    B7800 with LA402 Loader Control Valve Problems

    That is why I picked up the tractor. They had something else new they wanted to try ever time I went it. They hardly ever called I had to stop by to catch someone to talk to about it. Worst part is they sell Kubota products at several of their locations. Never again will I take anything there. I...

    B7800 with LA402 Loader Control Valve Problems

    I have posted a few months back on this problem. Problem - control valve that came on equipment had issues where it was very jerky and would freeze up in winter. I had a mechanic work on it and he thawed it out and drilled holes in caps on bottom of spools. But the damage was done, still jerky...

    B7800 Wix or Fram filter numbers for oil and hydraulic filters.

    I have a B7800 and like to change fluids and filters regularly. But the cost of Kubota filters and fluids are expensive. Has anyone ever used Wix or Fram filters and if so do you have the comparable numbers? I have used a Wix 51334 oil filter without a problem. I had found that a Wix 51551 is...

    I have a 2004 B7800HSD that I bought new back in 2004. I bought it with a LA402 loader, a Woods 7200 finish mower, a Woods 7500 backhoe and recently won a Mow King TAS-81 rototiller on ebay. I know I'm pushing the limits of my tractor with the rototiller.

    3 POINT HITCH INOP

    I have been following this thread because I am having the same problem with my 2004 B7800hst. Mine feels like something is broken or disconnected so I downloaded the parts breakdown for the tractor. Could we both be having a problem because the spring pin sheared off from hydraulic piston that...
