  • Page 7: Safety

    • When the MAXICUT 920 is in transport position, it is important that the side sections are lowered in the transport hooks before driving on public roads. Likewise, this secures the control levers against accidental operation.

Please refer to the table of contents, where the titles for the relevant topics can be found. The main points in the instruction manual are divided into 5 key sections: •...

  • Page 12: Description Of The Machine

    By default, there are strong bearings. MAXICUT 920 in work mode MAXICUT's intended purpose is harvesting, for example, corn, sunflower or rape seed. The ma- chine's total weight and the nature of the soil play a large part here. The machine is most effective when the knife-drum is completely filled with water and the soil is completely dry.

  • Page 13: Limitations In The Use Of The Machine

    MAXICUT Limitations in the use of the machine The following describes what the machine may/must not be used for: • The machine may only be used for tilling organic plant material in agricultural areas that have been culti- vated. Those areas to be tilled must have been subject to normal agricultural maintenance, i.e. without sig- nificant bumps or holes.

  • Page 14: Connecting And Disconnecting

    MAXICUT Connecting and disconnecting Connecting The MAXICUT 920 can be fitted with 2 different types of features. One feature designed for installing in the tractor's three-point suspension; the height adjust- ing via the suspension. The machine can also be fitted with a hydraulic feature that adjusts the height via hydraulics, as well as hydro-clips.

  • Page 15: Disconnecting

    MAXICUT Furthermore, the timing belt cannot be lowered if the tractor's motor is switched off. If the plate equipment is installed on the machine, 1 extra double-acting hydraulic outlet is required to adjust this.

    The main frame and knife drums will then also be horizontal in relation to each other. Fig. 4 Here you can see the MAXICUT 920 at work. The main frame is horizontal while the individual knife sections have the opportunity to move.

  • Page 17: Adjusting The Side Frames

    MAXICUT If the machine is installed with hydraulic pull, there are various adjustment options. It is pos- sible to adjust the cylinders (A) as there are different thicknesses of hydroclips with the ma- chine. It is also possible to move the feature up and down in 2 different flange plates (B and Fig.

  • Page 19: Driving And Operating

    MAXICUT Driving and operating Proper operation is important in order to get optimal performance from your MAXICUT. This applies not only to working in the field but also in terms of safety. It is therefore crucial that you have thoroughly read the safety precautions that cover the machine. Unfolding and folding Unfolding and folding are conducted with the tractor in park.

  • Page 20: Folding

    MAXICUT It is extremely important that the hydraulic lever that goes to the hydraulic weight  distribution of the machine is in float position during work in the ground so as not to damage the hydraulic system (the large cylinder lifting the side frames. The hose marked with: Red) ...

  • Page 21: Turning In The Field Or Headland

    MAXICUT Turning in the field or headland When one turns in the headlands and fails to raise the machine up on the timing belt, it is important to jump 1 to 2 pulls over. That means one must drive in every second or third pull to protect the machine and, in particular, bearings and rubber dampers.

    MAXICUT Extra equipment It is possible to equip the MAXICUT 920 with different types of extra equipment if necessary. - Wave plates with different widths (wave heights) and design - Grass drums (Smooth steel drums for grass areas) - Mole planks (Primarily in combination with Grass Drums)

  • Page 24: Power

    MAXICUT 0. Verify that the sections are completely lowered and the machine is unfolded and lowered to the ground. 1. Pressure is put on the plates, after which the lever is put into float position. If the machine is raised up on the timing belt during turning as recommended, the plates are lifted off the ground and one doesn't need to do anything else.

  • Page 27: Installation

    MAXICUT Installation When replacing drums, a crane, truck or similar lifting equipment will be required. It is recommended that the drums be emptied of any water before disassembly. This is done both to facilitate the handling of the drums after disassembly, but also to secure them against frost.

  • Page 28: Power

    MAXICUT It is possible to equip the machine with mole planks, which are mainly intended to even out mole holes and other uneven grass areas. The mole plank is therefore mainly intended to be used in combination with the grass drums. Fig.

  • Page 29: Hose Markings

    MAXICUT It is possible to install saw equipment separately or in combination with one of the other pos- sible options. The saw equipment is installed with a hydraulic fan and has 16 outlets distributed over the working width. Fig. 16 Hose markings Hose markings Cylinder name...

  • Page 30: Driving And Operating

    MAXICUT Driving and operating Fig. 17 1. When filling the saw machine, use the ladder up to the platform. 2. After use, place the ladder (A) in the transport position and ensure that the transport latch (B) has been locked so that the ladder does not flap out while driving or transporting.

  • Page 31: Maintenance

    MAXICUT Maintenance Good maintenance ensures a long life for the MAXICUT and therefore optimal use of the ma- chine. Grease fittings have therefore been installed in places where wear is greatest.  All screw connections must be tightened after the first day of work. Cotter pins and bolts should be checked to avoid breakdowns.

    MAXICUT Worn out parts Fig. 21 The factory blades are fitted with a pro- tective plate (A) between each to pro- tect the bolts and containers. The blades can be replaced as necessary, with 3 to 4 knives installed per row of every one of the 3 roller bearings.

  • Page 35: Replacements And Repairs

    MAXICUT Replacements and repairs  Safety is crucial regarding all repair work on MAXICUT. The following items must therefore be observed at all times, as well as the items under safety at the begin- ning of the instruction manual. All maintenance and repair work on MAXICUT must be conducted only when the ma- chine is lowered to the ground or, is set in transport mode, the tractor has the break on, the engine is switched off and the ignition key is removed, so that the machine cannot move or start accidentally.

  • Page 36: Installation

    MAXICUT Fig. 23 1. The cylinder is emptied of oil by moving the piston carefully back and forth. 2. Move the piston in the middle position, then unscrew the end cap (pos. 3) from the cyl- inder tube (pos. 1). A special tool must be used to remove the cap. If the cap is stuck, it may help to warm up the front of the cap.

  • Page 43: Uninstalling/Installing Of Wheels

    MAXICUT Uninstalling/installing of wheels For uninstalling wheels, the timing belt is lifted off the ground. The wheels will thus be free of the ground. The wheel nuts are removed and the wheel can be replaced. After installing the new wheel, screw the nuts on and tighten with a "firm hand". Next, lower the wheels so that they are touching the ground and tighten the nuts with 300 Nm.

  • Page 44: Disassembly Of The Knife Drum

    MAXICUT Disassembly of the knife drum The repair is performed on a flat surface with MAXICUT connected to a tractor and unfolded with all 3 knife drums resting on the ground. It would be a great help to have a crane or some- thing similar available for both the disassembly and installation.

  • Page 45: Replacement Of The Knife

    MAXICUT Replacement of the knife If no crane is available, both axles on the side sections must be removed to prevent the drum overturning. Fig. 32 1. The machine is folded out in work position. 2. Soil remaining (A) in between the knife blades must be cleaned/re- moved.

  • Page 46: Disposal

    MAXICUT Disposal MAXICUT must be unfolded. It is crucial to release the pressure from all the cylin- ders. With disassembly/dismounting, attention should be directed towards the weight on the part in question. It is therefore important that this part is supported or lifted up, so there is no risk of crashing/rolling over.
