I totally agree with you on the loader bucket cycle time, I plan to ask the dealer about it when I take it in for the 50 hour service. I also think the parking brake pedal could have been more stout.
I have no problem with the brakes or parking brakes at all. The loader tilt/roll is next to dead. I still am thinking of a pto pump to run the hoe only. The hoe is very powerful, great reach and so forth, but it can use quite a bit more "umph" and still not come close to max operating specs.
Have you asked your dealer about the tilt/roll? I think I would have purchased an aftermarket loader if I had been more educated! I wonder if you can replace the hydraulic cylinders with different/stronger ones to increase the loader's capability?
