Don't mow lawn with a $20-40k tractor. Mow lawn with a $3-10k zero turn. It will go faster (about twice as fast as a normal garden tractor), your back will thank you, there will be little lawn repair needed and no ruts, and it will keep the hours off your expensive tractor. If you value your time at all, the time saved by using a much faster piece of equipment and not having to deal with the bullshit of donning and doffing the belly mower will pay for the zero turn in a few years. I've got 9 seasons and 700 hours on my zero turn with nothing other than a set of blades (Oregon G6) drive belt, deck belt, oil, and filter change every year... and once I replaced the filters and fluid in the wheel motors. I used to mow with different tractors, including one that went way faster than my zero turn, and it still took twice as long.
What are you going to do with it? To me, it is kind of pointless to have a tractor if it can't lift ~2k at the pins. Needs to have fast hydraulics so you can run a 3 point backhoe. So you're looking at a 30-40hp tractor. Otherwise, why spend $20-40k on a tractor when you can buy a 30 year old used one oldtimer bought when he was a middle-aged man to mow the lawn and till the garden for $5k? There are lots of suitable $5-10k 80s 2wd and 4wd tractors out there that are easy to work on. A lot of them just sit in the corner of a pole barn.
My cousin has two subcompact tractors, including a BX23S TLB that he mows the lawn with. It's the dumbest thing I ever saw to see a guy driving around with a TLB and a belly mower mowing the lawn. And he's got another tiny tractor, a Cub 6284D TLB, that just sits there because the Kubota is "prettier" (he has been saying he's going to sell it for years). They both can only lift about 1,000lbs at the pins and the loaders suck for digging so you pretty much have to use the backhoes. I have an old Bolens that can lift more, in fact, the limit is the weight on the tractor and I have loaded tires with 300lb lead wheel weights on it.
One of my friends has a Massey GC1725MB. Suffers from the same problem as my cousin's tiny BX23S TLB. Only can do about 1000lbs, FEL sucks but for whatever reason does better than my cousins BX23S for digging, backhoe only digs down 6' with what I call a trenching bucket, etc.
How much does the "dealer" actually matter to you? The kind of people that are on off-road forums tend to be handy. I doubt you buy your car because of the dealership experience. So why would you do the same for a tractor that at worst you can load onto a car hauler and take somewhere? I'd understand it more if it was a row crop or true utility tractor that you either need to drive there or have someone come and work on it. But we're talking tractors under 82" wide and 10,000lbs. So load it on a trailer. And how often are you planning on needing the dealer? Once every few years? I, personally, am going to buy a tractor I expect to never have to have the dealer look at after the warranty is up. Just like my cars.
So, I'm kind of a fan of Massey (AGCO) tractors. They tend to make their own stuff, but have other people's engines. You have to look at the particular model. There are good ones and bad ones and the whole line might have the same engine or not with different levels of "boost". Perkins, Shibaura, Mitsubishi, etc, you never know. Some of the "bigger" ones just have/had EGR instead of DEF by some magic. The Premium line of tractors is usually a better bargain. Oh, and the engines can change year to year. They sell an electronic manual of how to use diagnostics for like $40. In the compact to light industrial/light utility area you tend to get the most tractor for your dollar.
Deere is kind of a shitty company. They're the ones that were fighting to lock everyone out of their tractors (new ruling says Right to Repair is a thing again). They were very hard on this, until they realized they were losing a couple years ago. Now they have a shitty webpage saying they are happy to help, but most of the new old stuff still require a software update to open up the diagnostics through the menus. They're also the same company that always tries to buy a competitor and can't, they sue the shit out of them. They were trying to buy a seed planting company and the courts wouldn't allow the monopoly to be created so they waited until someone else bought the company then started suing the shit out of them. Deere's business practices make them a no-go for me. Plus most of Deere's equipment I'd buy is just Yanmar with green paint. When I was looking at zeroturns half the shit on them had MTD part numbers.
The only thing I don't like about Kubota is they're hard to work on, especially their smaller stuff, because everything is one engineered unit. But they don't break often so there is that. You can probably plan on it lasting with nothing but oil changes just fine until the 0% financing is complete.
Kioti... is like a Kubota as far as I'm concerned. I used to think they were sharing shit between them, and apparently they did, then there were lawsuits. If you look at them side by side they literally look like they share the same engineers. Kiotis aren't sufficiently cheaper than a Kubota to warrant getting a Kioti. It's like buying a Kia that costs 5% less than a Chevrolet. Why? If you ever need to sell it, nobody wants a used Kioti for the same reason no one wants a used Kia. They say you were too poor to buy a real car years ago and now you know it is going to Grant and Benjamin you to death on repairs.
I've spent a lot of time looking at LS. I want to like them... but get a Kubota.
New Holland still exists... but they aren't cheaper anymore. Might as well get a Massey, Deere, or Kubota. Most of their small stuff is rebadged anyway.
TYM makes stuff for a lot of other companies just like Yanmar but I haven't bothered looking at either of them. They seem to be the MTD of the subcompact/compact cheap tractor world. Only they aren't any cheaper than a Kioti.
