Fischer Australia's latest biological brush, “the twister” is a unique brush that can be mounted either on the front or rear side of a tractor for biological cropping. With a two sided hydraulic arrangement, this model can adapt to any row from a narrow vineyard to a much wider orchard or fruit plantation.

By the press of a single button the two brushes can be brought into operating position either individually or simultaneously and a single command can also position the brushes for transport following work operations

The twister is available in single sided or two sided versions and can be equipped with an independent hydraulic oil circuit, a distributor, a hydraulic heat exchanger, and a hydraulic cylinder that can be used for brush inclination.
