Drop the front drive shaft cover. There should be a rubber coupler and some hose clamps holding the two halves. Use a big screw driver or pry bar and push each ends in to the center via the welded on tabs. This will expose a stub on each end much like a pto stub. There should be 6 ball bearings in there I think and a clip holding them in place. Its been known to have the clip fail and the balls drop out. They should be in the shaft cover so be careful when dropping it to not lose them.
There is some good write ups on the fix via this site. You can use the search to find what you need.

I have seen several posts where it was suggested that you try forward/reverse movement then engage. Even to the point of a very/very slow movement when moving to engage. Lots of things to line up it seems.

Are you sure it is engaging? You need to be rolling when you engage 4wheel drive on these tractors. Just hold gentle pressure up on the lever while driving/rolling and eventually the 3 toothed pawls will line up and engage. The pawls look like a pie cut 6 ways with every other piece removed The 3 trianglar teeth are flat faced and must be aligned to engage. One is connected/driven by the gearbox, and the other is driven by the front end, and when rolling they turn the same way, but at a slightly different speed so you must be moving for them to come into alignment. The lever will move a little bit to take up the slack and bring the teeth faces together, but when the teeth align, it will pull the rest of the way into 4X4 position. IF it does this, and you are not getting pull from the front wheels, then Chris's suggestion would be my next stop. As suggested, do this over a tarp or on a clean garage floor, as sometimes the ballbearings try to run away when the tube is removed/lowered...
