I have a new to me orange tractor with an LA1353 and I used it to move round bales around for the first time this weekend. At one point the tractor was in motion and, for visibility reasons, I lowered the loader and to my surprise I had an RPM drop before the governor compensated for it. I then raised it again and the strain on the engine was hardly noticeable. When lowering it again the engine took on a noticeable increased load. In my mind the struggle should be to lift the load, not lower the load. Why is the tractor having to work harder to lower than to lift? I was hoping someone could make this make sense in my brain.
