Each rotary hoe (39) has a single journal bearing adapter (60) including a bearing support sleeve (61) with a cylindrical outer surface oriented at an angle with respect to the axis of rotation of the drive shaft so as to wobble the rotary hoes laterally in response to the rotation of the drive shaft. |
