Thank you for the advice, did not seem to help in my case, but I certainly appreciate your help.When my JD would do that I would try to move tractor slightly, put it in neutral, let tractor settle (release brake) and try again. Always worked, hope it does for you.
Hello :I have the same tractor and had the same problem and I ended up spraying the hell out of the linkage underneath with WD 40 and it now works fineThe 4 wheel drive lever on my RK24 is flexing when trying to engage 4 wheel drive, but does not go into 4 wheel drive.
