Just went out to play. MY tractor and I are taking alittle trip next weekend so I loaded it on the trailer today to check some things. Trailer is a standard gooseneck with bed over the wheels. I noticed when unloading the tractor (3520 w/ e-hydro) it will ease off the trailer very slowly without pressing the pedals; almosts unloads itself. Will this hurt the transmission? Should I apply alittle pressure to the reverse pedal? This is my first non-clutch transmission and I do not want to tear it up.

From what I understand you to say, you can't tear it up doing this. Is it coasting in reverse, and not holding it from rolling back? Getting on the reverse pedal would just speed it up and go faster. If the coasting is the speed you want, enjoy it.
I would read the book about 'coasting' and see if there either is an adjustment needed or if there is a setting of the ehydro that needs to be changed (i.e. make the reverse pedal more effective).

Maybe the original poster is wondering about damanging the hydro? I've heard never to push or tow a hydro.. friend of mine blew out a seal.
So wouldn't letting it roll be the same as push/towing?

The operator's manual on my DX33 states you can tow up to 12 mph in neutral.
HST tractors will normally creep at a slow speed when on hills. This is because an HST is a fluid drive and inherently there is some internal leakage that allows the HST motor to turn when back-driven by the wheels. With the engine running, which allows the leaked oil to be replenished, you can creep down hill all day without harming the tractor.
Now if the tractor isn't running, the internal leakage is not being replenished, and after a short while (many seconds to a few minutes) of slow creeping there will no longer be any oil to resist the HST motor and the tractor will take off down hill at a higher rate of speed. This can damage the HST after a long downhill run. If you want to try it on a short hill for your education, a few feet travel isn't going to hurt it. Just be prepared to use the brakes to stop.
Towing an HST tractor with the gear selector NOT in neutral also will cause the oil the oil to leak out internally eventually resulting in HST damage. Putting the gear in neutral disconnects the HST from the axles and allows you to tow to whatever speed and distance is recommended in the operator's manual.
