I'll second Jack's comments.
Been there, done that, regretted it...

Mine is a 70" prop.

   I have a 72.5 inch propeller and twice two different occasions I have
made ground contact with the prop.  I have a 6" nominal ground clearance but
the nose wheel is so far behind the prop that a little dip in the ground can
put the prop into the ground.  The second time I bent the tips a little and
to be safe, we took the engine apart and reoverhauled it. It is disgusting
to overhaul an engine with 300 hours on it.  The good part is with 300 hours
engines don't have much wear. Everything was like new inside, but it made me
feel better to have looked at it.
    Now I don't get off the pavement. If anyone directs you into the grass
stop and shut down. There has been no problem on pavement. Pulling is much
more prop safe on grass.
