I just recently bought a used 1710 with 85 hours on it. I have put just a little over 20 hours on it.
I really like it very and it have been very productive tractor. If I was ordering one, I would order it with SSQA.
I just priced adding SSQA to put on mine but I decided to go with a BXpanded Piranha tooth bar for now.
I have used my 1710 for many tasks and it has been very useful.
