I picked up a 12' long, wide flange beam which is 12"x12". My book say it is between 70# - 120# per foot, depending on flange and web thickness. I plan on making a drag to help level large areas. I have about 2 acres I need to level in two weeks. I was planning on adding "wings" to the beam which would carry material ahead of the beam and prevent it from rolling. My question is, should I mount it solid to some type of coupler and push it or utilize it like a drag with chains. The complete beam should be about 1,200# when finished, so it may not need any down pressure from the machine to do a good job. If mounted solid to the machine, I could utilize the float function also. A soil conditioner works well also for leveling, but I don't own one yet. The beam was inexpensive, so I'd like to give it a try. Also the beam is 12' wide vs. about 6' or 7' when the soil conditioner is angled. Any other suggestions?
