Backhoe SAMUL TIME EOUSLY..... NOT ON MY KIOTI

[ron45]

I recently got a Kioti KB2376 operators manual from ebay. It's a 2004 edition. I has parts numbers and exploded views for many of the components. Near the end of the operating instructions for the B H, is says, boom and swing control levers and bucket and crowd levers can all move simultaneously. I'd seen other tractors do this but not mine. what are some of the things that can be preventing that behavior?

I should note that I often work in the 1400 to 1800 rpm area. The controls are quite jerky at higher RPMs. I'm usually scratching up surface rock on our access road. For heavier work it has to be up there at 1800 or so. I do have several small leaks I see wet places on the metal but little if any fluid on the ground where I'm working. I do watch for that.

So to be clear I understand the above claims to mean I should be able to swing the boom around and extend the arm or move the bucket simultaneously?

Even with the small amount of seat time I have this sounds expensive. What are some things to ckeck please. Is there a place to get pressure readings for the hydraulic system. Also the sight glass, a gross exageration if you ask me, but there is a little white X or cross thingy in the view port, all I ever see there is a bubble occasionaly or the white cross thing. `Sure be nice if it moved to let you know fluid is moving in the system. If I see the small bubble I add a little fluid. I haven't changed the oil filter for this system now that I think about it. But I don't see how there could much dirt in the fluid and not see evidence of it in that nanowindow or when I take out the fill plug. It always looks very clean in there. Thanks for your time

I have a 3pt backhoe on my Kubota and if I pull the lever all the way, some have priority and only one cylinder moves at once. If I am careful (not tired), I have more finesse and can "feather" and get some smooth motion from two at once. I suspect if I had more backhoe hours, I would be a better backhoe operator, but no guarantees.

... and a humorous video it would make if I ran at full throttle when I am tired. The lever that is pulled but not responding will respond abruptly when the first one is done... sometimes I get motion that I did not expect.. I have to try and just use one hand at a time when tired... enough said.

Hawkeye hit the nail on the head. My KB2375 works the same as his. The only way to get all the functions working together is to only have minimal lever inputs so each function can get enough hydraulic flow. The jerkyness could be your need more seat time because the controls need feathered when moved. They respond fast to a little movement and nothing like when I ran a mini track excavator. Even though you don't see dirt in the fluid the filter could still be getting plugged a little because it's doing it's job well. If you don't know how many hours on the filter, I'd probably change it.
