Chris is mostly right. I have an old school Gravely, large 4 wheel garden tractor with fore, mid, &amp; aft PTOs. No hydrostatic trans - all gear direct drive (4 hi/4lo). It is a 1978 model originally outfitted with 12 horse Kohler but I have adapted a twin cylinder 20 HP Kohler for a bit more oomph.
