BH77

[Rogan]

Hey I have a BH77 on a B2650 . I have had a lot of trouble with the backhoe - main boom lowers to the ground on its own while operating , not swinging properly side to side , with tractor running the main boom will not stay up . Kubota has replaced relief valves , main control valve bank , and it still continues to act up .
Looking for your thoughts thanks

Sounds like the boom cylinder may be the problem. if you raise the boom and turn the tractor off and let it sit, does the boom stay up, or relatively quickly fall to the ground?

Are you SURE they replaced the control valve? Rather than trying a repair that may not have fixed it?

What do you mean when you say "not swinging side to side"? Boom should stay up whether swinging side to side or not.

How many hours on your B2650?
Is it still under warranty?
