The Aesculap GT578 is a four-tooth upper cutter for sheep shearing equipment in the Econom range. It is the moving cutting plate used with a separate lower comb, making it a replacement component for a shearing setup rather than a complete blade set.

The GT578 is listed for the GT369 head and is also supplied on the Econom NOVA GT694, where it works with the GT598 comb. Owners maintaining an older GT369 assembly can identify it as the upper partner to the GT588 lower plate.

Keep the cutting plates lubricated during shearing and follow the machine's instructions when replacing or tensioning them. Aesculap notes that upper cutters require replacement more frequently than lower combs. Inspecting both components when renewing a cutter helps you plan the rest of the blade maintenance.
