I was planning to hook up my 6' Bushhog behind the tractor to serve as a counterbalance. Is that a wise choice?
It will work as a counterbalance, but a rotary cutter sticks way out there behind your tractor. If you're in tight quarters, it will limit maneuverability and you'll have to be careful. Also, I doubt that a 6' rotary cutter will cover your tracks on a 7060, so you're probably going to want to get a wider cutter.
A more compact solution would be to either build a ballast box or buy a heavy duty 7' box blade, such as a Gannon with hydraulic rippers (which would weigh approx 1,200 pounds).
Question, what JD model did you compare, a 6065e or a 6065m?
I could also hook on my 6' tiller. That thing is a beast. 400-500 I think at least. It doesn't stick out much at all. *correction - it is 1000#. Very heavy. Although most of the work I'll be doing around the fields will require me to use the bushhog to clean up what's left after pulling the olives. So the conditions won't be tight and that's probably a better choice. Not so for clearing trails though, where it is much tighter.
I also am looking at trading up to an 8' bush hog, I agree the 6' will fit inside the wheels, so not optimal.
The JD that I considered was their 5065E with an H240 loader. It's a fine tractor, but very very expensive vs. the competition.
I guess I feel that it is relatively common for people to not compare apples to apples and then put down the low dollar product. As you mentioned, price could not be touched, but the tractor was more crude. The other manufacturers don't even offer a comparable machine. Now if you had considered the Mpower 75 you would have been much closer in the comparison. I'm not saying one is better than the other, each has their own pros and cons, just that things would have been much closer IMO.
