those 5 ton military road tractors a couple pages back are AWESOME! loud crude and will go through more mud than all get out, we stored one on our farm a couple years back and it was fun to ride in. open top and did that front axle whine! really cool trucks
and while people are talking tractors also...

we have an Agco (used to be Allis Chalmers, now same as Massey-Ferguson) very very similar to this one and pulls a couple tons of farm equipment in mud OVER the front axle without grunting a bit, the front and rear diff lockers are very cool!
