Yes I see what you mean - solid jackstand under the yoke would probably allow chisel to be hammered in and get it to loosen up.
I will check that out tomorrow.

I think a new input shaft would cost around $1000+ so heating or smacking it otherwise should be avoided.

Update:

The driveshaft yoke was rusted solid onto hydro input shaft, but it did slide out pretty easy after soaking it with ATF & acetone mix for few days, as suggested earlier in post #15 by 5030

The chisels helped to get the penetrating fluid in the right place for sure, but they need to be removed before trying to slide out the yoke - otherwise they will make the yoke to bind on!

So, how's the project coming?

The JD430 is now tentatively back together, but I plan on revisiting the front axle and mower PTO setup bearings after having done little more test driving etc.

The tractor came with 50" mower deck and I purchased a used 60" JD400 deck and am in process of fitting it to JD430 which seems like a not bad fit, but required some fiddling with the front draft arms and pivot shaft.

The deck fits and the draft arms are now good fit:

I am little disappointed that it looks like JD430 mid-mount mower depends on the mower deck gauge wheels for cutting height adjustment, unlike the old JD300, which has easily adjustable mechanical setting on how low the hydraulic deck lift will drop!

IE.
The JD300 middle mount deck does not need to ride on the gauge wheels, which is great when mowing uneven areas like a sparsely forested areas & yard etc. etc.
Relying on the gauge wheels for cutting height adjustment gives more even cut on nice lawns no doubt, but lot more wear on those little wheels - oh well...

Update & correction to above post.


JD 430 does have a mechanical mowing depth adjustment, unlike suggested in the above post!

The mowing depth (the deck low setting) is controlled with the rock shaft adjustment and it works great:

We did a little bit of test mowing yesterday now that the grass is finally starting to grow again.
Our grass has been mostly brown & dormant since late June, which is pretty well normal here every summer.

Update:

After putting the engine to work for awhile I began to notice little uneven idle, unlike earlier so decided to do engine compression test which gave excellent on-speck results - no big surprise with only about 780 hours on the meter.

Next test was a quick fuel injector spray pattern, which turned out to be pretty poor on two out of three!
Took them to a local Diesel shop for rebuild.

Apparently the spare part nozzle body and nozzle valve on these have been updated so hopefully these will last little longer.

Due to (prematurely) worn fuel injectors I also decided to change the original single Stanadyne 10 micron fuel filter to a setup with a 50 micron primary filter, followed by 2 micron secondary filter.

Runs smooth now (that is smooth for a tractor engine).

My advice: get rid of it. A fanboi will pay a ridiculous price.

I have one of these things. I got it for nearly nothing. I think I overpaid. I can't even recall how many times I've been unable to use it because it broke down.

The hydraulic cylinders are proprietary, and they can't be rebuilt. John Deere welded them shut at both ends solely to give a big middle finger to customers. They are way more expensive than comparable generic cylinders, which makes no sense, because they are simpler due to John Deere cheaping out by welding them.

The muffler costs $450, and it weighs a ton. Mine fell off. When I found out what it cost, I replaced it with a stainless exhaust tip and a motorcycle baffle. I think I spent $18. You can get a car muffler for $75. It's not like there is any reason for John Deere to charge so much, other than greed.

The grille is no longer made, and it falls off easily. You can't see it fall off, so you find out it fell when you run over it. John Deere does not sell new grilles. A good used one costs $900. That's because so many have fallen off. Last time I checked the price of a grille for my Kubota (bigger, nicer part) it was $75.

The deck and mulch kit weigh around 340 pounds. To remove the blades for sharpening, you have to pull the deck out from under the tractor sideways. John Deere made it so it won't slide out unless you jack the mower up or partially disassemble the deck.

Taking the deck off is a miserable experience. Depending on how badly your parts fit, it can take an hour for one person. The parts freeze up and don't want to come apart.

The alternator belt is behind the engine, and you have to separate the engine and driveshaft to put a new one one. Lots of fun for people who like lying on their backs under dirty tractors, turning wrenches 5 degrees at a time. Expect the

Some people talk about the 430 like God himself designed it. They get really angry when you criticize it. Those are people who love collecting and repairing tractors. They actually prefer machines that need a lot of difficult repairs. Don't listen to them. A tractor should be made for people who use tractors.

It really bugs me to see people talk this tractor up to others who are thinking of buying them. They are leading them into misery.

John Deere keeps discontinuing essential parts. Pretty soon, these things will be impossible to repair without custom fabrication and machining.

It's going to get worse.

The tractor is a horror to repair even when you can get parts. I guess you know that now. Have you removed the sheet metal to get at the parts beneath yet? There is really no way to get a wrench on the hex on the lever on the right footrest. You have be creative.

On top of all this, the 3-point hitch and loader are Barbie tools. Really small. The loader is rated for 500 pounds. Try clearing hurricane debris with that.

I keep looking for a good used Kubota diesel zero-turn. They come with jacks built into the decks. If you need to sharpen the blades, you turn a little handle with one hand, and up the deck goes.

I know a zero-turn isn't a tractor, but there has to be a better tractor out there.

Great news: John Deere discontinued the rockshaft cylinder (rear hydraulic cylinder). Before they did that, they jacked the price up to about $450. A reasonable price would be more like $100.

No rockshaft cylinder, no tractor.
