So I've have 40's and a 45's and recently got a 100 for a winter driver. Was away it snowed and came home and of course the county dipshits packed about 2.5' of snow at the end of the drive. My wife says you're going to have to put the snow shoes on and get the Woodrow ('70 40 plow truck) running and plow this out. I said let's see and dropped to 4lo and center locked it and away we went. I actually figured we get stuck and I'd get one of the other truck and winch it out, but it was a champ and busted through that and almost made it up the entire drive uphill in one shot - it was a wet and heavy 7-8" (of snow boys, of snow) so I was pretty happy. Duratracs help for sure they've always been much better in snow (had them on other trucks) then the BFG/AT's on the 45 or the BFG/MT's on the 40.
