TURN KEY BLOWS FUSE RIGHT AWAY

if the fuse blows right away when you turn the lights on or blows as soon as you put the key in and turn my car on, then you may have a dead short in the circuit.

you should ask a repair shop right away.

Sounds like a defective starter solenoid, if the key was the issue you would hear nothing.

Sounds like the starter is bad. Next time it does it hit the starter a few times with a hammer, if it starts right away replace the starter.

Which engine does the tractor have in it?
Actually it sounds more like the key switch itself. Try unplugging the connector from the back of the switch and look for corrosion, dirt build up etc in the plug. Plug and unplug it a couple of times, if there is corrosion on the contact points, this will usually cure it. Look for corrosion on both battery terminals and clean them if they are corroded, also check both for tightness especially the negative (ground) terminal.

try using it at a different location in the house(different circuit) if it also blows that fuse, there must be a short in the unit. do not use. if it works means line in the kitchen is overload, and you need a higher fuse rating or breaker.

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?

Check connections at battery cables,should be tight & not be able to move cables.Check for corrosion at battery terminals.Also I have seen problems at the inside fuse block where a terminal burns causing similar concerns as yours.Hope this helps

have your battery load tested at parts store
