Just remember, THAT was the way we DID it back in the 40's and 50's..NO separate PTO control..and sometimes that could even be a GOOD thing...
In cast of an Emergency, the tractor operator could hit the Clutch AND Brakes HARD and make a very quick Stop...I STILL prefer that ( although on a larger WD-45 Now)
as I feel I have MORE Control of the Machine..
Anyone here ever operate an AC 50 Combine in Soybeans..?????
If you did, you'd KNOW why I think this way...!!
If you saw a flat rock heading up the canvas..toward the Threshing Cylinder ( and Concaves), you HAD to be QUICK to NAIL the Brakes AND Clutch to try to get that Cylinder to STOP before the rock get to it...otherwise, you had ruined the Cylinder Bars..
Same went for the JD "B", before we got the WD-45's when on the Combine or Baler..
NOW, THERE was a combination..the JD "B" with a Straight Pipe on a Baler ( 116W Wire)...the governors would fully open 52 times a minute..( Plunger Speed),,,!!!
