HG and OC3 is WAY too fast in 1st gear for most work since it was sold as a row-crop tractor and not a dirt-mover. Oliver sold kits to put an aux trans in made by Trasco in California. Some have made their own like mine. Oliver/Trasco used a modified Ford Model A (2nd A from 1928-31) transmission. Makes a huge difference.
