How do you know the battery is good?
Did you also try to jump start it?
Check all connections on battery and solenoid and starter.
I had one that turned out to be the starter...even though I thought it was good.
 
Engine is hard to turn with a breaker bar ??????? Hmmmm seems like a hydro lock or a semi froze engine.....

Pull the plugs and then try to turn it over........ If not then try the bar again.... If still hard you got a froze engine on your hands.... Mon Ami ..

Let us know something ~!~!
 
Have you tried rotating it with the plugs out ..?? Is it any easier that way ..?? If so.. may need valves adjusted.......or maybe a broken key-way........
 
Had a similar problem with the dixon a week ago...battery just clicked..
engine was froze for some reason. This has happened before and it
seemed a simple matter to just work on the rotating screen..get it
to turn and it eventually would free up and start ok..run ok. This last
time I got it free but it was hard to start. It backfired once and oil
started running out of the vent tube. So I tore it down to where I
could pull the tube out..cleaned it all up put it back together...AND, checked
the oil..Was on inch over the full mark! wtf! Drained out to the half full
mark and she started up first crank..blew out smoke for awhile and then
started running clean...still does.

This is what happens when the float valv in the carb fails to shut off the fuel supply.
Fuel leaks out of the carb vent which by law now days has to be inside the carb so it overflows into the carb throat, down the inlet valve into the cylinder past the rings and into the sump.
Very important that you check it again before you start the mower.
If the oil is high again then remove the spark plug & rotate the engine as quick as you can by hand to remove the fuel in the cylinder, then change the oil twice and the filter on the second change.
Remove the carb and clean the inlet needle & seat.
Check that the needle is stopping the fuel supply by having some one crank the engine while you hold the float bowl up with your finger.
If the fuel does not shut off before the float touches the carb then it is time to replace the needle & seat.
