Kubota L3901 HST Low Preasure for Auxilary Hydraulics

[wahlmeie]

Hi,
New here. First Time Post.
I have a 2016 Kubota L3901HST which has 1 auxiliary hydraulic attachment (dealer installed) that runs to the front of my loader to power attachments like my danuser post hole digger and danuser T3 post pounder.
While using it this weekend I noticed that I was not getting much flow to my attachments and the problem just kept getting worse until my attachments became unusable.
My loader functions fine and my HST is running well.
The problem only appears to be with the auxiliary hydraulics.

Any ideas how I should diagnose this issue further?

Thanks!

I didn't think that you could effectively run those off the front. The attachments you listed require high-flow (as in skid steer) i thought.

Hi dirtydeed,

I had conversations with both Danuser and the Kubtoa Dealer before I purchased.

Kubota is suppose to out put 2347 psi Pump flow: 6.3 gpm

The Danuser T3 can handled 1500-3000 PSI & "Up to" 30 GPM*
Works well with the 6.3 GPM that the kubota usually provides, just longer time between strikes.

The Danuser EP6 can run with 6 - 15 GPM up to 3000 PSI and works well.

Please also note that I have been using these attachments of over a year now. I have been building small vineyards. I mainly use re claimed oil pipe and t-posts from my trellis. So lots of digging and a lot of pounding...

Thanks
