Trans leak at seal
 

Another from the, I'm Not A Mechanic And Should NOT Play One In The Driveway:

Tranny leak at the axle seal - left side!

Is this a BIG job? Or is the seal replaced much like an engine seal?

And another thing - I've never been able to move (push) this tractor when it was not running.
Now, for some reason, its relatively easy to move around. Entirely baffled by this.

To change the Axle Seal.....
(A) Drain the Rear End
(B) Pull the Rear End Cover off
(C) Locate the effect axle on the differential
(D) There is a "C" clip at the end of the axle
(E) Remove "C" clip
(F) Pull axle out of axle tube
(G) Remove bad seal
(H) Install new seal
Reverse your steps to restore your rear end.

New Parts:
(a) Rear Cover Gasket
(b) Hydro Filter
(c) Axle Seal
(d) New Hydro fluid - ie: HyTran

Rear end should be be cleaned out and up before reassembly.

What model tractor are you working on?

Edit: I see from your other post that you are playing with an 1882. Pretty much what Roland said but you also need to remove the brakes to pull the axle. This is one I did a few years ago.

Thanks for the info guys.
Do you have any insight into the moving and not moving of the tractor mentioned earlier? The why's, what's, and how's of the fact I couldn't, but now can, move it.

That issue would revolve around the Sundstrand Hydro Relief Valves. Pull the relief valves out, and soak them in a cleaning solvent. Once cleaned, blow them out real good. then reinstall.

Report back and advise.

Once this procedure is completed......the tractor "should" or "should not" free roll??

Normally, once the engine is off, and the pump pressure is down (a few seconds), it should be free to roll.

These are the "SU" prefix numbers under the hydrostatic trans section of parts breakdown??

Part numbers with the SU prefix indicates the vendor is Sundstrand.

How is the C clip removed? I can't see the holes on the clip to where snap ring pliers would help. Is it a matter of positioning the axle so the holes are available?
