3000-4000 series loader operation

[CinderSchnauzer]

After reading all the posts on this, I decided to see if the function worked on my open station 3320 with 300cx. So far I have not done much FEL work and what I did was usually at 1500 rpm's or so.

At 1500 the lift / dump and or lift / curl seem to work - but very slowly compared to single function movement.

At 2000 and above the lift / dump seems to work at what I would describe as reasonable speed. Lift / curl also seems to work.

FWIW, there seems to be a "sweet spot" that would take a bit of practice to hit every time, without conscious effort. If the spot is missed it either does one or the other or one is quick and the other very slow.

It is easy to see how, if the saleman says it won't work and the operator is unfaamiliar with the unit - where the demo would not be successful.

No offense Cinder, but go try a Kubota, most others, or even an older Deere to see what "true Blending" is like, there is a huge difference.

Ultimately, if you are happy with it, cool, that's all that matters.

(The Deere commercial equipment also offers true blending)

I have a 3320 cab, also one of the first off the production line, and mine won't blend. At least true blending. Tried the different valve positons on the side of the stick with no avail. My dealer and other hyd. people told me I need the power beyond to be able to and showed me pictures of how one works. Finally after deere came out with one for the cab model I got it and installed. I guess you could call it a power beyond, but as I looked at the piping it's just a splice in the line with a choice of return lines. The drawings I saw also included valve modification or replacement to be able to get true blending. Running a hyd. motor while lifting the 3-point is impossible at the same time. Maybe they put a different valve on some of them. Wish I could find out the fix and I'd get it.

2005 3320 and 4-way valve works perfectly.

'07 3520 with fast and smooth blending.

Sounds like something is wrong and a configuration issue is what it seems like. My 3520 doe both and it is not slow as I have inadertently dumped some material by fooling around while lifting it. The loader worked the same on both my former 4310 and the current 3520.

Yep, no problem with it on my unit, except that I stumbled into a simultaneous raise and dump when i turned to look at something that flew by the cab and startled me LOL! Definitely felt pretty silly.

I did contact my local dealers. They told me about the 3way L lever by the loader joystick. I used both the 3000 and 4000 series loaders, and switched the loader switch to both 2 and 3 notches and the loaders still would not "blend". It is like the joystick only has 4 positions...Again--12,3,6,9/

I have used kubotas for 2000+ hrs, bobcats alot, and jd's bigger machines...310,410 extend-a-hoes. All these machines,,,even the Homeowner subcompact kubotas the loaders will blend easily and will true speed.

WHY WON"T THE JD CUTS DO THIS??????

Someone said the power beyond option will fix this..Does it? I thought this only gave me options like a hoe or log splitter on the rear.

Can some jd TECH help? I want to buy this machine but want to be happy with the loader operations. Nothing is more frustrating than spending 30000+dollars and I cant lower and curl the bucket at the same time. THe jd 110 tlb will blend. Why can't js take the loader valve from the 110 and put it on the 3720????

Nuru, Jason Mac, others.........If in fact your machines truelly blend, why do all of these models at 3 different dealers not ?:

My '06 3320 with 300CX blends, but it takes a little practice and works best when the revs are high.

As before mine blends - but I also have PB. Works much better above 2,000 RPM. How it compares to Kubota, I have no idea.

'08 3520 Cab and mine Blends with no issues.. My BIL who is a Cat Mechanic by trade was very impressed with the hydraulics on my machine...
Seriously speaking, I had driven a 3320 PowerReverser when I was shopping, and I dunno if it was a machine issue or me, but there was a BIG difference in hydraulic function...the 3520 eHydro Open was a tiny bit better but it still wasn't as nice as the 3520 Cab I tested (and eventually bought) when I asked about it he said the Cabbed models came with a better Valve & Joystick..All I can say is the blending on my machine is smooth as silk.

Ditto. My 3320 valve likes one operation at a time only, unlike my previous 2 Kubotas. But my tractor is just a toy, so it's no biggy. If I had to do any real work with the loader I would have given more priority to this issue before purchase.

Love my 3320 though.

I have spent the last 2 weeks going to three js dealers. I have worked at least 20 3000 and 4000 series cut loaders at these dealers lots. NONE will blend like I am accustomed to. I showed the sales guys this to no avail. I even started a used kubota on one's lot and showed the dealer the difference. He was amazed!

I am very dissappointed that J D can't build a solid fully functional loader for these cut tractors. Customer support was a joke! After being transferred 10 times, and being put on hold for 2+hours, I was told that "thats the way it is".

I am still very confused by the fact that several posters have said their cuts will blend. Others said their's won't. Am I just expecting too much???
I am willing to even pay extra for a different loader valve,or joystick.

What modifications will make this tractor blend????Come on you hydraulic guys, Help me out.

I want to buy green, but don't want to be mad every time I work the loader and it only performs one function at a time or does "blend " but at a snail's pace.

Curious, when the stick is pulled towards you into curl mode and held there, is it even physically possible to move it towards up or down mode ? (regardless if it was running or not.)

 

[Nuru]

I was on my 3520 today and removing the loader I got blending movements, going up and down, the bucket was dumping and curling without any issue. All I had to do is start the main direction and the vary off the direction just a little and the other movement starts and was easily controllable.

But doesn't it slow to a crawl at that point?

Nope, it actually goes so fast that a few times i did not catch and dumped the stuff i was haulin out before I wanted to and so I ended up with more time on the tractor to get it back in. This happens with the rpms no higher than 2000 rpms, and it is not slow at all, smooth but it is not like you are waiting more than a few seconds for that bucket to tip one way or the other all the way to the stops.

"I am still very confused by the fact that several posters have said their cuts will blend. Others said their's won't. Am I just expecting too much???"

PBT Sisson - I too am confused by this, I have finally concluded that many simply don't have experience with "true blending". (At least as far as the open station tractors, the cab units do have a different valve, and may actually blend, haven't tried one.)

I have tracked this issue since I purchased my 3320 in early 2005, and have yet to see an open station 3X20 trator do "true Blending". As I have said repeatedly, I am a big fan of these tractors, but they certainly have this issue.

This has become a very "tired" discussion over the past few years, please don't respond that your tractor does "true blending" if you don't have at least several hundred hours on machines that do to compare to.

My current 2007 3720 open station will not blend, it slows.

The 2008 I tested at the dealer was a 3520 cab. It blended like the large tractors we own at full speed. This had the deluxe cab and rear scv's, electronic diverter, and I believe power beyond.

My cab 3720 will be here in 2 weeks, I will let you know if it blends. I only have one rear scv added on the deluxe cab.

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.

Looking back, weren't most of the no votes were OS tractors, some slow vote Cab tractors and some fast vote Cab Tractors, but i cannot imagine that there would be a feature difference like that with the same loader and different mounts?

also according to the 2006 Deere literature on the 300 Series Loaders (see attachment) do allow simultaneous Loader boom/bucket operation.
