3000-4000 series loader operation

[Willl]

Of course it's going to slow down, your trying to fill 2X the cylinders at the same time.

THANK YOU JOMO....
Please don't respond to TRUE BLENDING" unless you have several hundred hours operating these things.
I think the os tractors and the cab tractors have the same loader valves. I sat on all of them.20+models. both cab and os. These new ones don't blend. And don't tell me the hydraulics will slow to a crawl because you are filling 2 cylinders......Go sit on any kubota, from the harry homeowner to the 100+hp machines. They all blend at true speed.
I would like to see a you tube video or something of NURU's new cab tractor blending. It would make a beleiver out of me and all the salesmen,owners,and mechanics at 3 different va dealers.

 

[Willl]

And don't tell me

BS, if your going to blend, it's gota fill twice as much as single action. Basic mechanics.

 

[JasonMac]

Hmmmm...... Like I've said many times before, mine blends! And when it blends it is smooth as silk!.... you would swear when I operate my loader that it was a Hydro Self-Leveling Loader... You just get very good at it after using them for so long. So I don't know... I guess I'll have to figure out how to put a video of it on youtube, so you can believe me.... sure it does slow down a hair, and when I say a hair, I mean very little... but it isn't jerky fast like I see other operators use their loaders....(including the operator on the JD Cab Tractor Promo Video -- you can just tell this guy is a novice at using a loader) that is actually a very bad video... loader looks jerky...but really it isn't if you learn to use it right....

Well I have a 2008 3520 with Deluxe CAB, mid-PTO, rear SCV, and blending apparently works well. I do not have Power beyond, nor an electonic diverter (Well I don't think I have this?). I would imagine that it works on the 3720 Cab tractor too.

Sorry Bro, I did not mean to offend you. I was rather trying to defend you as I beleive your statement since I have had a cab tractor do it on the lot.

 

[Nuru]

Oh, No, I was not offended by anything on the thread at all, I am just perplexed that the feature is not easy to use universally? That boggles the mind of me and some of the local dealers i have asked about it?

 

[Spudland_Dave]

Having driven tractors from 15-200 horse for the better part of my life and even an old Hough Payloader I'll say that my 3520 Standard Cab blends with no issues. Its no different then my my neighbors 3240....
Looking at JD Parts, Cabbed vs Non Cabbed have different Valve Banks:
Non-Cab: LVA15441
Cabbed: LVA15442
Like I said before...I noticed the difference after 3 minutes testing out tractors on dealer lots before I purchased...

Thanks Dave, I am gonna ask a couple dealers locally about this too. Cause I wonder what is going on with the difference between the two types of units. According to my tractor if you pull up on that stick, it allows you to perform the simultaneous operation of both and at 2000 rpm the movements are smooth and quick, if it slows down it is not much at all, it does not slow down to a crawl or at least that is what I remember.

Dave Spudland:
Thanks for the part #s. I will check on these. But all of the 20+ machines I have operated in VA have been cab models, and THEY DON"T BLEND>

Is it possible that JD put a cheaper open station loader valve on these cab units? Does the first loader valve part # not blend, and does the second part # blend? Are they interchangeable?

I have been trying to resolve this issue for weeks. I too have run equipment for years and know how this 300cx or 400x loader should work. The ones I have used don't, and the dealers are no help. THey say" it is what it is."

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?

I am willing to pay extra for this capability!!!! Maybe Dave, or NURU, I need to visit one of the dealers in your state. I just don't understand how the cuts at your states dealers will blend and the ones in VA won't.

A quick question or three:

• What RPM were you running when you tried it?
• Was it a deluxe cab or regular cab?
• Did it have the rear SCVs?

I spoke with Dealers I dealt with in the past in VA, and MA today and they indicated that, as per the Deere Literature the 300 series loaders and the 400 series loader do perform standard bucket/loader boom simultaneous operation. I asked them to find the instructions for this and to send them to me. when/If I get them, I will submit them to this thread. One of the dealers i called today indicated that there is a technique to get the unit into "Regen" mode and when it in that mode it wil blend is what I was told, and I was told that you can stumble into that mode? (Seems possible as that is what I did and dumped the bucket on the way up and cut-up some bushes on the way down). I also plan to call some other dealers in PA, CT, and MD. Also my unit was not on the lot, it was straight from the Deere Factory. Dunno if that means anything?

however don't get frustrated, as we will all figure it out soon. Hopefully those dealers help figure this one out.

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.

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?

 

[pbt_sisson]

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

 

[Killer_B]

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.

 

[Jomo45]

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??

 

[kennyd]

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.
