Kubota B7800 Power steering problem?

[ozarkbru]

Don't mean to hijack your thread but this might help as well. On my B7800 you can turn it easily with one finger low tire pressure and bucket loaded.
I changed my filters last summer and had a tough time bleeding the air out of the Power steering but finely lifting the front end up with the bucket and turning the wheels to the left and right it started working correctly. Now in this freezing weather I have to do this every time if I want to move it before the tractor gets good and warm. When it's not working it is almost impossible to turn.

Just read in another post this could be caused by a hydraulic filter sucking air, Hmmm, those things should be changed at 50 hours too.

The hydraulic filter on my b2710 should be changed every 300 hours according to the manual. I just changed it and the fluid, and with the tough economic times presently i just couldn't afford to use kubota fluids. I got a five gallon bucket of Warren Tractor oil for $29, and five quarts of 90w gear oil for $25. She seems to be moving around real nice, especially the steering and the FEL. Peace to all!!

With better air pressure in the front it seems somewhat better. Almost effortless between 10-2 O'clock positions, but it gets more difficult as turn further out to the extremes. Could this be an air issue? Tractor only has 120 hrs. fluids are all ok as far as I can tell. Thanks for all the replies. ANy way to get a "complaint" on file with Kubota now (since my warantee runs out in a few weeks) and then continue to diagnose the problem with their techs?
