Because I read this from CCM's FAQ on TnT:
Can I use 2 hydraulic sidelinks? We do not recommend use of 2 hydraulic sidelinks. If you are doing this so you can exert down pressure it is not a good idea to do this. Most 3-point systems are not designed for the added down pressure force and will prematurely fail and cause unsafe situations with the added down force.
Well, I have to disagree with CCM. 3RRL has them on both his and his wife's tractors and has had no ill effects. Has had them for many years and hundreds of hours with no problems. Now I do not know if he uses them for down pressure, but I do know that he is able to get twice the angle that you would normally be able to get with just the normal 1 adjustable side link. If you were to build your own hydraulic side link in a manor to only allow tilt in one direction to get maximum tilt, you too could have down pressure exerted and only have 1 hydraulic side link. That may be more of a problem than having the 2 hydraulic side links in my opinion.
I think what CCM wants or is implying that you need to buy your hydraulic side link from them or you will end up with something that might cause a problem. They also push their hydraulics with the DPOCVs, say that if you don't have it now, you will at some time. They also say this
2. Why does CCM sell hydraulic toplinks with check valves? Safety first is the main reason. OSHA and the EU require piloted check valves as a safety on agricultural and industrial equipment when an object is lifted with a hydraulic cylinder and has no mechanical safety catch.
If this is true, then I guess about every tractor sold in the United States is breaking the law. I know that none of my tractors have them, and none of the tractors that I have ever seen at dealers or AG shows have ever had them. I guess that CCM knows something that no one else knows.
Don't get me wrong, CCM sells some great stuff, I have one of their tillers and it is great, but my thinking is that some of the stuff that they say is for merchandising purposes.
But then I may be all wrong, after all I only know what I read on the Internet.
