I have seen two ratios advertised, and that's 4:1 and 6:1 -- I have some old 6:1's that don't run, and if you look at my garden creeper, it has a new 6:1 on it. The problem with that on a DB is that it sticks out too far and no room. --I did a test fit a long time ago and saw that wouldn't work.
Need compact jackshaft of some sort.---David - Bradley did make a reducer for them, but I never could find one, so I know that it's possible to make one!
Another idea I got is to go hydro drive, and pack everything in close. hydro motor on top, pump down low, hyd. tank high, ---well you get the idea! lol!!
