Page 75: 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 76: Rotor Rpm
Settings 11.2.2 Rotor RPM The following rotor RPMs are possible depending on the power take-off speed: Rotor RPM Centre gear- Side gearbox (power take-off speed 1000) Angular gear Angular gear Gear 1 Gear 2 Angular gear Manual gearbox If the overload clutch of the cardan shaft responds too frequently in non-stony soils in conjunction with a power take-off speed of 540 rpm or 750 rpm, the power take-off shaft speed of 1000 rpm must be selected with a matching gear. - Page 77 Settings 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.
