Hi Northcoast,
We bought our first Sno-Cat in 1960 and have had several more since then. The support from the people at Tucker has always been more than what we ever expected. I owned and operated an over snow transportation and cross country trail grooming business for about thirty years. Many of the trips were to the top of a mountain to service antennas for communication companies. Six feet of new snow was not uncommon for these trips and for the grooming. I only used Tucker Sno-Cats for this. I have had my Tucker on the same snow on the same day with other machines and in deep snow, have never had another machine able to go the same places. The four track system allows full traction in a corner which a two track will not have. The ride comfort is also smoother for passengers and operator due to the two axles ability to conform to non level surfaces and the ability of the tracks to pivot on the axle housings. Good luck with your search.
