Forgive me if this is posted somewhere else but I have looked and could not find it. I am thinking that I would like to have the iMatch QH on my tractor but can not locate anything that tells me if it will work on the 5100E. I am also wondering if it would be advisable to use it as it list the QH as Cat 1 but the tractor 3 PH is cat 2. I do know that I would not want to use implements that are too small as the tractor would tear them up but I have a 7' HD disk that would work on the tractor as it weighs 1000 lbs. I am also looking to buy an 84"tiller and 8' Firmiseeder later this year and it would make changing these out easier. Everything that I have read on the QH makes it sound like it is ideal when you are changing implements regularly and it can get frustrating when you are trying to hook these up by yourself. Thought I would get some opinions on this.
