Got to play with a new full tracked Cat 257B skidsteer loader! Wow what a machine pulls grade as nice as anything you could use and spins 360 on grass without tearinmg up the sod! Every bit as much pushign on a solid footing as any wheeled skidsteer and glides over a sand septic mantle nearly perfectly. OK steerign on sand is just as horrible as any skidsteer, (ruts) but there's no compaction. Walkign in boots beside the tracks you sink in twice as much. Very nice but at 60k CND I doubt I'll get to enjoy the terrific suspension and high speed floating ride for quite some time. I'd luv to hear what others have tried for any skidsteer loaders. My NH 555 is light years ahead for stability and usefulness than any Bobcat I've tried (444 and a 847) but is outclassed by that Cat. Now I only paid 1/6 the price too.
