If it is the shanks than you are either too deep for the machine, ground hard, or running too fast for the conditions. Remember these machine where designed when we where chiseling at 4-5 mph. Now we have bigger MFWD tractors so we are running at 6-7 mph. Watch and see if all the shanks are flexing at the same time. I have seen this make them just about hop out of the ground. IF it is the standard springs then check and make sure there are not any broken ones. They also loose their strength. You may need to replace them. Is this machine new to you??? Is this the first year you have used it or is this just the first time you have had the problem?? The reason I am asking is that the ground is dryer and harder this fall than normal. I am running a gear lower on my JD 4960 than we normally do. I also have noticed that the shovels are wearing faster. The ground is like concrete in places. [Reply]   [No Email]

The type of ground definitly makes a difference. This morning it was pulling like a dream at 6.5 mph. On the other side of the hill it was bouncing like no other at 3.5 mph. My boss has a 712 or 714 that has 9 shanks and it NEVER bounces. I wonder what the difference is? I"m not doubting that we pull it too fast like you said it"s not designed to be pulled over 5 mph. I know that is definitly the problem sometimes. But other times we have to go 3 mph so it doesn"t bounce at all. We have tried to level it, but maybe we didn"t do it right? Is there a secret to setting everything right?? thanks! [Reply]  [No Email]

Usually on a chisel plow you will set it about an inch higher in the front. The draft action of the chisel will rock it forward just a little when you pull it. I am willing to bet that it is the shank springs that are causing the bounce. The 712 and 714 have a heavier spring setup on them. If you can find a set of depth wheels off another chisel then you may try them. The 1710A maybe sucking in too far and then bouncing when it comes back to the set depth. [Reply]  [No Email]
