Steering feels a little jerky

[Kenneth in Texas]

when sitting still idling at normal rpm, turning the steering wheel left or right I can feel and even see in the tires a little jerkiness instead of the smooth steering feel it has always had. Fluids are good, no leaks from any front end area. Just started this yesterday, not real bad BUT bad enough for me to notice it and not like it. Any ideas what to look for?

I would say use the steering brakes, but Kubota never figured those out(insert hahahahaha here) My old Kubota had Armstorng steering(fwiw, I still see old tractor even 5 years later; B8200 is still going strong!).

Have you checked color of fluid against new fluid? Maybe it is getting old, possibly contaminated. Fluid is cheap, might be worth draining and putting in new fluid. Cheap and easy starting point. What does manual say for PS fluid change interval?

Are the screen and radiator fins clean? The B7500 I had acted like that when the hydro fluid got hot.

That was an occasional, and annoying, feature of my 1999 B2710. Mine was a early one with a single hydraulic fluid filter. The later ones came with 2 hydraulic fluid filters.

Check your suction return hose under your R front foot pedal for leaks and or cracks . Pretty common to L2800/L3400 Botas.

thanks for the replies, when i get back home i will check those things but the fluids were changed 3 months ago and have only done 30 or so hours since then. Far as that hose you are talking about that large one that looks more like a tube by my right foot correct?

YES !

The suction hose is a known problem. Pinch it and look for cracks. It sucks air into the hydraulic pump.

Carefully looked over that hose/tube, looks as good as the day I bought the tractor, no cracks, no splits, no nothing, however did notice that my hydraulic oil filter has a small dent in it, not a large one but a dent nevertheless, wonder if that could be it? Or any other ideas why my steering has suddenly become jerky while sitting still? Seem fine while there is forward motion.

You did say at idle. Could your idle setting be too low? check that as at low RPMs the flow is minimal and on some pumps you actually feel the pulsations.
