Hi Kubota BX owners. I have a 2006-vintage BX1850 and live in western Massachusetts. My BX is stored in a covered overhang alongside my horse trailer; protected from precipitation but exposed to wind/cold. Our winters routinely drop into the single digits and I've had issues with winter starting and battery life. I rigged my battery with a permanent battery maintainer connection and selected the NOCO Genius 5 as my charger/maintainer (based mostly on comments from the OTT forums). Well; no disappointment here. It does the job without issue. I leave it plugged in and the battery is exercised and ready-to-go always. I'm mainly impressed with the build-quality of the unit. Very compact, tightly sealed, and can take a hit. I've attached the small unit to my rollover bar and there it stays. Simply make your disconnects and start 'er up. I'd have no reservations about recommending this $90.00 product to other BX owners. If I have a negative, it's the quality of the wire connections between the main feed and the terminal clamps. These could be improved. Good luck.
