John Deere 175 Hydro - how to move without starting?

I have an old John Deere 175 Hydro that came with my house. I haven't been able to get it started yet, but plan to work on it over the winter.

My question is - how can I move it without starting it?? The mower is in neutral, but it won't roll. When I jacked it up to test the wheels, they spin in opposite directions when I move them manually.

I have a little lever or pin on the back of my newer John Deere that allows it to freewheel, but this JD 175 doesn't have one (at least not in the same place).

Any ideas?

Thanks!
