I dont have enough experience with the xr series to comment on its loader hydraulics, but the mt357hc can lift/lower and tilt at the same time. Cycle speed is reduced due to the amount of flow available, but they do function simultaneously at a reasonable speed. I honestly prefer the hydraulics on this tractor to the ones on the JD 5055E it replaced. The cycle speed is a little slower than the JD, but the motion and control ability is far smoother. My personal fear of the hydrostatic drive not having enough power was unfounded also as this tractor is limited by traction just like the shuttle shift JD.
