Kubota L3400
I have a 2007 L3400 HST Kubota. 154hrs. I just started having problems with my steering and bucket. Trying to steer , but it’s not smooth, it’s difficult to turn. The bucket is very slow to rise, jerking motion. Even when empty.
The fluid is normal. Wondering what the problem is, the dealership thought it could be “lack of use “ maybe air in hydraulic lines. How can I check for air in lines. I see no leaks on hoses, thx David

You are getting inadequate flow and or pressure;
when was the filter or fluid changed last?
does that tractor have a suction strainer?
when was it last cleaned.
That would all be for flow for pressure a gauge would need to be plugged in a remote or tee'd into a line.

Hey, thx for the info, I changed the filter at 146hrs ( it’s now 154hrs) you mentioned a suction strainer? I have never changed it, where would it be located. Thx David
