FEL hydraulic problem

[WayneB]

I have a Kubota B-7500 and I have the quick hitch sub- frame for me angle snow plow and snowblower. I purchased a hydraulic motor that I want to use to rotate the blower chute.

When I tried using the Husco controller I found it would not rotate the motor in both directions when connected to the control output connectors used to curl /rotate the bucket.
When I connect the two hoses to the output fittings that lift and lower the FEL the motor runs fine in both directions

Looking at the two pictures the control box is mounted on the tractor and the two connectors on the right side ( looking at the picture) control the up and down motion of the FEL. When connected here the motor works properly. When connected to the two on the left side the motor only works in one direction. The controller is a Husco E02A0637-05. There is also another number series 7J044-61011 and 9210- B2C

Do you have regen in the first part of your valve.

I remember a problem having to do with regen using a hyd motor..

Wayne, do a search for the term "regen" and my name, you will find LOTS of reading on this subject.

In short, for your Kubota try pushing the valve hard over to the left...

During regeneration there is no flow to tank.

The trick is to slip past regen.

The "Regen" only works in 1 direction - dump. So if going into Regen and equalizing pressure on both sides of the motor is the problem, it should still work when he moves lever to roll-back, turning motor opposite direction.

Joystick loader valves if they have regen, is to the right. Some of these have the regen in the immediate right, and other valves have it in the far right.

Just don't go into regen, or go by regen fast to power mode.

JJ thanks for all of your advice regarding regen and hydraulics, it is certainly appreciated.

After several attempts and not finding the sweet spot to make the motor function properly I finally decided to forget the idea. I also have a weather break on the tractor and the control arm for the FEL hits up against the frame of the weather break which makes it difficult to manager.

So I have moved onto adding a dc motor to control the chute rotation and a linear actuator to operate the chute deflection.

Both seem to be doing just fine and the proof will be when we get our first heavy snow fall.
