Hi gents, I am parting out a kubota b2910,I believe a lot of the stuff will work on a b7800 and also a 2710. I used some parts of this tractor to build up the one that I had pulled out of a barn that caught on fire. The motor ran just fine, and I have quite a few parts left over. If you are interested please feel free to email me and I would be happy to answer any of your questions. My email address is jeepin60@aol.com thank a bunch. Nic
