Can anyone educate me as to the drive line mechanics of the Sportsman 6x6 or Big Boss 6x6? Polaris makes rear tracks for these machines but sez they are not for use on the Ranger 6x6. What is it about the Sportsman and Big Boss that accomodates these tracks that is different from the Ranger? I know that on the Ranger 6x6 both rear axles and all four rear wheels are geared together and drive as one unit. How is the Sportsman different? Does it drive only through one axle with the other one being just a coaster, or something else? I guess that I could find a shop service manual and figure it out, but hope that someone in the forum might know. Thanks for any technical information.
