Hi, I am a new user and have learned alot from searching this forum. Thanks for all of your help, your postings have really helped me. In a small way I wanted to return the favor so I am posting the following info that I have gathered about adding a 40 loader to a 425.

The part number for the transaxle pressure relief valve is AM121248
The Control lever part number is M121509

Hooking up the hydraulic lines:
upper left=yellow
upper right=silver
lower left=black
lower right=green

The lockout valve I found on Ebay from thegreendealer. Sorry, don't have that part number. I have purchased a couple of items from them and have been very happy with their service and pricing. (local dealer wanted $269 for the relief valve, I bought it for $200 from thegreendealer)

There are shims available for increasing the implement PSI. CHDinCT is sending me some of those, I don't know the specifics of them yet, hopefully he, or someone else with that knowledge, will add that to this thread.

Please add anything you feel would help a newbie like me!

Hi, Thanks for the welcome. I also am running 8 suitcase weights in a bucket on the rear of my 425. Any ideas as to what air pressure I should be running in my tires?...I already have them half full of antifreeze.

I don't remember what the suggested pressure was in my 425, but I'm thinking with all that weight, that you should run it close to the max. :)

Welcome to the forum. I'm relatively new myself.

Have a few questions...

What do these do? and why are they required?

"The part number for the transaxle pressure relief valve is AM121248
The Control lever part number is M121509"

I've got a 425 that I fitted a Danco loader to. Have a thread in the maind accessories seciton here: http://www.mytractorforum.com/showthread.php?t=80838

have any pics?? Do you have a 3 pt hitch?

Hi bvp2000 , :Welcome1:

IMO , run them at the pressure that's stated on the sidewall ...

Hi, Thanks for the tire recomendations!
I am awaiting my parts for the transaxle, I will take a few pics and post them as the job proceeds. No, I do not have a 3 pt. hitch....I have a weight bucket there. As far as the need for the parts...I will leave that answer to the more experienced members....

A little history of my 425 and 40:

I actually was looking on craigslist and it was listed as a mower...not a 425. I called the guy (4hours away) and he had no idea if it had hydraulics, PTO or any capabilities other than cutting grass. It had 412 hours on it. He didn't know how to upload any pic, but said he wanted $2500 for the mower. I got my trailer and went down to look it over...it was in pretty good shape, except a chip out of the hood and one of the deck wheels and frame were bent at about a 45 degree angle! Well, upshot of it was I paid him $2200, came home, took the deck off, heated the deck frame and bent it back in place. Also had to braise a small spot or two. Put it back together and cut my lawn, 1 1/3 acre, and was very pleased with the 425. (Even more pleased that the deck still cut level!!)

Then I started looking a 3 pt hitch and box blade, while searching for those items I came across a 425 with 40 FEL with 110 hours on it for 6K. I called and asked if they would consider separating the loader from the 425 and to my surprise he said that he had a buyer who wanted just the 425 and was willing to sell me the loader, with weight bucket and weights for 1K. That night I headed out (5 hour trip one way) and was at his location at 8am....I didn't want him to have a chance to sell it before I got there! The loader was in showroom condition...turns out it had been in storage for years....checked the hydraulics and everything worked perfectly. Having talked with a few friends that have bigger FELs they all agreed that I would get more use from the FEL than a box blade. Can't wait for my parts to come in so I can give this rig a workout!!

BTW Installing the framework for the 40 loader on the 425 is a breeze....just take your time and anyone can do it.....although I was lucky enough to have watched it being taken off of the other 425...that was a big help as well.
Well, that's my story....more than many will want to know....lol

OK...Here are a few pics....It is pretty dirty, I just came out of the woods in the background and it is pretty dusty here. I have installed the pressure relief valve....still waiting on a gauge and shims before I try to increase the load capability a little. Gonna try to bump it up to about 1250 psi.

Also...here is a link to a little video about a dual hitch for lawn and garden tractors. Most ppl here already have higher end hitches...but this was something I needed and so I made it. It is fairly cheap to make and is good for alot of general use. I sell them on ebay for 12 bucks each for the plate only....unfortunately some others have started making and selling something similiar, guess they thought it was a decent idea...lol

That is a very nice looking tractor. What's the current lift capacity?

Hi

I would think twice about raising the pressure for the loader. The system is pressure limited to keep the lifting capacity down to a safe level for the tractors weight, tire size, wheelbase etc. If you increase it by 25% (stock is 1000psi I think) you will be creating a situation where you could overload the axles, tires etc and be more likely to have a rollover. Since you don't have a ROPS this could be fatal.
Ask anyone who owns a loader on a 2305 which is similiar in size to a 425 but about 6oo lbs heavier. They have often had close calls with the loader.
Just be very careful if you do this. I would stick with stock limits myself.

I am also new to all of this but to me, that seems like a great machine for $3300. Congratulations and thanks for the photos.

bvp2000,

Just saw this thread. The shims for the JD 400 and X series are 10mm outside diameter by 5mm inside diameter. You can buy them in various thicknesses but the ones I got are .3mm thick. I believe I added 3 shims to boost pressure to 1,250 at WOT. I've read where some owners boosted the PSI to 1,700 or 1,800 with no issues so I felt comfortable with 1,250. Plus, you can get the spec PSI of 1,000 at lower RPM.

Well, I got all my parts in and have installed new quick connect couplers, four .3mm shims, (which brought my PSI to 1260 at WOT) pressure relief valve, lockout valve and new control lever. I also have changed the oil, hydraulic fluid, filters, plugs and air filter. I greased every fitting I could find...and someone on another post mentioned the grease fitting on the rear of the u-joint....THANKS...I would not have found it if I hadn't seen that post!

I have been using it today and am very pleased with how it is working..Only thing left is to get is a roll bar...just in case!

Thanks for all the help I have recieved on this forum and through emails...you guys have been great, hope I am able to help someone as you all have helped me.

im new to the forum here but I just got a 40 loader for my 455 and was wondering if anyone knows exactly what you need and the part numbers I have bounce all over this place and a lot of answers are still loose..

and does anybody have a link for the pressure gauge I don't know what kind to get or what fittings are needed because I will shim the valve as well

Pick up a 1/4" npt 2000psi gauge from McMaster along with 10x5mm shims I went with .3mm thick then you need to get the male quick connect fitting for the gauge from McMaster as well. You will also need the transaxle hydrostatic relief valve get the one for a x475 or 2wd x700 series they are the same valve and much cheaper.
