We have an older Edge (2003 or 04, I think) that has aluminum combis. Probably about 4,000 hours on the machine/tracks. The teeth on the grousers are worn down, almost smooth. It has ice calks in place. But the machine is a dog for climbing and sidehilling. On a sidehill more than about 15 or 20%, she just slides all over the place. Even in good snow conditions. And climbing can be quite a chore, requiring up-pressure and very limited blading on anything more than a 40% slope. We get by with it, but it can be a real pain sometimes. When the snow is soft, it augers easily and digs coffins. When the snow is hard, it just spins.
Any thoughts as to the reasoning? Is the machine too light? Are the aluminum tracks inferior in your opinion? Are they just worn too badly? Is this cat poorly balanced? Are we all crappy operators?
Our even older PB300 with steel tracks would hold sidehill and climb 100% better.
