Not to be too redundant here but since I used everyone's advice when greasing this fitting I figured I would post my experience. I only loosened the top and lower dashboard by removing the estimated 9 bolts to gain access to the hidden panel. I tried using the workforce 6 inch push on coupler - quick connect to grease the fitting but found that the 3 inch straight needlepoint coupler - quick connect worked easier for me. The whole ordeal to grease just this one fitting took about 20 minutes. I will say that I had my father helping. The picture, if attached, is of the needlepoint coupler that I used. It was purchased at Tractor Supply. Hope this information is useful to someone else. Thanks guys.
I'm not sure what all the fuss is about. I remove my mower deck, slide under the tractor, sometimes several times after moving the tractor back and forth to align the driveshaft just right, then I reach up with a regular old grease gun from tractor supply and give it a few pumps. If you are physically able to crawl under your tractor this shouldn't take more than 2 minutes after the mower deck is removed.
I cut a door in the plastic so I could get to the access plate.
If you do this becareful of the wires on the back of the plastic.
I'll try to attach photo.View attachment 258884
