Abstract: A shearing head for an animal shearing machine, comprising an upper blade and a lower blade, whereby the upper blade is movable relative to the lower blade. A pressure control device, comprising a rotatable control knob, with which the pressure of the upper blade on the lower blade is settable. The pressure control device further comprises a pressure indicator pin disposed coaxially with respect to the control knob and movable in a translational way. The pressure indicator pin is at least partially visible to a user of the shearing head and the axial position of the pressure indicator pin relative to the control knob is dependent upon the pressure of the upper blade on the lower blade set with the pressure control device.
