Wondering what people are using for engine oil. I’ve found 10w30 diesel and 15w40 diesel. Manual lists 30w, 20w, 10w (or 10w30) depending on temperature.
B6000 Engine Oil

I have been running dexos 2(GM) motor oil 5w30 as I try to only have a half dozen of different grades of oil. Just make sure the oil is rated for diesel engines. Diesel engine oil has different properties than gasoline oil. The 15W-40 "diesel" oil wins in a lot of things: It will have stouter base stocks. HTHS Viscosity is pretty much guaranteed to be higher ( viscosity at 300F ) They pretty much always have hig levels of ZDDP which is an additive used to prevent camshaft wear on old flat tappet engines. It will probably have a Higher Total Base Number, which is the oil's ability to fight off acids. It will probably have more detergents and dispersants which will keep the engine clean. They require less Viscosity index improvers, which means the oil will maintain its viscosity for longer, and also VIIs create deposits when destroyed and form deposits inside the engine. It will probably even be cheaper than a 10W-40 Passenger car oil! Keep in mind oil companies have in mind that a 15W-40 HDEO will be used in equipment that is worth sometimes hundreds of thousands of dollars, they cannot afford to have an engine failure caused by one of their oils, so they put a lot of effort into designing these oils.

(15W-40 is suitable for most ambient temperature ranges, which is why it is so popular…
check with your Kubota dealer…to see what they carry for customers…. and you’ll likely find their Kubota oil is: (but use any brand you like)
My manual gives several options. One of them is 15W-40. I've used it year 'round for several years with no problems. Of course you do want diesel rated oil of whatever viscosity you choose.
