Back in the 70's I mowed a 4 acre yard with an old IH. horse drawn sickle bar. As long as you kept the sections sharp and didn't let it get really high it did a great job. I never had anyone to ride on it. I pulled it with a 1939 B Allis Chalmers that I picked up and did a bunch of work on to get it back into running order. It had spun a rod bearing. I turned the crank with a dial caliper and a roll of emery paper. I ran that darn thing for seven years before I sold it. I love the old iron. It was built to be nearly indestructible. Things just aren't built like that anymore. Great job on bringing it back.
