Kubota B3030

[Rolf]

Morning all

Can anyone help out with this ?

my Kubota B3030s compact tractor 3 point linkage position control has begun to make a hissing noise ( pressure relief )

when the leaver is in the up position. Also it’s sensitivity seems to be compromised. 

I recently serviced all filters and changed the oil but sadly it’s no better.

its the hydrostatic transmission if that helps.

Thanks in advance.

I had similar on an old b1700 I discovered if the lift lever was all the way up, it tried to keep pumping oil, I just had to put the lever down a touch, that stopped the problem

When you did that adjustment did your position control work as it should?

Mine is not, all sensitivity has gone and it work like a switch. Up or down.

Yes it did. Are you saying yours is either fully up, or fully down, and you cannot choose any point in between?

[Rolf]

Yes pretty much. You can achieve position but not without carefully setting of the lever.

you used to be able to set it anywhere and no blow off at in the highest position.

Mmm. Best ask the dealer. That's a new one on me
