My buddy took my 135 to my farm in WV two weeks ago. We couldn't get the mower on the trailer, but I did get the heavy 8' back blade on. Last year my cousin took his L series Bota with what he called a "Real Heavy Grader Box" up to grade our washed out drives. His "Real Heavy Box" just floated over the high spots, too much work for too small of a tractor. I put the blade on the first hole to angle it a little, and hooked it about 6-8 inches into the side of the drive. Two passes and it pulled enough fresh shale out to level the drive., It was sooo nice not to bottom out in my 4X4 Dodge just getting up the hill. I bought a 70's Woods 6' bush hog to try and keep my field down. When my buddy had the tractor he said they used a 6 footer on it and it pulled it easy. We went over to his farm after dropping my tractor off. Turned out his bush hog was a five footer much smaller and lighter than mine. I suspect the 135 will handle the 6 footer fine. While at his place he was showing me all the barns and said he wanted to clean them out. I saw a big 6-8 inch wide pulley sitting about a foot off the ground. Looked like the kind that went on a drive unit for big flat belts. Got closer and it was hooked to a trans sitting in an old truck frame. Dug deeper and I saw a firewall, dug deeper, on the other side of the firewall was an old 4 cylinder engine. I think we found the drive unit to their old saw mill. He said it was driven by an old Model T truck engine. It was dark and I could barely see, it didn't look like a T engine, but we will go back. He wants to get rid of it. I think it would be cool to restore it as is, as a drive unit, Joe.
