Not sure why the find a dealer didn't work - I went to
Find a Dealer and punched in Buffalo New York in the search and got a bunch (a lot more than I have around me alas).
I have a 2024 5520H which is the same as the 4820 excepting it has a turbo on the engine (add about $1500, a bit happier running the 8"
chipper). I haven't had it long enough to really say I've beated it into submission yet. So far .. so good...
The 4820/5520 is a legacy Branson model that's been fairly well proven out. Branson and Tym fully merged so all of the "Branson" tractors are now labeled Tym. I don't know who made the old Long's.. they seem to be an abandoned brand. Montana was a made by one of the parent companies (Kukje which made Branson), although I think it was a contract label.
They did change a few things I'm not entirely happy about. The 3pt is a touch jerky on the way up (reportedly all? most? many anyway of the newer Korean tractors do this now - the started all using some sort of stepper hydraulic which isn't great). I also don't think the loader is quite as overbuilt as the ones made pre-merger were although it's still pretty much top of class weight capacity wise.
The 3 number variants come with some more shine, default rear remote and support more rear ports (the 48/5520 only technically support two and it's an add on). The console & cab is a touch nicer in the 494/574 and there's a rear handle for the 3pt (I'm cabless so I can just reach over the fender.. I could see it being handy for the cabbed version).
I chose it over the 494/574 (same engine 494 is the non turbo 574 is turbo) for a couple of reasons. The 494 has essentially the same front end design as the smaller body 474 except it's wider which puts more leverage on it, this is IMHO a touch under built and if you lurk around the forums there's a person every week or so who blew out their front end (which given the # sold isn't .. to bad.. but also..). They claim they fixed the front end issues this year but when I bought there certainly wasn't enough ground truth data for me to feel comfortable. The rear lift capacity is nominally lower on the 48/55, but if you look at the axle its built heavier so take that for what it's worth. The 48/5520 is also shorter and a touch squatter so I believe it's a bit more stable (or at least looks like it).
My comparison tractors were a handful of kubota's
L4740 (used, almost bought but the seller skeezed me out) an MX5200, and an
L6060. The Kubotas were definitely smoother, the FEL on the 4740 supported lift and curl (the BL200 on the 5520 .. not really.. if you hit juuust the right point it kind of does but it's really single function at a time). The mx and the 6060 were arguably a touch heavier built, I think the operating comfort was higher on the 6060 and comparable ish on the MX. The kubotas also had a lot more electronic gew gaws and blew out my budget a bit to much.
