3320 FEL Bucket Question

[cartod]

When I tilt the bucket back, should it maintain the back position or do they tend to move toward the dump position with a load? Thanks

It should maintain position while the engine is running and the control lever is in the neutral position.
It will dump faster when the control is moved toward the dump position. The heavier the load is: the faster it will dump.

This is a popular subject, been discussed several times before, but it appears that even when running the hydraulics will bleed off. Seems that JD even thinks that is acceptable.

First hand experience with my 2520 proves that it will tip on its own, eventually.

The bucket should maintain its position. With the bucket empty push the joystick all the way to right, so as to put it in regen/fast dump and allow the bucket to go to its lowest position, would not hurt to do this twice.

If this does not resolve your problem reset the quick disconnects.

The following was taken from another post on what Regen is.

Regen is a "feature" of most modern FEL (Front End Loader) valves, it's on the Dump (joystick far right) circuit, and is also referred to as "Fast Dump". The reason it is nice to have is that without it, the weight of a filled bucket can actually "pull" the bucket down faster than the fluid can enter the other side of the cylinder, this will create a air pocket and give the bucket a "floppy" feeling until the joystick is held in the dump mode a few seconds to refill the cylinder pushing the air past the seals. So we add "regen" or "regenerative" function to the valve.

Regen solves this problem by actually filling both sides of the cylinder at the same time with hydraulic fluid. But how will that work you might ask? Well, because there is more volume on the side of the cylinder that extends it since the rod is taking up space in the other side, it "overpowers" the rod side and lets the cylinder extend-thereby dumping the bucket. So since now both sides of the cylinder are "pressurized", the air pocket cannot develop, eliminating the "floppy" bucket syndrome. One other added bonus is that the bucket actually dumps faster due to the higher flow rate required to do all this, that's why it's referred to as "fast dump" sometimes.

If I understand you, the problem is in the curled up position, and a loaded bucket should hold that position. However, there can be some leakage in the valves or in the cylinders that will allow the bucket to drift down.

There is a tolerance that is considered acceptable before repair or replacement is considered as a fix.

As I am reading this, your problem doesn't include the regen feature. But it may contribute to some of the drift you experience wanting to maintain the 'back' position.

 

[JD5210]

The reason I explained what regen is/does was to aid in understanding why pushing the joystick all the way to the right would possibly correct the problem.

I was not trying to indicate that regen would be the cause of the problem.

Sorry if I confused the what the problem is.

So, what would make the bucket slowly tilt to the dump position. This is a brand new 3320 with no leaks in hydraulics.

I have the 3320 and the bucket will drift to dump, so I keep tilting it back as I drive. Habit for me now, but wish it would hold.

 

[cartod]

So a drifting bucket on a brand new 3320 is something I should just live with? I really hate the bucket doing this.

For instance if I get off tractor to load bricks in bucket, I have to keep walking back to joystick to tilt bucket or the brick will fall out.

Well you could set it on the ground.

The FEL on my 2006 3320 does not drift down. Not the lift, not the curl. Perhaps after hours it may drift some, but I never notice it. Engine off or on matters not. I have stood in the bucket for hours lifted at high as it could go to install new windows in the house (OK I know I should not do this), with out any tilt at all. About the only time this bothered me is when the dog decided he too wanted to get in the bucket. He jumped up into the operators station and I knew for certain he was gonna hit the control lever and dump me and my son out. He didn't ...

i think your misunderstood buddy. Even if you set it on the ground, it will still tilt forward and the guys bricks will dump out. I know this from experience with a jobsite loader that has same issue.

 

[arlen4720]

Deere has a published acceptable leakdown rate. You can look at it on the "other forum".
For your setup it looks to be 2 or 3 inches per hour.
My 400cx on my 4720 leaks down a few inches overnight, MAYBE.
If you are talking inches in minutes, VS inches in hours, you have a problem. Maybe a bad spool valve.
The dealer will fix it.

 

[Pushing_Tin]

Mine does not have this problem.

 

[charleyfarmall]

Mine always drifted forward. I go used to it and stopped worrying about it.

Your bucket should not drop that fast. For a new tractor, I'd be at the Deere dealership for warranty repair.

 

[sfloggie]

I agree about warranty work if is new. However; I have a 2006 3320 and drifts fast. I tilt it back automately as others noted.

JD Dealer service came out and packed it on the trailer. Said its not acceptable for it to leak off like this. He tested it by lifting front tires off the ground with fel. Since it leaks off in both directions They ordered new spool. Hope this is the fix.

I was being something that annoys me on here. So my bad for acting that way.

 

[jack43]

something to think about. The warranty on the fel is only one year as the tractor is 3 years. jack
