changing the oil When changing the oil on the KEENAN product, take the steps in the following procedure: 1. Since the oil filler can is higher than eye-level, a suitable stepladder should be used to raise the person above eye-level. Being above eye-level can help prevent any splash or over-fill from pouring onto the user’s head. -

Page 29: Maintenance For Blades
Maintenance of blades Blade sharpening and/or replacement: It is recommended that only KEENAN- trained and/or qualified maintenance personnel should perform this task. Blades must be kept sharp, as blunt blades will increase power requirements. Sharpening must be done without taking the temper from the blades (without overheating). Blades can be sharpened many times, but when this is no longer practical, they must be replaced. -

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 ensure that valves are open. Check tractor hydraulic oil level. Check ram condition and ensure that pins are secure. 3. - Page 66 9. Horsepower requirement is too high Check body blade and top knife sharpness. Machine overloaded. BaleBlend tines may be set too low. 10. Machine is not chopping Blades blunt. Not enough material in body, or material is not heavy enough. Try adding more material, or, in the case of hay/straw, add water or a fork of silage to weigh it down.
- Page 67 17: Blockage at top knife On non-BaleBlend models, load smaller sections of material into machine. On BaleBlend models, check tine height settings. Ensure all feed materials are free from foreign objects before loading into machine. In the unlikely event of a large blockage preventing the machine from restarting using the tractor, it may be necessary to enter the mixing chamber to manually clear the blockage.
