It was raining here in Oregon today (rain again? what the hay?) so I stayed home with the wife today. After about 2 hrs she suggested ( her words) that I go work or the Cub or somthing. Yes, or something would happen to ME! I am delayed getting the Howard L-28 Rotovator out to the sand blast shop so I decided to tear apart my Hub City model 22, PTO RPM reducer/ direction reverser. I took some pics and searched for posts and threads relating to the Hub City unit. After I printed some 50 or so pages of posts, I came away with tons of information from Farmallcub.com, and that was only back to 2008.
Special thanks to Jim Becker, Rick Prentice, Eugene, Winfield Dave, grumpy, Trent M, Bigdog, Buzzard Wing, Steve K. Calif, Rudi, Paul B, Barnyard, cowboy, Pony Master, John Cub owner, and many others that made posts in the past about this subject. The post archives are invaluable here! The subject goes on for quite a while so I decided to make a post with some pics. I hope this helps somebody else out in the future. Sorry for the lengh of it.
For those of you that are new to the subject ( as I STILL am), Hub City in South Dakota http://www.hubcityinc.com/ makes a unit that mounts on the back of your Cubs PTO shaft. It does two things: it reverses the direction of the PTO from Counter-Clockwise (C-C/W) to Clockwise (C/W). The Cubs PTO turns C-C/W and the rest of the world makes tractors that turn C/W.
That means that you must buy equipment special made for the C-C/W Cub, Buy a Hub City PTO adapter to use modern equipment, or not use your PTO ( I guess ). The second thing it does is reduce the PTO RPM down to the standard modern 540 RPM used today on equipment for small tractors. Note: Hub City makes many different variations of the Model 22. Some are a 1:1 ratio and only change the direction of rotation. Others do both. Some have female imput and male out put, others are male/male ( see Style A,C,DO,SO ). Many ratios are available from the factory and all of the Model 22's use the same case, so I am guessing that perhaps you might be able to buy different gears and swap them out.
This could be completly wrong so forgive me on that one guys. While the modern version of Model 22 is still in production, the 2.78:1 gear ratio is issue has been put to bed as a myth and a typo error ( thanks Steve for clearing that up). The ratio that they currently make that is best suited for the Cub is 2.53:1. I have the 2.53:1 ratio myself. So you would need to slow down your Cub's engine a bit to get the 540 PTO RPM you are looking for. 540 times 2.53 = 1366.2 engine RPM's on the Cub. But does that really matter much?
Model 230 has a 3.11:1 ratio so at 1750 engine RPM you would have 580 PTO output. Not bad, but would you need to buy a whole bunch of adapters to slip on/weld on ( they make them also ) to make the whole thing work? And what would that add to your price? I don't just don't know about the Model 230. Hey Pro's! would it really hurt to run that mower at 580 RPM's?. What to you think about the Model 230? What about the 2.53 ratio? I'd like your advice on that. Thanks.
For those with a Howard L-28(Hank, and Todd) or S-28 ( like John), they have no need for a Hub City, or other brand PTO reducer. The Howard '28 was made just for the Cub and it takes the high speed PTO and reduces the RPM internally. Jim Becker was nice enough to tell me that the IH A has a PTO that turns C/W and is internally geared down to 540 RPM, and Paul B posted back in 2010 that a Cub Cadet turns C-C/W like the Cub, but at a max engine speed of 3600 RPM turns 514.285 RPM. All good to know and compile here.
You will see Hub City Model 22's with the 2.53 ratio for sale on E-bay, Craigslist, and other sites. They can go from $500-$1000. Ask about the ratio, shaft size, and splines before you by it! If you intend to rototill, you would still be lacking the "creep" gear found on modern tractors, but sadley lacking on the Cub. That means your Cub goes to fast in first gear to do a real good job. There are despeeder units that go (bolt in)in front of the tranny on some hwy mower Cubs out there ( Pro's I can't remember the name). The most sought after is the Howard CD-6. The unit bolts on to the left rear final drive and slows down your Cub by about 1/2 speed in all gears. They tend to go for about 500-1000 bucks used. Howard no longer makes the CD-6.
By reading up on the suject I also found out that the Cub's PTO shaft is 31/32nd's" not 1inch, and it has 10 splines. I hear that Case makes a 10-to-6 spline adapter. Not sure on the price or P/N and if it is still made here in 2011. The output on the Hub City Model 22 is a 6 spline 1 3/8's" size.
If you are looking for the Foot Mounting kit it is P/N 0229-00026. I do not have the gasket P/N yet or any bearing information.

Back in July of 2009 a few members here started working with Hub City and convinced them to do a special run of Model 22's with the 2.53 ratio and proper shaft size for Cub owners. It all looked good. Members were saying "put me down for one!" But the minumum order of units never came about. Very sad indeed.
Here are my pics:
Right now my Hub City unit is stuck on the PTO shaft. I'll try a gear puller or my wifes salad tongs from the kitchen, and maybe some heat if I have to. From the looks of it, my PTO shaft might be bent. Oh,just great. It currently does not have any kind of support. Do any members out there use some kind of a support bracket? Post a pic of it please. Thanks to all.
Update: I have been posting my progress on my Howard Rotovator. My Howards gearbox is NOT like others. I have square gear box with a 1:1 gear ratio. I do require the Hub City reducer/reverser to make it work. It does have the IH Fast Hitch. The other Howard L or S-28 have round gearboxs with a ring and pinon gear for reduction. They DO NOT require/can not use a Hub City reducer/reverser when connected to that implement.
Then his wife left him.
