k0ua, I respectfully disagree with you. I think it is the responsibility of the manufacturer to offer some guidance on how to use rear ballast along with some specific examples. They could give general ranges of appropriate weights, discuss the relationship of distance from the 3 point, how it varies with tasks and terrain, etc. They could add a disclaimer to reduce liability. It then becomes the responsibility of the owner to read this and pay heed.
Your assumption that I'm supposed to have a brain AND some experience AND the knowledge to apply that experience is a false assumption for pretty much any first time tractor owner. I really had very little idea of the potential dangers until I had used my tractor, and I read the manual before I used it. In a similar way, reading about how to use a PTO, or 3 point hitch was pretty meaningless until I had actually used them. Until one of my rear wheels lifted up, I had no real appreciation for the risk, just a general knowledge that it could happen. I could have been badly hurt. Unfortunately, many people die each year from rollovers.
I am extremely grateful to the TBN community and I hope that as I gain experience, I'll be able to contribute as well. It's a wonderful resource, filled with very helpful and knowledgable people.
I realize that people get emotional about issues like this and I'm not trying to start an argument here. I just want to say that I disagree with you about the responsibility of the manufacturer and possibly the dealer. I agree with you and the value of the TBN community.
