gear vs. hydro for pulling tiller

[DK35vince]

Some of the Grand L- 30 series Kubota's with the FST (syncro shuttle transmissions) are 8F/8R with optional creeper gear.
Some of the Kioti DK's are the same way.
The creeper gear option makes them 16F/16R

Hi Soundguy,
On the Ford 8N's, I was reading several posts on another forum about the possibility of tilling with these old tractors and the fact that the ground speeds were just too fast. International had the torque amplifier option which got the speed lower, maybe 1.5mph. And I think Oliver's 550 and Super 55 had first gear ranges that were close to that. One fellow said that Sherman made high, low, and high-low auxiliary transmissions for the Ford 8N that allow slow ground speeds in that range. However, another guy said that not only do the Sherman low range units slow the ground speed, but they also slow the PTO speed in proportion due to the fact that they come off the "other side" of the transmission (non-live). True? If that's the case, I assume the Sherman unit wouldn't do you any good for tilling.

I can't tell you anything about the Sherman units because I am unfamiliar with them, but you are pretty much on target with the speed of the Oliver 550 and Super 55s. They are too fast in low gear for tilling. I suppose they are great for pulling a plow (I never tried to do that with one of mine) but for tilling they run a bit too fast.

Frankly, if you haven't had Vidalia onions, you haven't lived!!!!!

I've had Vidalia's onions........I prefer her tomatoes....frankly.

You got er right!
Vidalia onions on a burger, with silver queen corn on the cob as a side! Man I'm making myself hungry.

Yeah, and those Vidalias need to be thick cut for full effect. The corn sounds good too. How bout a thick juicy Ribeye grilled on a charcoal Weber instead of that burger? Slap it all on a big bun and rip away.

Correct. The sherman ( and hupp for that matter ) were pre- aux trannies, and took the place of the tranny input shaft.

They dropped ( or raised ) the ground speed by simply adding gar ranges to the tranny. The pto is driven off the tranny counter shaft directly.. so ground speed changes almost always effect pto speeds. Except** if you use a couple of specific type aux post trannies. One was an everet, and the other was a howard. The howard was the nicer one as it actually replaced some o fthe tranny gearing with mechanical reduction. You could lower the groundspeed to a crawl using the howard.. as it dropped the pinion speed.. but not the pto speed. The howard aux post tranny was made specifically for the howard rotavator.

There was also an evert post aux tranny. it was a piece that actually went inbetween the tranny and diffy.. making the tractor about 8" longer. It accomplished the same feat.. seperating the feed for the pto and pinion drive... Thus you could lower ground speed and retian pto speed.

Sherman and hup pre trannies would let you lower your eng rpm, and keep ground speed and pto speed at 'normal'.. I guess if you had a pto application that didn't require much HP.. and you didn't want the engine revved to 1500 rpm to get pto rpm...You could shift into overdrive, lower engine rpm to a point wher ethe pto was at normal rpm.. etc..

Chris- The Sherman transmission parts are rare and extremly hard to find. How are the service parts on the other makes you have mentioned. If a Sherman goes down it is usually removed and the standard input shaft is installed

The everet and howard aux tranies are very rare... as you stated.. hard to find sherman parts except in extreme circumstances.. except that shermans are fairly plentiful. I see them on ebay for 200-800 all the time.

I hear that some machinist is going to fab parts for the howard trannies, as it is a simple gear set.
