clueless,
Under the seat, there is a small plunger on the left side that you must pull up in order for the tractor to free-wheel. You have to hold it up while you're moving it.
Here's a pic of the front deck assembly...

There are some cotter pins that hold the assembly onto the front of the deck (10,11)
and the other end has a couple bolts that go on the threads.
