HELP!!! I have a John Deere Skid Steer and I have am a new to snow blowing here in Montana. I was told by the dealer to put carriage bolts in the tracks for better traction and they have either bent (grade 5 bolts) or snapped off (grade 8 bolts) Now I am told to try "grousers". I have chains that came with the skid steer - should I just use those or buy these grouser attackments? I have to plow a mile to my house and it has a slight grade that I keep slipping on in the snow. Any help would be great. Thanks!
