If you want a loader, don't buy a tractor without it. Used loaders to fit a specific model are scarce.
Exactly. Buying a used unit without a loader, expecially a Kubota is asking for grief. Kubota mates their loaders to specific models, always has.
The last new Kubota I owned was a 5030 HTC cab tractor. Bought it new with 2 sets of remotes, R4 tires cab and all options. I was just getting into hay making and while the 5030 was cabable of running my 1020 John Deere sickle bar mower conditioner, it lacked the power to (at the time) run my NH round bailer (long since gone as well as the Moco. It would struggle to run a full bale so I knew I was gonna have to buy something larger. Hence the M9000's I presently own. Bought my M9000 HTCC3 new and my M9000 HTC used a few years later and of course both have Kubota loaders.
Getting back to the 5030... I added cast center weights to it and I had to modify the ac a bit as stock, the ac was incapable of keeping the cab cool on hit days. The 5030 IMO has a bullet proof engine though it's not turbocharged. Far as the paint is concerned, all Kubota tractors fade to Mary Kay pink, including the 2 I now own. Interestingly, the structural fiberglass fenders on both M9's are fading at a different rate (shade) as the hood.
If I was to buy another tractor for utility use around the farm, I would not hesitate to buy a used, well cared for 5030. They aren't capable of running serious hay tools (they will operated a square bailer no issue), but that is it.
Why I jumped up to the M9 and I special ordered it with the creep gears and all available options. The M9000's are the last Kubota tractors to be built without emissions controls and I'll leep the 2 I own until I no loger require any tractors.
I was very lucky to find a used M9000 in good shape 500 miles from here and I snapped it up immediately, sight unseen.
It's not a cab tractor but had 3 sets of remotes and low hours. I put a couple grand into it in necessary repairs plus I had my dealer go through it. It's not going anywhere, neither is my cab M9000. I would never buy an emission compliant tractor anyway and today, in my required power range, they are alll emissions compliant and electronically controlled.
If you can buy a used 5030 for a fair price, I suggest buying it. It lacks the power to run serious hay tools but for everything else, it's a dam fine unit.
