Fawazhay - 5/22/2014 23:07 We are going to be in the market for a new to us disc. We are hay farmers and typically plow or chisel before we disc. We have had both tandems and offset discs in the past and have always liked the job the offset did better. But, looking online, there are far more many tandems for sale and they are cheaper. I think I am looking for a Case IH 770 but noticed about 5 times more Case IH 496 models for sale. We haven't liked the tandems because it leaves a furrow on both sides and usually a hump in the middle. It always has appeared to be far more level behind an offset. What am I missing here as to which disc does what type of job and why the tandems are more popular.
