I would suggest to take a look at the air filters, even run the engine for a couple of minutes with no air filters in it just for a trial.
Is it consuming engine oil.?

Not being familiar with a 953, a serial number would be helpful! Does it have some kind of pre-cleaner before the actual air filter? I have seen where they get over looked and get so plugged that even with new filters in the housing the restriction can be enough to trip the restriction gauge.
Now that I mentioned that restriction gauge does your machine have one? They are often mounted in the piping between the filter housing and the turbocharger.

What I was asking is do you have to top up the engine oil on a regular basis.?
Did this problem start suddenly or has the smoking symptom been slowly getting worse over an extended period of time.?
Have you pulled the dipstick to check if the engine oil level is not excessively high.? That could indicate an internal fuel leak.
Last question, for now at least. Do you have an Operation & Maintenance Manual for it.?

And if you wonder why we ask for the S/N just take a look below at the list below. Note that those are only the prefixes (first three letters or numbers of a S/N). Each one of those could have several breaks in the number range that will in many case indicate major changes to some parts of a machine.
Not trying to be a jerk, can do that without trying most days, but trying to be sure you are getting the best answer possible.

So the smoking was not an issue before it was parked 4 weeks ago.?
Try removing both inner & outer air filter elements and start it up. See if the smoke levels change.

No it never smoked like this before it shut off, After I got it started it started smoking. So to answer you're question It did not smoke before it shut off on me

Right. Pull both air cleaner elements and start it up without them, just for a couple of minutes. Report back what happens.

Alright ill record a video

You don't necessarily have to record a video. Just see if the smoke level reduces or even disappears completely.
When you pull the air cleaner elements out, take a good look at them and "weigh" them in your hand. Air cleaner elements are not very heavy, but if yours have absorbed significant quantities of water somehow they will feel like lifting a brick. The larger one should only weigh 6 pounds, the smaller one 3 pounds.
While you are testing it would be worth opening up the precleaner assembly (circled) and give the bowl a good clean out.

If you do remove it wipe the filter housing with a wet rag to get rid of any residual dust before starting.
