  • Page 5: Introduction

    1 Introduction KEENAN MechFiber mixer wagon 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.

  • Page 6: Warning Notes

    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.

  • Page 8: 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 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.

  • Page 9: Maintenance

    Maintenance Figure 1: KEENAN MechFiber250 Mixer Wagon A properly operated and maintained KEENAN mixer wagon promises to operate trouble-free for years. Regular maintenance of the machine is essential both for long machine life and also to meet the warranty requirements. Refer to instructions in the Maintenance section of this manual.

  • Page 10: Safety

    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.
  • Page 11 d) Exercise extreme caution for possible overtaking traffic at either side when turning. e) Do not stand on the ladder while 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.
  • Page 12 The noise emission level of the KEENAN MechFiber250 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.
  • Page 13 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.

  • Page 14: 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.

  • Page 15: Operation

    7 Operation The simplicity of the KEENAN 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.

  • Page 17: Hitch Height Adjustment

    7.2. Hitch height adjustment The MechFiber250 and 280 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.

  • Page 18: Mixer Wagon Capacity

    Mixer wagon capacity Due to the diversity of the materials available for feeding and the KEENAN 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.

  • Page 19: 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 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.

  • Page 21: 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 (650 lbs.) per tonne of material to be chopped. Rotate the machine for 1–2 minutes at 6–8 rpm.

  • Page 22: Maintenance

    8 Maintenance The KEENAN Mixer Wagon has been designed for optimum performance 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 Mixer Wagon gives you the best results with a minimum of problems.
  • Page 23 C: The automatic chain oiler attachment gives a squirt of oil (approx. 15ml) every time the guillotine 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, turning clockwise applies less oil and anticlockwise more.

  • Page 24: Chain Tensioning

    Chain tensioning 1. Setting tension on primary chain Tension is set on the primary chain to remove excess slack, and to prevent sagging or whipping when under heavy loads. The secondary drive chain is adjusted automatically. Coarse adjustment of the Primary Chain Tensioner is made by adjusting the top mounting position of the tensioner spring where it attached to the front panel of the machine.

  • Page 28: Blade Sharpening And Replacement

    Maintenance blades Blade sharpening and/or replacement, it is recommended that only KEENAN Trained and/or qualified maintenance personnel should perform this task. Blades need to be kept sharp. 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 they reach the point where this is no longer practical, they must be replaced.

  • Page 29: Tyres

    Tyres Each week check the tyres for wear and damage. Each week check the tyre pressures. Optimum tyre pressures are shown in Table 7. This information is given as guidance. If in doubt, please contact KEENAN service. WARNING: When re-fitting and re-inflating tyre/wheel assemblies, a safety cage should be used to prevent possible injury.

    Rear feed-out 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.
