Riding Lawn Mowers

1. I need to remove the rear tire of my Husq. YTG21K46. The tire has a puncture. I removed the rubber cap, the "E" clip and the 2 washers. I've soaked the axle / wheel with penetrating oil. The wheel will not budge from the axle. It's so easy on the front wheels......am I doing something incorrectly?.....am I neglecting to do or remove something. I called your 800 number and that gave me absolutely no help.....I wasted my time waiting. How will I remove this wheel? I don['t have a trailer to bring the mower in so it is incapacitated.

2. On the bottom of the same mower, near where one's feet rest, in the middle, there are written instruction for how to use the cruise feature. It says that in order to speed up the mower, one should turn the dial. I have no dial on my mower. I'm curious of this b/c I've always felt that the rolling speed of my mower is a bit slow.
