Finger Rotor Speed
The finger rotor is set to 900 rpm at the factory, but it can be changed to 600 rpm depending on crop conditions, crop
volume, and the desired amount of conditioning.
In sensitive crops, 600 rpm may be a suitable speed to minimize crop damage. In light crops and dry grasses, 900 rpm may
be a more effective speed. At 900 rpm, crop damage can occur and power consumption will increase.
