for my S590 the auxiliary hydraulic in standard is too high for the snow dump bucket, yes the thumb switch can vary the speed but its getting a pain having the dump slam back to the arms, is there a simple way to reduce this speed say 25% without adding a restrictor to the lines

What is the problem with adding a restrictor? That is by far your easiest option. Just one more fitting between hose and cylinder.

im using a dump bucket for snow, when activating the auxiliary to dump the 1 1/2 cylinders move the bucket quite fast, worse when returning the bucket, slowing it down would make it more comfortable and less hammering on the machine

figured restrictor would put continuous load on the lines, have to give it a try next couple days and see how it works

Let us know what you find. I believe you will be happy after some fiddling around.

One fixed restrictor/orifice in one line is all that is needed to slow speed in both directions. This is fairly common practice when slowing cylinder movement is desired. In fact Bobcat offers a restrictor for some of the industrial grapples for customers that require more precision control.
