How do most of you guys run your rear axle? In the top two holes, which is the lower position, or the bottom two holes, which is the raised position? I've run my 9650STS 2wd in the lowered position since I got it 4 years ago. Never thought about changing it, since it sits just about level front to rear. However, was thinking that I might want to drop it to the raised position, as it might help the chaffer and sieve to claim a little more grain with the crop traveling 'slightly' uphill. There's a 2-1/2" difference at the axle. Don't know how many degrees that is or if, in the real world, that'll be enough of a change to make any difference. What say ye? Thanx in advance.
We run all ours in the raised position, right back to 9600 through to the present day on 9770, keeps the product on the chaffer/sieves a little longer to add the clean up
An update. We swapped the axle to the raised position today. Sure makes the combine sit higher in the rear, seems like a LOT more than 2-1/2"!!!!!
And I'm quite glad I did decide to swap it, or I probably would have never seen this:
Really wish I had seen it before I had it all together (in that first pic). Had to take everything off again, weld up the flange onto the tube, and put everything back together again. Oh, well - at least we found it before it broke in the field!!
And, finally, a shot of the completed project. Our machine sat pretty well flat before the change-over. At least it appeared that the walkways on both sides of the machine were level. Not so any more. Also, I used to bump my head into the warning flasher arms at the rear, and now they're plenty far above my head. Sure seems like this should help with walking grain out the back end.
I have a 9860 STS runs but only just at 270RPM checked fuel coming out of tank and screen there and fuel filters they seem ok, any other suggestions? What fuel pressure should I be getting at the filter housing? Any help much appreciated.
We have 3 D635 and have always had lots of header height ground following issues. We have done lots of calibrations and changed sensors. Someitmes they work but for the most part we have to run manually. Any one have any solutions? We are thinking of trying headsight header height control.
Considering purchasing 4640 display with auto track as opposed to activating auto track on the 2630 display. Any experience using 4640 display on combine?
We have a John Deere Combine 9500. from 1996.
