Small Engines (Lawn Mowers, etc.): Ford 100 rear end, mechanic work, old ford

Question
I have got an old Ford 100 tractor that I just got running a few weeks ago.  It was sitting in a barn for a very long time.  The only problem is that it does not move.  Something in the rear end seems to be keeping it from rolling.  Is there anywhere online that I can get a diagram for the rear end or can you help me out in any way? Any help is appreciated.  Thanks.

 Hello Brandon:

 Go to this Addy http://www.ssbtractor.com/tractor_manuals.html They Dont Offer Online Manuals to Read. They have them for Sale. The Cost for the Manual on the Transaxle is $28.95. I would Suggest you Purchase this Manual and All the Others Over Time. You will Need Them. I Find Tractors are Big Mowers in a Way. The are of a Simple Design and Just About Anyone with a Manual can Do the Repairs. The Problem is Most Likely Going to Be the Bearings. I have Found PB Penitrating Catalyst to be the Bust to Use When Trying to Free the Bearings. Depending on How Bad they Are I Suggest you Replace All the Bearings that have Signs of Rust On the Ball or Pin Bearings. Enjoy Your Project. If you Love Mechanic Work this will Be A Joy. Im Here if you Need me. Let me know what Happens, Please. I enjoy knowing the Outcome. Thanks.

 Good Luck

 Respectfully
