Kubota Hydraulics question

[Living Rural]

Hope somebody can explain what is happening

I had borrowed a DuraTech Haybuster 77 from the local soil conservation district to drill some fescue and orchard grass. I have Kubota 3010 without a rear power takeoff. So my plan was to run the haybuster hydraulics from my bucket hydraulics just like I do with my log splitter. I use the two hose connections that tilt the bucket, not the ones to lift the bucket. I was expecting that the controls to tilt the bucket, would raise and lower the drill.

The bucket tilt control did not work as I expected, what I found was that the controls would work in one direction only. I could either raise the seed drill or lower it. If it needed to go in the other direction, I had to reverse the hydraulic cables. I got the seeding done, but it was much more painful than it should have been. Can somebody please explain to me what was happening, and perhaps a better way to do this in the future?

thanks

Sorry! I can't help you out! I'm never drilled fescue and orchard grass or any grass for that matter! Always seeded it.

If you are using Single action cyl , then using the curl circuit may give you trouble because of the regen part of the loader valve.

Other people that have tried to use the regen type valve with snow blade to angle have had problems.

If the machine only has on SA cyl, then a single spool valve with PB and cap off one of the work ports would work. If it is a DA cyl, it should work correctly.

Thanks for the feedback, based on the responses I gave my local Kubota dealer a call and talked to the service manager. It seems that the bucket curl ports have regen (confirming J_J's theory) which keeps pressure on both sides. The bucket lift and lower does not have regen and he tells me I would not have the same problem with those ports.
