  • Page 20: Useful Information For Mowing Work

    3. Useful information for Mowing Work Mowing is a method of cutting vegetation, which combines several processes in one with the reduction of the vegetation which is to remain on the ground in an energy, work and cost saving way. This provides quick rotting and composting of the biological substance ensuring the re-circulation of the nutrients directly into the soil leading to an additional build up of humus.
  • Page 21 force. The feature of this flail is that noticeably more flails of this type would be required for the same amount of work. Due to the different number of cutting flails required for the “M” Hammer Please Note! Flail and the ”L” Flail different rotor shafts must be installed for each flail type.

  • Page 22: Shredding Bars Usage

    Shredding bars usage The number and shape of shredding bars fitted define the level to which the vegetation is to be mulched. Important features influencing the mowing levels are the shape of the housing with the fixed cutting edges/impact bars as well as permanent or removable U-shaped fixed shredding bars in combination with the active cutting circle and rotational speed of the cutting shaft and cutting flails.

  • Page 23: Engaging

    Engaging P.T.O. Before engaging the P.T.O. of the Flail-Mower please check that the Flail-Mower is securely mounted, that all of the safety devices are fitted and that you are certain that nobody is in the danger area (80m behind the Flail-Mower). Please remember to keep sufficient distance between you and all rotating parts and to keep this safe distance until you are sure that all of the components have come to a complete stand still.
  • Page 24 It is therefore important that the height of the Flail-Mower is so adjusted that it sits parallel to the ground, hence not tilting forwards or backwards. If the Flail-Mower is not sitting parallel to the ground then the effectiveness of the work will suffer and even cause damage to the ground and roots.

  • Page 42: Tensioning And Replacing The Drive Belt

    Tensioning and replacing the drive belt A drive belt is generally included in the drive chain of all products in the Müthing range. The elastic properties of the drive belt reduce the effects of sudden peak loads such as are experienced when starting, meeting foreign objects or the force required to reduce large qualities of dense material.
  • Page 43 New drive belts have a tendency to stretch after initial use. The amount varies with their quality. It is therefore necessary to check the tension regularly after first use. Thereafter the inspection interval can be extended to the normal period. Please note! After the initial fitting the drive belt tension should be checked after 30 minutes work.
