Reasonable decision. I've heard the GT6000 is a decent machine. Care for it and it should do fine. Congrats and good luck!I bought a inexpensive old tank of a mower- an old craftsman GT6000, six speed manual.
Plan on putting on some new tires and hopefully running them with low pressure to help with the ride- It has been a few months since my other mower gave up and had forgotten how bumping around on a mower for 4 or 5 hours feels...!
