A prime mover transfers power to a separate hydraulic circuits via a power take off (PTO). In some situations, a peak torque demand in one of the hydraulic circuits may cause the total torque of all hydraulic circuits to exceed a rated torque at the PTO. An apparatus measures hydraulic fluid pressur...
