How to adjusted Cutting Deck Belt Tension
You do not say which size cutting deck you have. I will be writing about the 48", 3 blade cutting deck
The belt on this deck is self tensioned. The tension is provided by a spring attached to a moveable pulley on the deck. When the belt is in place you can manually force this pulley forward/backward and it will release the tension.
If the belt is off track, place the belt back around all the pulleys in the correct path, lastly force this spring loaded pulley forward/backward (depending on your deck, the direction is not important, the tension is) to get the belt around the pulley. If the belt is placed correctly, when you release the spring loaded pulley it will properly tension the belt.
Typically, these belts should not be jumping off. If yours is coming off frequently the belt may be worn. When they wear they get quite a bit longer, then the tension pulley cannot apply the correct tension. Rarely does the tension spring have to be replaced.
The other problem that causes belt jumping is worn spindles and stationary pulleys. The spindles are the most likely to need replacement. You can buy excellent replacements for JD spindles on Amazon for very reasonable prices. The following spindles are super replacement spindles for the 48" deck. They may very well be the same for smaller and larger decks; I have not researched that. Just search Amazon for Silver Streak # 285851.

Yes. The ignition switch uses two contacts for start/run. START position energizes the fuel shutoff relay which feeds back into itself to create a self latching state. The RUN position allows the self latch to continue until no longer in the RUN position (OFF), which interrupts the self latch thereby cutting off fuel. So you need to determine why the ignition switch RUN position doesn't maintain the fuel relay self latch state.

There are several possible causes for this, such as:
A loose or disconnected spark plug wire
A faulty or dirty spark plug
A clogged or faulty fuel system
A broken or chafed wire from the starter
A bad voltage regulator or battery
A malfunctioning safety switch or ignition switch
You wll have to check each one of these, clean what is dirty, replace what is broken or clogged, make sure the spark gat is .76 mm if you change the plugs. You will need a multimeter to check the voltage regulator.
Disconnect the three-wire connector from the voltage regulator.
Connect the jumper wire from the negative battery terminal to the black wire terminal on the voltage regulator.
Connect the red probe of the multimeter to the red wire terminal on the voltage regulator, and the black probe to the jumper wire.
Set the multimeter to measure DC voltage and turn the ignition switch to the ON position. You should see a reading of about 12 volts. If not, the voltage regulator is faulty and needs to be replaced.
Turn the ignition switch to the OFF position and disconnect the multimeter and the jumper wire.
Reconnect the three-wire connector to the voltage regulator and the negative battery cable to the battery terminal.
It is probably a fluke unrelated to the reverse disengaging{the fact that it burnt off a cable}.If it has the original reverser still in place,the one that kicks it's self out and not the one that beeps at you,then it may need to be replaced.They usually didn'nt even make it all the way to the end of warranty before replacement was needed which is why they are now obsolete.for resolve this problem you can check service repair guide:
Likely a higher than normal impedance in the return path at the voltage regulator. The metal frame of the regulator is the return path via engine metal/block to battery negative. Make sure the regulator mounting screws are tight and free from corrosion.
If no problems found, further testing will be necessary to rule out a failing regulator. Comment for further assistance.
