You've heard my general opinion on your other thread but I will expand a little. If I remember correctly, you're in Maine? One of the things that drew me to the Massey was the dealer. They were very helpful, patient and let me spend a lot of time on the machines without any pressure to buy. They also gave me a good feeling about their service after the sale and so far they have been great. They sent their technician to my house (almost an hour drive) to take care of a warranty issue and fix something that I broke, free of charge. I didn't know anything about the dealer prior to my purchase, it was just a warm fuzzy gut feeling that I got when shopping and so far it's worked out.
There is a dealer in your area, Northwoods Power Equipment?, that I have heard good things about (when I say your area, i mean Maine, whether they are close to you remains to be seen). Unfortunately, when I started shopping they were too far away for me to check out. They have since opened a store in Mass that is pretty close but I haven't been in person yet. They have a demo program where they will deliver a tractor to you an let you try it out for a couple days. Seems like a nice service to be able to spend time on the machine on YOUR property to see how it fits/handles/maneuvers. They also appear to be a high volume dealer so they may do a little better on price, not sure though. I remember seeing someone on one of the forums mention that they made his first 3 payments for him to seal the deal.
As for the tractor, the few things I would change would be the addition of position control for the 3 point hitch and some added ground clearance (again relating to the 3 point hitch). I have some hilly areas in my yard where even at full height, my rake and box blade drag on the ground when I am going back and forth. From what I have heard on here, it's a fault of the sub-compacts since they use "garden tractor" sized tires. Massey just released a new tractor, the 1526, that addresses these issues without getting into a huge tractor. I have considered looking into upgrading, but I won't rush into that. The GC is a very capable machine and my issues with it are minor. On a whole, this tractor is great for how I use it and it more than meets my needs and expectations. I am just a typical "guy" and am now addicted to tractors, so, of course I want something bigger and more powerful.
