IH RT-15 tiller question

Postby Trent M » Tue Dec 11, 2007 11:20 am

I have several questions here about the RT-15, rototiller for the numbered loboys, mostly because I've never seen one, even in a picture, as far as I know.

Are they 3-point?

Otherwise, would it work with a standard FCub?

Also, the hi/low transmission for the numbered loboys, does is work with the FCub?

Is the value of the hi/low and RT-15 tiller comparable to the value of their Howard counterparts?

Does anyone on here have a tiller setup on a numbered loboy that could post pics for me?

How wide is that RT-15 tiller anyway?

Sorry for the multiple questions, but I would like to till with a Cub and the recent prices of the Howard stuff (speed reducer) seems to be out of my price range. :cry: :roll: I thought maybe I'd go another direction.
Got a line on a 184 I'm thinking of checking into. Any other thoughts?

I think I can hit on most of your questions.

Yes, the tiller was standard Cat 1 3-point hitch setup. Otherwise it could work on a cub.

The creeper drive (high/low) gear box on a numbered lo-boy will not work on the standard cub. The creeper drive is mounted in front of the rear differential on the numbered lo-boys, and since the rear differential in a numbered lo-boy is mounted to a frame, rather than using a torque tube like a standard cub, the numbered lo-boys have room for things to bolt on and work. The torque tube prevents you from just bolting on a creeper drive to a standard cub, which is why the Howard Speed Reducers were invented, to bolt in the drive axle.

I'll skip a few, and go to the dimensions. I belive that the tiller was 48" wide.

Photo. I do not have a close-up, but here are a couple:

The tiller is in the TC-131 manual on the manual server so you can see the parts diagrams and picture on a tractor. No specifications or product description, though.

I have an RT-15 and can't find anywhere to get the drive chains for it. Don't know enough about it

I think the RT-15 tiller goes to a cub cadet and is belt driven.

The IH Model 15 is a 42" wide cutting path PTO driven for the numbered series tractors with a 3-point hitch and creeper. This would take some serious modifications to work with a Farmall Cub. It needs the engine to run wide open to be effective which makes the ground speed too fast in first gear (thus requiring the creeper). Turf or Ag tires work fine with the tiller. See the pic in the lower right corner.
I paid $800 for my IH-15 tiller. It is not pretty and quite worn with a lot of tilling hours on it.
The creeper setup came with the tractor. I don't know what these are worth, but they don't fit on a Farmall Cub.

For the cost involved and modifications required, you probably would be better off using a tow behind powered tiller similar to this. http://www.sears.com/craftsman-universal-tow-mount-tiller/p-07124003000P?plpSellerId=Sears&prdNo=1&blockNo=1&blockType=G1
Your Farmall cub could idle in first gear while the tiller engine runs at the proper tilling speed.
