I love mine. It's used every day on a vegetable farm and has held up well after 130 hours or so. It sips fuel and that's my favorite aspect. Not particularly fast, but will get up to 28/29 if you have a few hundred yards of straightaway. going around the 20 to 21 mph range at top speed will be the norm. I do use it during hunting season and it has performed really well, but I am not asking of it something it's not designed for. It resembles a small tractor much more than a regular UTV. It weighs around 800lbs more than the comparable polaris and it doesn't have the engine or transmission to spin the tires in mud, so I don't go charging into places I feel I can't make it out. It will go through shallow creeks, etc, but not go into a huge youtube worthy mudhole and expect to come out. Ultimately it was designed and built for work in mind, and th
The real value in the kubota rtv-x is the fuel savings, the assurance that when you turn the key the thing will run, the assurance that you are buying a 15 year machine, at least, with maintenance, your buying a machine with "house made" components (ie a bulletproof kubota brand diesel engine, kubota brand hydrostatic transmission, both of which have been used in many applications OTHER than UTV's and are proven reliable, something no other company can claim) and it's a **** comfortable machine to ride in. You'll be able to go faster, go through more mud, and have more "fun" in competing UTV's. If your salesman at your local kubota place are honest they'll tell you the same thing, I know mine did: that if you aren't buying the machine to work and just for "play" your going to be really disappointed when you start measuring sticks with their buddies with polaris's, etc. But for what it's designed for you can't beat it.
Check the coolant level. If it's low then there may be a loose hose clamp somewhere from the radiator back to the thermostat on the engine. That's the only issue I had with mine (disappearing coolant) and it took my local dealer about an hour to figure it out.
50 hour service is a breeze. Just an engine oil change and change 3 filters (one for the engine, two for the hydraulics). Hardest part is bolting the skid plate back on (have a way to jack the plate up for easier bolting on).
