Good Afternoon, I found this old post about JD 430 tying problems. I have a 530 doing a similar thing and I hope you can help or point me in the right direction. In the thumbnail you had showing the parts break down, #21 is not returning to the home position back under #14 after I dump a bale, I have to manually pull #21 forward towards the tractor about 1/4 inch before I start a new bale. I have replaced the springs, changed the filter, and check the fluid level. If I reset #21 back under #14, the tying arm will travel correctly, however I also have to apply pressure to the arm when it reaches the RH side to make it click and then travel back to the LH side. It will start to pull the knife blade down, but does not seem to have enough pressure to complete the knife cut. any ideas? thanks in advance Carl
