I currently have a 2wd MX4700, but I have found a 4wd MX4800 that I could possibly get. I'm new to Kubotas in general, and especially any tractor with the Regen on it. Would the MX4800 be be a better overall tractor even with the regen? I know the 4wd would be an upgrade. Both tractors have around 700 hours, and both have FEL. Is the regen really that troublesome, or has that been exaggerated? Thanks for any suggestions or input.
