  • PTO increaser for Tiller
  • I know it's winter and months away from tilling ground. Has anyone tried using a pto gearbox to increase the pto revolutions? Everybody wants the howard for tilling because it slows the tractor but not the pto. Most people ask if they can run a tiller with a sherman combo, Which many N tractor owners have. The sherman in lower range would slow the tractor BUT also slow the pto. It seem to me that with the sherman if you could add a gear box that increased the pto speed it might work to run a tiller. It could either be a chain drive like my ferguson gearbox or gear drive. Any opinions on this subject?

  • I was given a free tiller many years ago and tried to make it work on my 8N with a Sherman Combo. My feeling was as others have said, First gear low with a Sherman Combo is still too fast for a tiller. I was able to eventually get a small area tilled by doing several passes, a little deeper each time. Another way to run the tiller was to knock the tractor out of gear lower the tiller and control how much the tractor moved with the brakes. I played with it for about an hour one day and gave up. I decided it might be possible to turn an existing garden area, but most of my property has too much hard pan, clay, roots, and rocks for a tiller. Even if I could find a Howard creeper transmission, I decided the tiller mounted solid to the tractor was completely inconvenient and it was going to quickly hammer me and the tractor to pieces. I gave the tiller away to a new victim. For my needs a disk is much easier to attach and does all the "plowing" I need to do.

  • There was a unit similar to that on Ebay a few years ago.
    John Smith and I discussed it on the YT N board. Neither of us went any farther with the idea. That was about the time he built that SOS lawn mower tractor that he had and I had just bought an 8 speed with live pto so neither of us needed it.
    We had considered using double or triple #60 chain. Build a oil tight box and fill it with oil.
    I think if I were to persue the idea I would consider going with a belt drive. Belts will handle all the horsepower a big Harley will put out so would handle a 25 hp N or 33 hp Jubilee. Easier to tighten an open belt than a set of sprockets in oil.
    When I was a kid I worked for a berry farmer in Oregon. He had a Massey 35 deluxe with a Howard rotovator on the back.
    I tilled between the rows of berries. It was the most boring job I've ever had. Creeping along about 1 mph with that thing clanging and jerking behind me. I would Never own a tiller. Give me a plow and disc!

  • A Ford 8N with Sherman combination transmission in low/UD is still too fast for roto-tiller work in most conditions.

  • HiTa Kirk-
    Do you have this Ferguson device? If so, is it installed or will you install it and let us know how it works. I always thought even with a Sherman you still were geared too high to work a tiller and needed the Howard Rotavator to work efficiently. Folks buy an N to work their small gardens with and think they automatically need a tiller. The N's are great little workhorses from small acreage gardens to 400 acre farms. You only need a 2-bottom plow, a 6' Disc Harrow, a 2-Row Spring Shank Cultivator, and a Spring Tooth Cultivator to work a field. Once the field has been plowed, disced, and worked every year, you only need to disc and cultivate once every year, or, every spring and every fall. Breaking virgin ground or a field that hasn't been worked in years is the toughest part.

  • Tim the ferguson unit shown in photo is actually a reducer for the ferguson side delivery rake. I bought this up for discussion to get people thinking. Myself I would rather plow than use a tiller. I have used the howard with a rotovator and the Dearborn tillit.

  • What does that look like on the other side and without the cover in place, Kirk?

  • As I told Tim it's a reducer not an increaser

  • Assuming a reasonably close ratio (1:3 or less) building a low speed PTO chain drive is almost trivial and relatively inexpensive. Once you get much above 1:3 sprocket size is going to complicate things considerably. Aside from the shaft mounting it doesn't matter whether you run it as a reducer or increaser - the chain and sprockets don't care.
