We've got a few tractors on our farm. My dad has three Fords, an 8N, a 9N, and a Jubilee with a loader and backhoe, a John Deere 850, and a Belarus 525 (70hp). In the last couple years I bought a TYM 233 and a Massey 1540.
The Fords are pretty much retired now, they just sit in the shed. The JD 850 (built by Yanmar) is still going strong 28 years later. We just put new rear wheels and tires on it due to the calcium corrosion. It's a heck of a little tractor that certainly doesn't owe us anything. Believe it or not, two weeks ago, we swapped out the original fan belt. 28 years on a fan belt ain't bad. It doesn't have power steering, but we've managed with it. For a bare-bones puller, this is one fantastic little farm tractor.
The Belarus was an experiment. In some areas it's built like a tank, in others (FEL), it's pretty cheesy. We've worked it hard over the 20 years we've had it, but having said that we haven't abused it. The hydraulics could rip the loader right off the tractor if you aren't careful. The bucket is huge, we use it for sawdust and carrying wood. It's loud and uncomfortable, but hey, it was cheap, and this tractor doesn't owe us a dime, either.
My TYM is a little working machine. Outstanding little tractor. IMO, perhaps the best tractor of its size.
The Massey 1540 is a very nice tractor all around. Initially, I had my heart set on a green JD 4000 Twenty series (4120 or so), but the dealer was such a prick I could not justify giving him my business. The next closest JD dealer was much further away so I went to a nearby MF dealer. After using the 1540 around the farm for seven months now, I do not feel shorted by getting the red tractor. It isn't in the same league as the 4000 Twenty series, but then again neither was the price. It really is a nice tractor. Quiet, comfortable, with good features, and the loader is actually made in the USA!
My dream tractor would be a 4520 with a 400cx loader, R4s, and e-Hydro.
With all the work we do on the farm (40 acres of hayfield, hauling wood on pallets for the outdoor wood furnace, random other chores), a 4520 would be sweet.
I don't see us getting rid of the Massey 1540, though. It's a high-quality tractor.
