I am new to the forum although I have been reading for a while. I have found a clean 1998 JD 770 for sale. It has 300 hrs, 4WD, power steering and 60"MMM for $8500. Does this sound like a good price. I would also like to install a loader. Can I mount a 420 loader? Will it interfere with the mower? Thanks in advance for any feedback. Steve
