Combines Found the patent number

Tom this sounds like what Massey Ferguson had on their late 850,860s' as a option. A sensor mounted on the torque sheave of the threshing cylinder monitered the load and moved the hydro lever accordingly.I only ever saw a couple of these and when I was talking to the owner he said it was good for the learner but a little slow to react for the experienced operators.john

I was thinking about this some more today and got to wondering the same thing - if it would be too slow to react. Think about it - the sensor monitors the load on the rotor. With today's high capacity machines, and our high ground speeds, perhaps by the time it sensed a need to speed up or slow down the combine the crop conditions may have changed. I'd think that sensing the crop load at the head or even the feederhouse might be a better place. Any other comments on thisIJ Tom langan

Yep T.lange I agree!!!! I have always tried to assess the crop volume out in front of the header as to how fast I drive in to that area!!!!!

That's what i love about the 72. THE POWER!john

Yer ,Yer I know

Back in the early 80's (still Allis-Chalmers) we worked on a control from engine power. It worked okay in even crop, but I always took over when I saw a tough spot coming because I didn't want to handle a plug. Were working on sensing from auger torque, but then Allis ran out of money and the Advanced Technology Center was closed. You are right, the sooner you can sense the load, the better you will be.
