My Dad had one that he used as a garden tractor back in the '50s. It pulled a one bottom plow that was made special for the tractor. It had a long steel beam that ran under the tractor and attached at a couple of points. It was raised and lowered by a long Johnson bar bolted to the rear axle. Took him some fiddling to get it working right but it would plow OK.
He dug up an old sickle bar mower for it to mow a 5 or 6 acre field next to the house. Big fight getting the mower to work every spring, but after the initial battle, it did OK too. The thing was a mass of rust.
Later on he relegated the H to "sprayrig" duties to keep the bugs out of his nut and fruit trees. Ran the pump off the PTO. Got rid of it sometime in the late '60s or early '70s. Needed tires and he couldn't find any at a good price. Besides, he'd upgraded to a JD40.
Dad's H looked very rough but always ran good, even after sitting all winter. The first job I had was working for a neighboring gentleman farmer. He had an H that looked like new, not a scratch on it. Even the brakes worked. But it had ignition problems and would often revert to running on one cylinder.
While working for him, I used the H to bring grain from the field back to the barn in a graincart. In apple season, I'd prowl his apple orchard with the H and a wagon picking up crates of apples the pickers left by the trees.
The H would do a lot of work with its 12HP. Loved the hand clutch and having a brake pedal for each foot.
