Page 66: Rotor Speeds
Settings 11.2.2 Rotor speeds The following rotor speeds are possible, depending on the power take-off speed: Variant 1 Variant 2 If the cardan shaft's overload coupling responds too quickly on non-stony ground, at a power take-off shaft speed of 540 rpm or 750 rpm, then the power take-off shaft speed of 1000 rpm with matching gear must be selected. - Page 67 Settings For a normal gearbox: Shifting lever (2) in position (3) = rotor speed 330 rpm with 1000-rpm power take- off speed. Shifting lever (2) in position (4) = rotor speed 440rpm with 1000-rpm take-off speed. For a slow gearbox: Shifting lever (2) in position (3) = rotor speed 330 rpm with 1000-rpm power take- off speed.
-
Page 68: Horizontal Position
Settings The recommended working speed for the rotor speeds is available in the following diagram. 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 69: Working Depth
