I just bought a tractor of that size. (3 series) I previously had a John Deere, but knew I didn't want to spend that much money again, but I did shop them too. After I'd shopped all the others so I would have a good comparison.
I thought I'd probably end up with a Kubota so I began there. They had some financing deals and were going to "throw in" a box blade too.
I forgot to say that I spend months looking at used ones of all brands and they were so expensive that I thought I might as well buy new and get a warranty and not have to worry about previous wear.
I seriously shopped Kioti, JD, New Holland, LS, & Mahindra, but I also looked at several others and dismissed them out of hand due to price, quality or just the fact they were unknown and so I worried about service.
What is the business end of the tractor going to be for you? The blade ended up becoming a very big bone of contention. The John Deere had a special proprietary attachment system and a very strong blade.
Most of the others used skid steer attachment points for their attachments which meant the world was your oyster as it meant you had lots of options and possibly some better pricing options (I've since found several used skid steer attachment places that will save me money on several other attachments such as a fork lift front end for $400 rather than $1,200)
The surprise weak brand was Kubota. Their blades were so weak that I found almost half the blades were bent in shipping or in assembly which made me worry about what else might be substandard.
Long story short I ended up with the LS brand. It seems almost all are Chinese or Korean, even the John Deere. And when I saw a picture of the LS and the New Holland (which was much more expensive) coming off the same line and the only difference was the branding & possibly the front hydraulics that's where I landed.
I got better front hydraulics and skid steer heavy duty bucket, a box blade and a 25 hp (above 25 hp demands a very expensive particulate filter system that costs between $1,000 - $2,000 periodically) all for $17,000.
Financing was 2%. I had originally thought I'd pay cash for a used one figuring I could buy one for $10k or less but many of the used ones were more expensive than the new ones.
Oh, make sure you get one that takes 5' attachments and not 4'. Lot's of 5'options but fewer and weaker 4' options
