My 1997 Bigfoot chronically pulls to the left, so much so that I am constantly bumping the right brake to keep it chicken tracking down the trail. I used the brake so much the Argo never gets up to speed and the engine bogs down. It Does it with tires and or tracks on so I think it is something in the braking or a bearing maybe? Wheels on left side all seem to turn normally, no more drag on one than any other. I bought this machine a year ago and have yet to have a good outing in it. Am starting lose my patience with it. Unit has 500 hours on it now, outside of the driving issue it runs like a top. Anyone else ever experience this, appreciate any and all input! Dano
