Not sure if you've already pulled the trigger or not, but we've got about 450 hours on ours. The honest answer is that I think we'd make the same decision again, with one big asterisk.
The tractor itself has been pretty good, and overall we're happy with it. We did have the same problem shown in the YouTube video posted above, with the loader valve pivot plate breaking. Not very expensive and not hard to replace, but definitely a design defect. The loader valve has also been a challenge to keep from leaking around the loader spool. I foresee replacing this valve with a different brand down the road.
The factory 3rd function for the loader works well, but it has some flaws. Biggest concern is that the 3rd function solenoid is mounted on the loader crossbeam directly in front of the tailpipe. I keep meaning to make a heat shield for it, but at least make sure your loader is lifted a few feet if a regen starts, otherwise that solenoid is going to get real hot. Less of a concern is the replacement loader valve handle that comes in the kit. It's just pretty chintzy, hollow plastic with no real weather sealing. Considering my right hand is on it half the time, I'd like to have seen just a little more care shown in the handle selection.
The only other legitimate complaint I had is the rattles. Small things, but they need to be addressed or they drive you crazy. You'll find that you need to identify them one at a time, and take some basic remedial measures. The big two were the ROPS lynch pins, and the loader support legs (the ones that hold it up when it's removed). In both cases, some well-placed rubber silenced the irritant. There were more, but hey it's an economy model.
If a backhoe attachment was on your list, Massey does have the best backhoe subframe system in this category. Hands down. Rock solid when it's on, but can be put on or taken off in under 5 minutes. And I mean completely switched between backhoe mode and 3PH mode. Unfortunately, there is one serious drawback here as well: although the tractor is able to handle both Cat 1 & 2 implements, the addition of the backhoe subframe limits the outward swing of the lower 3PH arms. That means that for the most part, you will only be able to attach Cat 1 equipment.
The negatives out of the way, you'll notice looking this machine over that it's surprisingly well laid out. Keep in mind this is an economy tractor. There's nothing fancy, but just about everything is really well done. No sloppy wire looms, no loose hoses. Everything feels firm.
Getting back to the asterisk I mentioned earlier. That has to do with AGCO and their dealer network. We had an awful aftersales experience with our selling dealer. It's a long story, but suffice it to say that the single most important decision you are going to make is who will be the dealer that you buy the tractor from.
