I still say check that flywheel, just starting makes me think that flywheel is starting to move out on the crank and when that happens it gives too much play in clutch disks and with too much play they will rattle. I forget the model of your tractor but if it has a closed flywheel then there is a nut on the end of the crank to use to tighten up that end play, now an open flywheel tractor does not have that nut and is harder to get flywheel tight. You need to find a way to put pressure on clutch end of crank to hold it tightly to the left while you drive in the flywheel, with out holding the right end of crank then the crank moves to right as you try to push flywheel in and you think you are getting it moved but you actually are not. It may be only like .005 clearance and do that, doesent have to be enough you can see movement in crank. We had that same thing on a couple of them. One was the 49B, other the 38A. The closed flywheel it is easy to get to the flywheel bolts to tighten but on the open flywheel the bolts are on the back side where there is not enough room to get a wrench in and Deere made special wrenches for that, A &G you could do with normal wrench but not the B and that was one special twisted in many ways to get in there wrench. That end play is first thing to be checking and only then but you need the clutch apart when checking that end play do you start to put the clutch back together and while you are doing that you can tell if there is any ware on anything in there. The bolts that the adjustment are done with are very prone to wear and when they do they get a notch that catches the clutch operating parts in and you cannot get the clutch dissenguaged and you better hope you have the opertunity to kill the engine as that is the only way you will stop the tractor when that happens. Luckily hours was battery ignation with a switch to stop the engine. Those flywheels have been known to slide completely off the end of the crank while engine was running. and they will travel hundreds of feet before they will stop and there had better be nothing in their way or it is destroied. Heard of one flywheel that went in a swamp never to be able to be recovered.

In the exhaust you can hear an occasion 'poofing' sound like somethings not firing on all cylinders.
