There was mention of using a horse drawn mower on a tractor. This can be done. GOOD farmers had a fast smaller team for mowing and cultivating and mayby harrowing and planting/sowing, and a heavy team for plowing and discing. The smaller team was usually much faster than the heavier team. BUT if using a horse mower behind a tractor, pull it ONLY as fast as a man can quickly walk. ALSO, The mower was made to be put on a 12ft pole for the horses. IF using it on a tractor and not allowing for the rise in the pole, oil in the gearbox will not be where it was origionally ment to be and will soon leak out by the flywheel. To figure oout how high to raise the mower tongue, lay a light 12ft lathe or 1 X 1 along the shortened pole and raise the lathe and pole until the end of the lath is 3ft in the air. Then measure the distance from your tractor drawbar to the ground. Then take flat iron and weld up a hitch below the pole that mounts onto the pole, and also has the drop hith at the same highth as the tractor drawbar. I have used horse mowers, IHC & MH for many years when in my 20s/40s with no problem from them, with me cutting in 1st gear with a 1934 CC Case.
