OUT WITH THE L4330, IN WITH THE L5030

[Muleskinner]

That's what I thought, but there is no pump there. /forums/images/graemlins/confused.gif

The front of the crankshaft has a splined shaft protruding forward from the drive belt pulley about three inches, but it's not connected to anything.

Could it be there is one pump that somehow splits off the hydraulic flow to loader/hoe and boom swing while the other is simply for power steering? The power steering pump does move 6.2 gpm, a sizeable amount. I have found one thing about Kubotas that seems to always work exceptionally well and that is the power steering.

 

[Muleskinner]

I doubt it. If Kubota says three pumps, I'm sure there are three pumps. Where the third one is mounted is anybody's quess. One of these days I will invest in a Kubota repair manual for it. That should answer my question.

my 48 has a pump under the radiator and I guessed the 39 was the same

 

[Muleskinner]

Okay. I am going to attempt to post a picture of my new L39. I have never been able to post a picture here before, so if it does not work, I will need someone to walk me through the process.

Okay that did not work. I need help. Walk me through the process step by step. My tractor pictures are in the file "My pictures" and are in Jpeg format. Under "Instant markup" I tried clicking on the "Image" button and it asked for a URL. What is that?

To attach a picture you need to click the box below the "Post" window that says "I want to preview my post and/or attach a file ". When you click on "continue" the new page will have a line that says "You may attach a file if you like (no bigger than 100000 bytes please).". Click on the Browse button to the right. Find your picture file on your computer. When you find the file double click on it. This will put the file address in the box next to the "Browse" button. File must be smaller than 100K.
Click on "Post This Message!". In a few second you should see your attachment of the picture at top of your post in the forum.
Using the Image icon will put a image in a post. It must be stored on a server. Not your computer. It is frowned on to post images within a post. It takes much longer for our fellow TBNers that are on dial up to load these pages.

 

[Muleskinner]

My pic says 980 KB. Is that too much to post, as I tried your method and after about five min I get a page that says this page cannot be found??????????

The diff lock is generally used with the hand throttle or at idle in really low gears.

Ag tractors almost always have it on the same side as the throttle pedal so you can feather the clutch.

That is much to big. You need to get the size down both in terms of dpi and the screen pixels. I would suggest about 400X600 and the dpi at no more then 75 dpi. You need a prgram to do this. I use Photoshop Elements but there are plenty of others to help you get the size down.

 

[Muleskinner]

Sounds way too complicated. Looks like I won't be posting any pics. /forums/images/graemlins/frown.gif

Email it to me, I'll downsize it and send it back. I'll PM you my email.

 

[Muleskinner]

My B7800 and the L4330 are on the left side. If I need to lock up the rear end I want to be able to operate the gas pedal while doing so. Idle speed won't get it trying to get out of a situation where I need the pulling traction of both rear tires. Using the hand throttle while operating the back blade or the FEL at the same time doesn't get it for me.

 

[Muleskinner]

Okay. Let's see if I can figure this out.

It did. Hit attachments the pic of my L39 is there. /forums/images/graemlins/grin.gif

 

[Muleskinner]

Here's another one of our toys.

 

[Stef]

Wow, that's a big toy... lucky man /forums/images/graemlins/grin.gif It looks like some people have more playtime than others. /forums/images/graemlins/frown.gif Nice L39 on the other pic.

 

[Muleskinner]

Yes well it's actually my partner's tractor. He bought it last year before we got together. (Business wise that is)

He does the rock work and I do the small stuff. (Small in comparison /forums/images/graemlins/grin.gif) The D6 is a monster. /forums/images/graemlins/shocked.gif It weighs 35,000 pounds. The front blade weighs around 10,000 pounds if my memory serves me right. The cab is air conditioned climate controlled and for the most part air tight. It has an awsum stereo with a CD. /forums/images/graemlins/wink.gif

The tractor stays booked up six months in advance doing house pads and roads in the rocks. I like to run it, but it's hard on my back, even with the air ride seat. /forums/images/graemlins/frown.gif I like running the skip loaders (L39) and the B7800. He's an engineer and has over 5000 hours on track graders and loaders. I'm just the flunky. /forums/images/graemlins/cool.gif

That's me in the picture climbing around on it. It's a real climb to get up on it. As you can see we do a lot of work in the desert sand. Most of it is decomposed granite. Some is real fine like blow sand. That's why I had a power problem with the L4330.

 

[Stef]

Muleskinner, I'd like to know: with a bulldozer like that, how do you level an area? I mean do you have a tiltmeter onboard or a light coming on when the machine is leveled and then you level the rest of the area? Is there tilt cylinders on the front blade?

I know it might sounds like dumb questions, but I really don't know how commercial tractors work.

Not that theres anything wrong with that. /forums/images/graemlins/grin.gif I do like the clarification at any rate.

 

[Muleskinner]

It's hard to explain. I will try. With a dozer it's different than leveling with a skip. Let's say you are leveling a pad on the top of a small hill for example. Once you get your road made to the top of the hill, you start from the top moving back and forth in sort of a semi circle as you take the hill down in elevation.

During this time you are grading "By eye." When you get the pad close to where you want to be you use a lazer level to obtain the finish grade.

The tricky part is climbing the mountain to start. To accomplish this you actually back the tractor up the slope a little at a time then start grading the road downhill. Most folks think you grade going forward, but that's not how you do it.

All pad and road grading jobs are different depending on the terrain and what your customer wants. With a dozer you kind of move back and forth turning around in a semi circle moving dirt. This takes the material down as you go. Clear as mud? /forums/images/graemlins/confused.gif

On a semi flat surface you grade like you would with a skip. The D6 has the lazer level option from Cat. It's trick. The receiver mounts on the center of the blade. The sender is set up on a tripod. Inside of the cab is a computer type screen that shows you your grade mesurements. With a single receiver the blade has an auto mode for raising and lowering the blade elevation automatically. With a double receiver the blade's auto mode controls both blade elevation and tilt. If you are a large contractor Cat even offers a GPS system that can control more than one machine at a time. It's all about how much money you want to spend.

It's hard to explain on paper. You need to watch a dozer grade from start to finish to understand how it works. It's definitly an art. /forums/images/graemlins/grin.gif

Yes Rat. Living as close to Palm Springs as I do I wanted to clarify that. /forums/images/graemlins/grin.gif
