I enjoy the power shift. I do find the shifts are somewhat harsh at times. My dealer, Ernie, advised I not use the power shift under heavy loads. But under heavy loads I usually don't find the need to change gears. I also don't use the power shift like a shuttle, moving from fwd to backward.
Maybe I'm a little easier than need be but I'm not interested in having something break.
Mostly use the power shift to change gears when just traveling and with a pto powered implement to get the implement going before starting to move.
