A simple mechanical governor must overcome friction in the linkages and exert a controlling force. These forces act in different directions depending upon whether the load is increasing or decreasing.The effect of this friction is to create a deadband In hydraulic governors this effect is negated by having oil pressure act as the controlling force.
This simple system has inherent stability due to the the on/off nature of oil being suppled to the system control due to the control land just covering the outlet ports. Oversizing the land would create stability but at the expense of reintroducing a deadband
