I just cannot seem to buy into the "you just need to practice" idea.
In my case, from day one I did not need any practice to operate my B2910 loader. It just worked as I would have expected. And still does after 18 years. Of course I could be an extremely talented loader operator, but that is highly doubtful.
Certainly it is possible to learn to counteract problems with equipment. Feather a control to an extreme degree if that control is excessively sensitive...in order to get satisfactory results kind of thing.
But do you guys with the same tractor as the OP really feel that your loader is so sensitive that you have to be extremely careful when you operate it?
IF so I would consider that a design deficiency at minimum. But would then agree that action to deal with such a deficiency, I.E., learning to deal with it, would be necessary.
