Hydrostatic Drive Problems??

I got this tractor as part of the deal when I purchased a small acreage. My guess it is about 5 or more years old. It has worked flawlessly for a couple of years now (except for a battery) and I maintain it carefully as I do with all my 'tools'. I have no documentation on this product and I usually rely on the internet for any information I don't have regarding maintenace for all of my toys and tools. This tractor just doesn't exist according to Sears. When I visit their parts site they have no information on this model.
My problem is that while I was mowing on level ground, the tractor simply slowed to a stop. No pops, pings or bangs. The engine starts & runs good as do all the attachments but the tractor just won't move. It does make a light 'whine' when the control lever is pushed ahead or back as it always has but other than that nothing happens. I have removed the fenders, tank etc. and have lifted the rear wheels off the ground. It sounds like the pump is working but something is just not engaging. Any suggestions where to start?
