B1-16 Hydraulic Lift don't work properly.

[traktor.com.pl]

Hello everybody, I'm new member of this forum.
I have trouble with my B1-16, the hydraulic lift don't work. If I start the engine lift arms go up, ther is no reaction on lever control, flow control valve under the seat also dosen't give any reaction (I can't push the arm down). In this model is electric control level and solenoid valve, I nowhere can find diagram or value to check. Maybe some of member can help me? Please.

I have to admit that I have no idea what a B1-16 is but I doubt it has a electric control on it if it's a B series tractor. Has this problem always been there or is this a brand new problem? On all the tractors I have fooled with the knob between your legs in front of the seat will lock the arms in the up position or simply control how fast they will drop when you lower them. Can you give some more info about what this is?

Thanks a lot for interesting. The model is Kubota B1-16DT BULLTRA, on frame I have number starts from B1600DT...., of course I have knob between legs and it's work but only then when engine is stop (I can control speed of drop) but if start engine arms alone goes up. I try to make photos of solenoid valve (controling lift).

Check to see if the feedback rod is adjusted correctly. There is mostlikely a small threaded rod attached to the hitch arms. This rod is what tells the hitch valve to raise and when to shut off. Back the rod off the whole way and see if the hitch still raises. If this changes what is happening to your tractor, raise the hitch the whole way up and adjust this rod until you have about an inch of freeplay. To check this, grab the hitch arms and pull up, you should be able to move the arms up about one inch.

I haven't this type of regulation. In my Kubota B1-16 (B1600D) it is electronic. I attach photos with my solution. If you now how can I adjust this to proper work? If I tightened one of solenoi (this upper) then start to lift but in different weight on arms it's work not the same.

Hello,

I am from Germany and have a Bulltra B1-15. My one is with a Monromatic to control the lift.
But if you have a simple electronic regulation, you schould check the resistor of the Potentiometer. Maybe it's not variable anymor and gives back a fixed value.

Have you any Manuals? Maybe I can help!

And by the way, the translation software for german on your shop-page is not good. A wood-chipper is not a helicopter, and so on.
If you like, I can have a look over it to make it a little bit more professional...

Hello thanks for all hint.
Carl thank you for your links (photos were very helpfull to verification my system).
I check resistance in first, it' look good (it is range beetwen 0 - 5 kOhm) at two potentiometer. I check all the electric components and they are rather good, but arms dont work. I havent any manual (with this electronic) and I dont know how check electric valves. Have you any idea where can I buy this valves? (they havent any mark or name).
For example the Lower Right Switch = Monro Angle Adjustment
works ok.
Carl, thanks for your sugestion about our shop-page - actualy it was a Google-translation - I dont know German at all, I dont want take yours time but if you can look at this text it will be splendidly.

hello,

befor you start to replace something, have you checked that the Selonoids (the coils of th hydraulic relay) get power?

Translating can be done in the next day's...

Have you checked www.Kubotabooks.com? Look for 1502 or 1600, they are nearly the same.

Hello, i have some problems with my hydraulic Bulltra B1-17 too .
Yesterday my hydraulic starts to make some problems. if i let it down and i switch the lower left switch in the mittle position (there is no function or i disconect the valve) the hydraulic lifts slowly up to the highest position. Is the valve damage or is ther any sealing ring damage???

Thanks for you help! carsten

And yesterday i make some test and i found that my valve is damage where can i order a new valve with all parts inkl. but not the elektrical parts they are all ok.

Thanks for you help! carsten
