Yes, the Dennis FT machine can be operated at maximum cutter speed and minimum drive speed without causing slip or damage to the brake band. The rear roller is powered via a slipping brake band clutch mechanism that allows infinite speed control independent of the cutter unit. This design ensures that the cutter speed and drive speed can be adjusted separately without causing excessive wear or slippage.
