I have a 900RTV Kubota diesel. Probably 12 years old. Only problem I have with it is when the grandsons come in and say,"Papaw. we need your 4wd diesel truck to tow the Kubota out of the stock tank". How did that happen, "We don't know Papaw, we just turned our head while fishing. The next we knew it was in the water". OF COURSE! I was born yesterday and couldn't understand! I'm regular on oil and all the filter changes along with the hydraulic fluid and filter. It has a dump bed, 4wd, and 4 wheel diff lock. It also has hydraulic lines with disconnect to operate other tools. It ain't fast and rides rough, but it serves our purpose. I have replaced the rear tires.
