JD 37 sickle

Why did JD offer 2 flywheel speeds. 850 or 950 at 540 PTO? I assume its crop related, but do not see any reference in the Op manual.

Is there a good place to fine used parts?
 
High speed was for tough-to-cut crops, around here it was prairie wiregrass.

When I was young, we had a #5 and a #8 mower, and both were speeded up to cut that tough stuff. I know it's covered in the manuals for those mowers, bet it is in the "37" manual as well, if you look in the right place.
 
(quoted from post at 22:40:30 01/02/19) Thanks Bob. Was told the mower came from N. Dakota.

LOL! That would probably explain it! (I'm in north central ND.)
 
The no.8 manual has two different sprockets to change the speed of the sickle I think it?s easier to just give the tractor a little more throttle
 
I sold a 37 last year. Trying to get it back. But parts from a 38 and 39 are pretty much the same. I like the trailer mowers, had a 450 couple years ago that would really mow. Problem I had here was the mower would drift downhill in thick cutting when I was on a hill leaning to the left. Flat ground they do great. I have a 9, 39, 8, here now.
 
My mower was an Oliver but same as Moline and Cockshutt. When we got it both tires were filled with fluid so that side drift was probably the reason. And on fairly flat land.
 
When I was using an AC 82T trailer mower it would try to work downhill,put a tri rib tire and weight on the side opposite the cutter bar and it helped a lot.
The NH 456 I now use doesn't try to work its way downhill much on steep land.
