Yesterday I bush hogged and bush hogged and bush hogged. The 350 acres I hunt in Tn is owned by a friend who is a brilliant businessman but not too keen on keeping his place up. It is a mixture of big woods and large open fields. In the past he had a huge tractor with an 18' bat-wing bushog he let us use to keep the place in shape. The tractor broke down, he became involved with business ventures and the land was left untended. Five years later the fields are choked with sweet gum trees, briers and are close to being unreclaimbable.
I tacked an 8 acre field a few days ago with my compact tractor and a 4' bush hog. There were thousands of sweet gum sapling clumps growing out of the roots in the field. To cut one of these clumps I would push it over with my bucket and easy over it with my bush hog very slowly, often taking minutes to grind each clump to the ground.
It took me 9 hours to clear the field.
