Five inches of ice on hills with sharp turns doesn't care how big or small you're tractor is, if you can't steer, you're just going to make a bigger project of getting out of a ditch. We have big tractors, you guys act like you have big tractors but in reality big tractor owners are not members on a hobby farm site. Big tractors start about 150HP, the rest are nothing more than landscape equipment..
A female friend was telling about her BF sliding off the road while plowing and getting his pickup stuck. He called his buddy at the wood yard down the road, who came up with a tractor to pull him out... and slid off the icy road right next to the pickup. So they called and got a payloader to come help them out... he slid off the road right next to the tractor. So they brought up ANOTHER payloader,... who also slid off the road into the previous one.
She never did tell me how they got all 4 pieces of equipment out.
