  • Page 84: Manual Gearbox

    Settings 11.2 Manual gearbox 11.2.1 General Whether you achieve the effect you require will depend on a number of factors in- cluding the operating speed and rotor rpm. Select the lowest possible rpm which will still produce a good result. Too high a rotor rpm will cause unnecessary tine wear and increase fuel consumption.

  • Page 85: Rotor Speeds

    Settings 11.2.2 Rotor speeds The following rotor speeds are available, depending on PTO speed: Rotor rpm Centre gear- Lateral gearbox (PTO speed 1000) Angular gear- Angular gearbox Gear 1 Gear 2 Manual gearbox Angular gearbox If the overload clutch on the cardan shaft is activated too fre- quently in non-stony soils at a PTO speed of 540 rpm or 750 rpm, a PTO speed of 1000 rpm should be selected with the appropriate gear.
  • Page 86 Settings The recommended operating speed for different rotor speeds should be taken from the diagram below. Recommended working speed depending on rotor speed Rotor speed per minute The rotor speed can be changed using the shifting lever. The 1000 rpm power take-off speed should always be selected. If a power take-off speed of 540 rpm or 750 rpm is used, then the input torque increases by 85 % or by 33 % and it does so at the same power transfer.

  • Page 87: Working Depth

    Settings 11.3 Working depth The working depth of the power harrow is determined by the effect you want to achieve. In general, the power harrow should work as shallowly as possible. At the shallowest working depth setting, the power harrow is wider than 3 m when in the transport position.
