JDcrawlers Messageboard

Ok, that makes sense to me. So I don't need to worry about that now. All I have to do is find a double hydraulic setup and the levers. Any ideas on where to find them and a new set of fenders???

So, looking at all the pictures that I can find with crawlers with 3pt hitches on them, I am guessing that they do not have a blade on them. They are equiped with a double hydraulic system and show the hydraulic cylinder that operates the 3pt hitch and also show a breakaway coupling system on the ba...

I'm not sure how they were able to operate both sets of valves from the picture. I wonder if the second set was an emergency backup incase the one set quit working??? Looking at some other picture of crawlers with 3pt. setups on them I was wondering how you operate the hydraulic cylinder for the 3pt...

Here are the pictures of the hydraulic valves from chickenman.

https://jdparts.deere.com/servlet/com.deere.u90.jdparts.view.publicservlets.HomeUnsigned On the left side of the page click on "JD PARTS CATALOG" just under "Start Searching Here" It will take you to a different page. You will now see the parts catalog page. Type in 420 in the model search box then ...

You can send the pictures to me at my e-mail address and I will post them. It sounds like you do have to double setup. The dozer blade was controlled only by one valve while the rear hydraulic cylinder was controlled by the other. From the sounds of it your other set of spools are plugged since they...

By the way here is the seat frame that is currently on the 420. Is it the correct frame??

Jim, thanks for the information. I do not think that the seat that is on my 420 is the correct one. It looks like the seat for a special/utility 420 as shown on pg. 90-6 in the parts catalog PC0505. I also agree with you about the linkage issue. I guess we will just have to wait and see. Any idea wh...

Is there any way that I could get a picture of your 4 spool setup that is mounted above the hydraulic tank? I have never seen one mounted like that.

Also, does anyone know if a delux seat will work with the 420 with a 3 pt hitch??

Thank you for the information Jim. I had a feeling that I was going to have to be patient. I guess before I find the 4 spool setup that mounts on the fenders I will need to find a set of fenders to mount it on...lol Thank you again for the input.

Well, here is a picture of the 420C that I was finaly able to pick up.

what are your plans for the street pads??

Looking at the parts manuals for the 440 and 420 the sprokets will interchange (T16261T or T16259T) and the pads from looking at them are also 2 bolt and will interchange.

I just picked up my first crawler, a 420. The person who sold it to me saved a 3pt set off of a 440c and later purchased a 62 blade for the crawler but never installed either of them. When I took a look at the hydraulic system on the 420 I noticed that it is only a single system. I believe that in o...

Well, I know that I don't have to try to take it apart but it is going to be fun to try and figure out if it is all there when we do go pick it up. I'm trying to figure out the best way to check it off as it gets loaded. Also, what the best way is to carry it all home on the trailer...
