The Aesculap GT594 is a 13-tooth lower comb for Econom sheep shearing equipment. Its outer teeth curve outward, giving it the flared shape that distinguishes this model within the manufacturer's comb range. Aesculap lists a cutting length of 3.5 mm.

The GT594 is documented for the GT369 sheep-shearing head and is listed among the accessories for the Econom NOVA GT694. Those references provide specific equipment matches when selecting a replacement comb or an alternative lower plate for an existing shearing setup. Match the GT594 part number as well as the tooth count: the outward-curving teeth are a defining feature of this version.

Maintain the cutting assembly according to the shearing machine's instructions. Correct blade positioning, suitable pressure and regular lubrication are part of routine setup, and the plates should be clean and oiled for dry storage.
