| I have found this problem to be hit or miss on most of our tractors, 7220,7240,9230,9330 and 9170 don't do it, 7140,8940,MX220,9350, and STX375 do. The 9350 and STX375 seem to be the worst. FWIW we demo'ed 2 JD's a few years ago, an 8120 and 8320, and the both did it too. It's more of a p.i.t.a. then a problem. Once I get them coupled,and they stay coupled, the rarely if ever blow out again. Makes no difference what I am coupling too either, the STX will blow them out on just about every thing, EXCEPT the grouser blade we put on it to push silage, it never blows those out.......????????.......... | |
