ShepFL, I would have thought some one would have answered you by now, So here goes..... I have an old Highway Dept. road roller (2ton) It is 4ft wide, The kind that were pulled to the job site on its transport wheels by pickup or truck. Then flip the roller frame over backward then roll the project out. Transport wheels stick up in the air. Ask around some of the costruction companies, someone may have one sitting around on a back lot just rusting away. I maintain 1/2 mi of private road, most of the time I pull it with my 1/2 ton pickup. Build one-- The LPG tank would work but, cutting the holes in the end of the tank, Explosion chanses, getting the holes in the center , Frame work to support the roller, 2in center shaft through the tank, And the pillowblock bearings to support the roller .
Use 24 or 36 in. well caseing It will be easer to build , The end caps can be laid out on your
welding table, Also the hole for the center shaft can be done now. From my experiences the shaft will be most critical for if it doesn't go all the way through then the stress of turns are all on the end caps and not equalized out on the entire shaft . This is info I have also obtained from a company there in FL . Lawson Cattle Equi.
800-533-2764 Look at how they make ther single roller aerator and there is a pattern you can use to build yours from . All single rollers will have the same basic design.
Sorry this is so long.
Good Luck,
John A.
