i'm more of a sled-head than a 4 wheeler, so ill half to educate yall. First, snomobiles have no gears, just two clutches, a continusuly(sp?) variable transmision if u will. Seccond, you can get plastic ski-skins for just about any sled, that will help u float over the thin mud, just keep up the momentum. Also, get an older sled with a bogie wheel supension, newer sleds have a hi-fax suspension that would wear out verry quickly in gritty mud. Also try to get a fan cooled sled, air cooled won't do well in the summer, and watter cooled won't work unless yer runnin across watter and puddles. Eitherway, get lots o' pics, we gotta c em.
