Scruffy, a hydraulic accumulator is something I hadn't even heard of before. In other words, I really haven't the foggiest notion, except that if my Kubota has one, I've never seen it. However, my service manual describes a "Shockless Mechanism" that is "intended to reduce a sudden change of the oil pressure and flow when the three point linkage system begins to going up or stop going up. As a result, operator does not feel the unpleasant shock." It does it by a spool (valve?) and says "A small amount of oil is kept constantly flowing from the pump through the slit into the cylinder port." So my wild guess would be that some tractors have a hydraulic accumulator and others have a different mechanism to accomplish the same purpose. Does that make sense?/w3tcompact/icons/smile.gif
