SOURCE: Fuse blows when engage blade

The electro-magnetic coil side of your PTO is shorted out.On the 318 it is very easy to replace,just under front screen.

SOURCE: BLOWING FUSES

Ist of all is 10 amp the proper size?
2nd if you bypass and whatever you are replacing the fuse with, is it warm, or hot to the touch?
If it is you have a direct short in you have a direct short in the electrical system. Check for bare wires,wires touching the motor or chassis that don't have a connector.
Hope this is a FixYa

SOURCE: My riding mower blows fuses once you turn the key.

Sounds like you are on the right path, maybe some wires on the ignition were replaced backward, and you are sending +12v directly to ground? Does it blow right away?

SOURCE: LTX1000 42" 18HP Kohler - Blowing fuse after 2-4 min mowing.

sounds as though you are on the right track
but be sure to check the wiring directly from the electric clutch on the front of the motor back to the switch
a wire could be pinched in the frame and shorting out intermittingly
look around and find those wires and move them around and look for chaffing and tightness
and what you could also do is to unhook the clutch at the connection to it at the front of the motor and engage switch and ride around and see if fuse blows and if not you may have an electric clutch issue

SOURCE: The charging system on the mower will not charge the battery up

The first thing to check on this machine is your voltage regulator try bypassing the voltage regulator to see if the alternator starts charging, it would be better to check your charging system with a voltmeter so that you know what the exact input and output in the electrical system.

John Deere Tractor...If you put a battery with more cranking amps than what's called for will it blow fuses? When we start the mower it continues to blow fuses. This was after the battery change.

NO
a battery with a higher crank specification only means that you can spin the engine for longer before the battery goes flat
blowing fuses is from a dead short in the wiring, battery connect up wrong, problem relays
basically the positive of the battery is through the fuse) connected directly to ground at some point

On my John Deere lx173, when I try to start it, it blows a fuse. All wires look good. What could be wrong?

it could be a bad component in the start up system, like the fuel pump or a fuel solinoid that should activate before unit will start.
It would be helpful to know what fuse it is blowing, i.e if its the fuel pump fuse look in that system. if its the seat interlock fuse, look in that system.

Why would a mdl 1035 john deere tractor keep blowing the starter fuse

There is a distinct possibility that this tractor was originally equipped with a 6 volt system. If it has been upgraded to a 12 volt starter, the ignition will need to have a resistor installed to bring it back to 6 volts.
I could be all wrong on this but it's worth checking.

Why does the battery go dead overnight after john deere z425

Need additional information...Check to see if it is the new battery or the electrical system first........ when the battery is "up", disconnect from the system. Remove both wires from the battery...connect the next day and see if the battery will crank the mower. I've experienced new battery's that have an internal short....Let us know whether battery or John Deere electrical system.....and we can troubleshoot from there...
