I have a 1985 Kubota G4200 H, it is a fuel sippin 2 cyl diesel. It came with nothing, learned in New England there isn't much used Kubota attachments for it, BUT I am holding out hope that I can use the Hydrostatic transmission to get a hydraulic lift for a custom 3 point hitch assembly and run some ground engagement attachments, skid some logs, make the most of this tractor...

When I posted on Google, How can I run hydraulics from a Hydrostatic transmission?

It brought me to this forum, there was 5 pages of posts and back and forth between members on this subject, nothing that answered my question though, and most of it was dated and not specific to my Kubota....

So refresh on the question, is it possible for me to get some "live" hydraulics from from tractor, and of so how?

 

FYI so far I added a custom exhaust as the Kubota dealer wanted $180 for stock. Mine cost me $60, $35 for the muffler and $25 for a custom flange. Savings priceless! Then the fuel pump went...again $100+ from the dealer and I got a 12V universal on Ebay for $16...my engine doesn't know any better....

Looking for practical, utilitarian advice, on what I know to be a complex subject.

Mike, Welcome to GTtalk, glad you found us.

 

There will be a few guys come by in a little to answer your question. I'm not up on what Hydro the Kubota uses, but I'm sure like most all the other makes, there is a port to pick up live hydraulics off of.

Welcome to GTt,

I looked up the tractor spec's and couldn't fine what I really needed. But with that said, I think you may get a little out of it but not much. If you could get much out of it I'm sure the factory would have done it when new. If you don't plan on using a deck for grass cutting, I'm thinking may be better to just add a hyd. pump and run it off the tractor PTO, plenty of power that way.

 

P.S. If you get sick of that tractor and it needs a good home let me know, :D

P.S.S. What part of MA?

I think so .... but i am Not sure it all deppends on the Hydro (i think its a eaton 11) but you would have to conferm that your hydro is a 11 how ever the pressure is only 500-800 psi i added hydraulics on my bolens 1256D diesel project ...

And welcome to Gt talk

Best of luck

:welcome:

 

I don't think that it has an Eaton 11 with only 12 hp on tap. At that level, most hydros did not have onboard hydraulics available short of a complete added auxilliary.system.

 

I added such a system to a MF12H 35 years ago using a GM power steering pump and cylinder and a spool valve set. The pump should be inexpensive, but cylinders and valves can run a bill or two, and hoses can be surprisingly pricey.

 

You might have some luck on ebay or CL, once you know what parameters you want to deal with.

 I never saw an Eaton 11 on a Kubota in my life. All that I have seen had the diesels driving a right angled gear box to a vertical shafted hydro tranny llike the box store stuff... These looked to be a bit heavier ,but not much... and were not really designed for ground engaging attachments. So I don't think it may be possible to tap off your hydro tranny. Your best bet would be a 12 volt pump unit like WheelHorse/Toro used on there 263 series tractors .

Welcome to GTTalk !  Can't help you much except if hyd of your hydro won't work maybe a 12volt linear actuator for the rear lift ?

Welcome to gTTalk. The hitch in your photo uses an electric actuator to lift. That may be a reasonable choice for you as it is much easier to implement than tapping into the hydraulics and adding control valves if that is even possible. You may want to do a bit more research into the limitations of the transmission and what that means for your plans to use ground engaging attachments.

Welcome to GTTalk! 

 

I agree with those who said put a hydraulic pump on the PTO.  Garden hydrostatic pump/drive systems aren't really equipped with a large enough reservoir to handle other uses.  However, I may be wrong.

Also there is a spot to mount a hydraulic pump to the engine ....

I did a bit of Google searching, and it appears that the G4200  did have a CAT 0 3-pt as an option.
