Hey yall,

I'm new on here and I'm still feeling my way around the site so if this is in the wrong place then please move or do whatever you need to do... Tonight I am on my way to pick up a JD 400 for $700 that runs and drives and is in pretty good overall condition. From what I've seen this tractor was the top dog in its day and a bunch of new attachments were made for it, but I don't know where to look for them. Craigslist? I really only want a integral hitch (sleeve hitch) for it, but I'm not sure which one would fit a 400. Same as 300 series? Where could I find one? I'm used to 140's, 110's and 112's so I might be going a little big here..... Any info or comments would be great. Ill post pictures if I get around to it. Thanks in advance!

Welcome.

400 attachments are not plentiful. Search anywhere and everywhere.

For a sleeve hitch you will need a 3 point hitch and a sleeve adapter. Reugg is my choice for 3 point hitches.

Welcome to WFM! And happy new project!

The attachments for the front and the mower deck are the ones that are pretty specific to the 400. I didn't get very concerned about "bolt on ready" front implements. Once you're set up with the Cat 0 3 point hitch, that opens that whole world up. The 400 is a substantial GT and worthy of some effort.

Top of your project list should be putting on an oil pressure gauge. Then fill in the gap around the oil filter. Those will go a long ways to prolong the engine life. Lots of great help around WFM. Good luck! Jay

Welcome to forum, there are few of 400 "black sheep"guys around. The implements will be challenging to find, but they are out there. I can tell you some of us 400 guys know where some are or have a couple extra of our own.:yahoo:

Here is the tractor I picked up for $700. Runs great. I tightened the bolt on the hydro lever because that was loose, other than that everything is awesome. Land vehicle Vehicle Tractor Agricultural machinery Riding mower

Don't they have laws against stealing where you live!?

Great pick up!

Guy bought it from a fellow John Deere worker but was only interested in the snowblower that came with it so he sold it at a good price because his wife wanted garage space :yahoo:

Good deal. It takes a good man to keep tractors in the garage over the wife's car. A true Ninja would have added an outbuilding to keep the peace.

Okay guys I ran in to my first issue. Idk how I didn't notice it but the rear right axle housing has a broken ear and I was wondering how hard they are to swap out. There are plenty of replacements on eBay but I'm just wondering how tough they are to change. Any seals involved?

thanks!

I haven't had mine apart, yet. But I do have a little weeping when it sits for a long time. It looks pretty easy and there will be seals involved but not a bad idea to change them, anyway.

Sign up for free at jdparts.com and you'll see parts diagrams, part numbers, and specifications. I use it all the time to give me assembly clues. Here is the axle assembly diagram:

Pulling the brake drum hub can be the toughest part of the swap. Some are a real bear and require a good hub puller. Others are easy, especially if the the outer axle seal is leaking fluid into the hub-axle connection (hope this is the case for yours Jay). Check the outer bearing in the axle tube you buy, as sometimes the bearing begins to spin in the tube or on the axle and cut a groove. Be sure to put thread sealer on the bolts (#5) holding the axle tube to the transaxle case, as the threaded hole goes through the case and will leak otherwise.
