I have wondered for a while now why the john deeres do not lift the 3 point hitch under load like a case, massey, ih, ?? I have ran plenty of john deere 20 series, 30 series,40series, 60 series, and case 70 series 90 series, and masseys and IH. In the same soil, pulling the same 4 bottom plow,or the same ripper, the john deere system seems to have absolutely no change in pulling, on any of the deeres I have ran, like meaning a 70 series case if I max out the load control for maximum up lift on the implement under load, the implement almost won't even go into the ground, then I back it off slightly and the draft does it's job perfectly, allowing the implement to just cruise and get into shale or rock,tractor lifts. Same as a 90 series case or IH or massey.
On JD draft, I move the draft from min to max and no change under load, No lift at the lift arms. I have the service manual and set the adjustments by their spec,but still no avail, on my tractors or anyones. The dealers here say that our soil is so much more difficult than what these systems were developed for, therefore on case systems they need to "tighten them up" to get performance, Now on JD, they tell me that the system is not made to be truly load sensing, but more "load sensing at position" meaning that if you set the lift arm position lever to all the way lower, the JD will only provide load control at the very bottom, and if you are plowing and the rockshaft is say 1/3 of the way from the bottom, the rockshaft control lever in the cab needs to correspond with the position of the rockshaft. This is fine until you drop the front end of the tractor off a little hill and the ripper lifts out of the ground then you drop it then raise it, Has anyone goten true load control sensing to work on the JD 20-30-40-50 series like 4040, 4230, 4320, 4020, 4250, 4440,4430, and on? just curious. I have a very hard time that Every one I have ran doesn't work, but it seems like the case. Thanks.
