Adding some ballast to your tires can cure a lot of hillside problems. Better traction, lower center of gravity and no noticeable loss in power. My dad always used ballast on his 400 series. I can't remember exactly which one he had but it was an early model. My brother has a 420 and dad's came out before that mower did.
My LX172 was very good on hillsides. Being able to lean out on a fender is getting to be a lost art these days with the auto off switch if you get your weight off the seat. I eventually by-passed that switch because it was having problems and I wanted to have the ability to go around the side of a hill better. My new X324 has a much higher center of gravity and it will quit in a heartbeat if you get off the seat to counter-balance any tendency to tip. I'm going to be adding ballast myself pretty soon.
