Let me start from the beginning. In hydraulic systems, a pump driven by the engine maintains the fluid under pressure. Adding a second engine simply is not practical, which makes power take off (PTO) a valuable element … Road planers, dredges, and other equipment require power from some sort of engine in order to perform their designed function. The regular brakes aren’t powerful enough to slow these vehicles down quickly on their own, so engine braking can significantly reduce stopping distance. Let me start from the beginning. The level of noise is at least 10 decibels over the highest level in normal conversation. The slipper clutch prevents rear wheel lock-up under aggressive downshifting, which reduces destabilizing rear wheel chatter on the tarmac when braking sharply or decelerating into turns.
