  • Page 11: Uses

    MaxiRoll is a three-piece roller, on which the sections are independent of each other. Hydraulic weight transfer is standard on all models. MaxiRoll 950/1030 has five axles. Fig. 1 MaxiRoll 950 MaxiRoll is used prior to sowing to crush lumps and afterwards to prepare for shooting and to break down stones.

  • Page 12: Connecting And Disconnecting

    MaxiRoll Connecting and disconnecting Connecting Fig. 2 Connect roller to the tractor's fixed towbar, where drawbar (A) must fit between the towbar forks. Insert pin and raise leg.   Remember to secure towbar pin with split pin or the like.

  • Page 13: Disconnection

    MaxiRoll Disconnection The roller must be folded up (transport position) or extended before discon- nection. Lower support leg to lift roller drawbar from tractor towbar. Remove pin and disconnect hydraulic hoses. Remember to depressurise hoses before disconnecting them. Page 13...

  • Page 14: Setting Up

    MaxiRoll Setting up The machine is supplied with factory settings, but fine adjustment will always be required before use. Numerous adjustment options make the roller more flexible and ensure maximum use. Adjusting drawbar height To achieve uniform rolling, the bar (A, Fig. 3) on the mid-section must be parallel with the ground and the drawbar (B, Fig.

  • Page 15: Adjusting Mid-Section

    MaxiRoll Adjusting mid-section Fig. 5 Extend MaxiRoll fully (see ”Operation”). Check pipe (A, Fig. 3) on the mid-section is horizontal (parallel with the ground). If it is not, adjust the bolts (A, Fig. 5). Fig. 6 1. Slacken the lock bolt (A) 2.

  • Page 20: Excessive Pressure

    Check all the accumulators on the machine at least once a year for leaks and to ensure that the precharge pressure is set correctly. Contact an authorized Dal-Bo dealer for more information. Operating speed An operating speed of 6-10 km/h is recommended, but always operate accord- ing to conditions.

  • Page 24: Operation

    MaxiRoll To adjust the basic setting of the crackerboard, we recommend extending MaxiRoll on a flat surface and lowering the crackerboard until the tines are almost touching the ground. All the tines must be at the same distance from the ground. If the tines on the mid-sections do not have the same distance to the ground as the sides, adjust the draw bar at the tractor.
