I actually leave the load match off most of the time. I don't like the way it always is slowing down the speed when I don't want or need it. Say, I am going up a mild hill or my task gets a littler tougher and it wants to slow the tractor just to maintain an otherwise mild decrease in rpm. It seems like any minor load on the engine activates the load match. It just seems to vary the speed more than I like. For me, my foot on the hydro is the best load match I have. Even doing loader work, I prefer my foot over the load match. My foot does the work without even thinking about the engine load. Maybe it is because I have another hydro tractor without load match and a skid steer is why I don't use it much.
If you like it, use it.
