1650 good or bad
 

Am I supposed to be able to push my 1650 hydrostat around while the engine is not running it's like its a gear drive in neutral I was just curious everything looks fine and the hydro isn't acting wierd

Sounds like you've got the automatic release valves.

While sitting on the tractor, if the valves were manual, there would be a lever on the right side of the tunnel cover. You would lift this lever to release the valves so you could push it around. If there isn't a lever, and she pushes easy, it would have the auto release valves as Duke mentioned. Some of the manual valved tractors may have been switched to auto release valves by a PO, so it may still have a lever with auto valves. You could always pull off the tunnel cover and see what ya have. Nice 1650 BTW!

I have a 1650 with no release valve and it rolls fine in neutral.
