Really liked your presentation, very thorough!. I also have a Kubota B7800. What interested me from the start is the plate you added to the bucket! I would like to know where you got that! Seems it would help in land clearing a bit more.
Also, your B7800 was a lot dirtier with 600 hrs compared to mine with 800 hrs! But, as you said, your always in muddy conditions. I like a “clean Machine”! Ha!
