Patent ID: 7980278

Claim:
A brush cutting head comprising: a hollow support body having a first end, an opposed second end, an outer surface and an inner surface; the inner surface of the support body defining a hollow which extends between the first and second ends of the support body; and a drive and bearing assembly housed at least partially within the hollow of the support body; the drive and bearing assembly including: a drive block mounted to extend within the hollow of the support body at the first end thereof; the drive block including a motor provided with a torque transmitting driveshaft; a first coupling assembly connected to the driveshaft of the motor and the support body; the first coupling assembly being operable to transmit the torque produced by the motor to the support body to thereby urge rotation of the brush cutting head; a second coupling assembly mounted to extend within the hollow of the support body at the second end thereof; the second coupling assembly having a first end and a second end, the second end of the coupling assembly being fixedly attached to the support body; the second coupling assembly including a bearing support member, a bearing assembly housed within the bearing support member and a coupling member; the bearing assembly being mounted in surrounding relation with a portion of the coupling member to thereby allow free rotation of the coupling member relative to the bearing support member; wherein the drive block further includes a motor support member for retaining the motor within the hollow of the support body, the motor support member includes a body provided with a first end, a second end, a generally cylindrical sidewall extending between the first and second ends of the body; the sidewall defining a hollow which receives therein a portion of the motor.
