Rod you asked me about the Case/Hesston swather drive, this is it, each wheel controls a wheel like the planitary drive you are used to but these have the added "Trim Steering" on the right hand lever to make slight steering corrections you move the RH lever either left or right to steer cnt

Where I worked they sold Owatanna and versitile swathers. I don't think I have ever seen that type of drive. Was that exclusive to Hestton-Case? Thanks for showing, Rod.

the Trim Steer was a Hesston design for sure and I do not remember seeing any other swather use this excact system, it was very simple and took very little power to operate, the one draw back is changing belts is time consuming but if things are right belts last many years

Here's the 840 setup.

Forgot the back side.

Interesting, it looks as though that machine recently cut because of the straw on the sickle. Nice 14 in the background.

They were real intersting to drive on hills, when going downhill. They would over run the trim steer drive and then you had to feather the lever in to reverse on the side that was overspeeding. Dad put me onto an 850 when I was about 12 yso. SPs were a new concept here then and the idea of gathering 10' of hay and plopit into a windrow, was "obsurd" Dad decided to go out and cut some hay for any farmer who had an intrest. Thats where I came in. I was the operator doing the field demonstrations and driving the machine from farm to farm. To overcome the notion that you couldn't dry hay in a windrow was Dad's job. he was very articulate about adjusting the forming shields to make the perfect "air conditioned" windrow, with a tunnal in the center that a rabbit could run through without slowing down. Elmer Fud hated those windrows, HeHe. Any way I had one very interesting summer on that 850, before it was sold. We went on to sell SPs from 650s and up through the Hesston 6650s through the years.

Tom, I get from the diagram how you get forward and reverse. top idlers full forward engages belts to back shaft for forward and idlers back to engage front shaft for reverse. But how do you get the trim steer? Just curious. Arvin

The drive shaft pullys are also variable speed and they move side to side with one lever to make one side go faster or slower than the other. So for small stering changes you move one of the levers (I don't remember which) to the side you want to turn to. They can certainly be interesting on the down hills as Loren has said.

That makes sense. Thanks.

Bro posted a pic. that didn't have trim steer.
Here is the parts breakdown on 950/1050 SPs

I'm sure it would. Wished I knew whos it was so I could give credit. It was at Rollag Mn. a number of years ago. Nice show.
