YTers,

In looking at a Super C sales brochure, they mention the Hydra-Creeper option. Was this ever built? I've never seen or heard tell of one.

Thanks,
Bill

Bill: Just to add to what Hal, Bob and Andrew have said here are the reductions it gives for a Farmall 130, all this in miles per hour: 1st regular drive 2.3, hydra creeper no load .27, max load .17; 2nd regular drive 3.7, hydra creeper no load .42, max load .23; 3rd regular drive 4.8, hydra creeper no load .55, max load .42 and 4th regular drive 10.0, hydra creeper no load 1.10, max load .94. As you can tell it confirms what Bob said about it not having great pulling ability. If you notice performance in 3rd and 4th are much better under load than 1st and 2nd. I suspect as the hydraulic motor turns faster it becomes more efficient.

One other item that no one mentioned, use of this device requires a special clutch release bearing. This would be the result of that release bearing turning all the time this is in use, as the clutch pedal must be tied down.

Yes, they were built and I saw a complete unit not all that long ago for sale on EBay. I believe the complete unit went for over $1,000 in the auction. In my Super C parts catalog the parts and components are shown in the attachments section of the catalog. It appears it works off of the tractors live hydraulic system by driving a small hydraulic motor which in turn is connected to the PTO shaft on the back of the tractor with a couple of roller chains. There is also a clutch and PTO lever interlock apparatus shown. I believe it would only activate when the tractor clutch was depressed through this interlock system. There is a selector valve in the system to regulate the hydraulic fluid flow for speed control. They were offered for either fast hitch or non-fast hitch tractors. Pretty novel idea for the era.

It was the guys starting price on eBay. He listed it twice with no takers. I watched it both times. I would like to have had it, but I thought $1000 was too steep when you can buy a whole tractor for $1000. Just thought it would make a cool piece to show off with. It would be pretty easy to make one if you could come up with some gearsets.

Bill - the Hydra-Creeper is a clever means to provide an extra, ultra low-low gear. It consists of a hydraulic motor that attaches to the PTO shaft and plumbing to connect the motor to the hydraulic system.

To operate, first the clutch pedal must is blocked down. The transmission is then placed in 1st gear and the creeper control valve is opened. The creeper motor then turns the PTO shaft very slowly thus causing the tractor to move very slowly forward.

The hydra crepper is intended for very slow speed and lightly load operation such as transplanting, etc. - NOT for heavy pulling!!

I see one of those in a book that I have. I think it ran of the pto not sure. and it ran a hydro. pump that turned ground wheels behind the tractor wheeels. This made the tractor have a real low low speed. I think the main use of this was in cultivating or planting maybe. The book did"t really say what it was used for. I never see one in person but they look real neat. Andrew
