Thank You everybody for your input. Sears called this morning at 6:30 and said the tractor would be there in about an hour. At 9:15, the guy showed up. He knew little about the tractor, he had recently moved to Eastern PA from Brooklyn, NY. Thanks to this thread, I was able to quickly remove the deck, I wanted to spray the bottom with MoDeck. (I read that it would help allow the grass to exit more freely). I purchased the product at Tractor Supply, $8.00.I put furniture sliders under the deck, and was able to move it freely from under the tractor on the garage floor. It went back on without a problem.
This is one powerful tractor. Although this is my first rideon mower, I have watched our landscaper race around on his Xmark for $75.00 a week, and this thing seems to do a comparable job. Obviously, it does not back up as rapidly, but it should pay for itself.
As for 'The Transmission Purge'. They left the requirement to accomplish the purge in the Before Start Checklist, but removed the procedure from the manual. I did the one outlined earlier in this thread, it was really simple.
I really had fun mowing the lawn! Thanks, Jim
