3000-4000 series loader operation

[MessickFarmEqu]

What does that mean???? JD can't build a cut loader that does multifunctions in real time(not slowing to a crawl)?? Or they want to use cheap inferior parts to shortcut this operation??? WHich one is it?

There must be somthing to this, because its been showing up in some of the competitive comparison information that I get. The fact that this is a weakness is being promoted.

At some point, it would be nice if you actually knew what you were talking about before you made derogatory comments about JD equipment. But, I suppose that would just be too much to expect.

There is a 3 position lever on open station tractors, and a lock lever on cab tractors that control the operation of the SCV. If you have the SCV "unlocked" it will move in all directions and you can blend the motions. If you have it in the "regen" position, this will increase the dump speed of the bucket. See pages 36 and 37 of the Operator's Manual.

With my open station 3320, and the lever set to the "C" position (SCV unlocked, with "regen") - I have no problem with 300CX loader lifting and curling, or lowering and dumping simultaneously.

Neither the speed of the tractor nor the speed of the hydraulic system slows when using simultaneous multiple functions.

I just moved 28 tons of 4-inch and minus rock in 3.5 hours, placing it in a 6-to-8 inch thick layer 6-feet wide around an arroyo. Believe me I used multi-functions to lift and curl to load, and simultaneously lower, dump, and backup to spread it.

However, you do have to get used to the operation of the control lever. On my previous tractor, blending functions was easier. The Deere lever seems to be picky about the position it needs to be in to get the simultaneous functions. When I first started working with the new tractor, I could not seem to get multi-functions, but once you work with it for awhile, and get the feel of the lever / valve operation it becomes quite easy.

Due to the info above:

Open Station

Selective Control Valve (SCV) lock lever (A) allows the operator to control the type of dual SCV lever movement needed for a particular operation or situation. Operation of the lock lever is indicated on label (B).

To allow movement of dual SCV lever in all directions, move lock lever to the top position (C). Operation of the dual SCV is totally unlocked.

To prohibit engagement of the regen (regeneration) function of the dual SCV, move lock lever to the middle position (D). This position is recommended for all implements except for the front loader. Heavily-loaded loader buckets will dump more rapidly when the regen function is engaged. The regen function is available only with the lock lever in position C.

To prohibit movement of dual SCV lever in all directions, move lock lever to the bottom position (E). Operation of the dual SCV is totally locked.



Cabs

Selective Control Valve (SCV) lock lever (A) allows the operator to control the type of dual SCV lever movement needed for a particular operation or situation. Operation of the lock lever is indicated on label (B).

To allow movement of dual SCV lever in all directions, push the lock lever inward to center position (D). Operation of the dual SCV is totally unlocked.

To prohibit engagement of the regen (regeneration) function of the dual SCV, push the lock lever all the way inward (F). This position is recommended for all implements except for the front loader. Heavily-loaded loader buckets will dump more rapidly when the regen function is engaged.

To prohibit movement of dual SCV lever in all directions, make sure SCV lever (E) is in center position, and pull the lock lever straight outward (C). Operation of the dual SCV is totally locked.

I am willing to pay extra for this capability!!!!

Its free!!!!

Now we know why some do it and some don't..... I always wondered what that lever did...

same here mine and mine is set-up so that it unlocked with REGEN mode "C".

What is scary is that apparently a few of the dealers that pbt_sisson went to may not have explained this configuration Or did not know how to do it? sort of if you get a large Ag tractor specialist instead of the CUT specialist and vice versa at some dealerships, maybe?

Nuru:
I am very familiar with the loader control lock//We tried several tractors and moved this lock into all 3 positioins. THe 1st setting locked the joystick fully//no movement. the 2nd went to normal 12,3,6,9 functions. the 3rd didn't make much difference from the 2nd. The loaders still wouldn't blend. Only a few would move together, and then only at a snail's pace. And yes we had the engines revved up///at 2000+ and 2500 rpms, pto speed....no change.
Is it possible that these loader control valves are bad???or misadjusted?/Remember, I have demoed 3 and run 20+ at these va dealers. None blend at real time speed

The SCV lever makes no difference on my 3320 with respect to the blending issue.

It's obvious after reading 57 posts on this string, despite what experienced owners have reported - you willl never be happy with JD FEL operation.

Move on - if the Kubota is so wonderful - buy it.

Swines - All due respect, but the SCV has also been beaten to death, "C" position is not a miracle cure for lack of true blending. And yes, they will blend, if the moon and stars align, and then only slowly. True blending as offered by most manufacturers is intuitive, easy, and fast, nothing like the awkward/slow version offered on the open station 3X20 series.

FYI - the open station valve is non-adjustable, there may be manufacturing differences at play allowing some valves better blending capability, still nothing to write home about.

Cinder - "Move on", that's extremley helpful to us loyal JD owners stuck with inferior valves... How about JD actually adressing this issue, instead of avoiding it??

The Regen function on the valve has NOTHING to do with "blending". It's a function of the valve that helps keep the cylinders from cavitating when dumping heavy loads. As the manual page stated...it should only be used when the FEL is mounted. If you mounted a plow or snowblower-it MUST be locked out for proper operation.
