Understanding Kubota L305DT Hydraulics!?

OrangeMan7 · Mar 14, 2012

3 Point, once up jerks at the top continuously...And the Loader acts odd at all times, not lifting sometimes, and when 3pt is in motion, doesn't respond correctly...When pushing to bring bucket down, it goes up. Once the 3pt stops at the top or bottom with nothing hooked up (no jerking then), the loader will operate properly. This one has me puzzled. Any help here is greatly appreciated!:thumbsup:

There are several people that have complained about the loader and 3pt troubles.

One solution is to not use both 3pt and FEL at the same time.

Apparently the 3pt is having some affect on the FEL controls.

I can see where if the 3pt is operating at the top of it's travel, the pressure is being relieved, and there is back pressure all the way to the pump including the FEL valve. The FEL valve might also be trying to relieve if the cyls are maxed out. .

So far, no one has explained what is happening when this occurs, except to note that the 3pt is interfering with the FEL hyd circuits.

Someone with a hyd gage and flow meter might be able to answer or research this problem.
