Why does JD put the key where they do? Keys are dime a dozen, but when you can not get the broken key out it becomes an issue. When you forget it just once, snap!!! No more for me. !!!!! I ended up not being able to get one out so I got an aftermarket switch. Didn't even check OEM price! I wonder why? It has been a great machine overall. I cannot imagine I am the only one that breaks the key. It is somewhat congested under the shroud. Hindsight, I should have looked closer to maybe put, the new switch where the light switch is, and put the light switch elsewhere. I think there would have been enough room for the switch and the connector there. If considering this for yourself beware of the amount of room needed for the switch and plug, once the plastic shroud is where it should be.

You might not ever break off another key, but where you mounted that is going to be a constant source of moisture contamination forever.

It has a light coat of clear silicone all around it, and where the key goes in. Not inside, just around key to switch

The vertical keyhole is the problem, not the mounting hole You can't seal that.
You only read part of it, but that's ok. I will take my chances. I think if we can put a man on the moon I can seal that. Of your 2,000 plus posts, I bet a high percentage finds fault. No need to respond back, please just keep scrolling to another

I agree with Harry you may not break another key off but I'll bet keeping moisture out of inside of switch will be difficult unless tractor is stored under a cover.

In the 27 years of my 4300, don't recall ever even bumping the key where it is located. But doesn't mean it can't happen.
Where you have mounted it, not a problem if kept inside out of the weather.

Typically key switches located like that will use a plastic "umbrella" molded onto the key that fits over the switch to keep water out. Without that, the switches have a tendency to fail pretty quick if out in the weather.

Might see if you can find a key like that for your switch.

I eliminated the key switch entirely on my Kubota's. Replaced the key switch with 2 push to contact buttons. One for the glow plugs and one for the starter solenoid.

Don't get concerned about theft at all as they are insured for ACV and kept in the barn anyway.

Ain't knockin your knees on it up there!! Good job but yeah, I'd get an umbrella key.
My tractor has the switches and engine shut off in the absolute worst places also.
Or my knees are. :unsure:

Put a slit in a plastic bottle cap the right size to shield the switch and seal the key with silicone. The Key could be a pretty darn tight fit through the plastic cap.

I like momentary push button capped with the rubber boot for the starter solenoid. With a separate Button for glow plugs.

Today's Key switches are junk overall from overseas.
Buy a 69 Ford truck ignition switch, (old stock)
Start Buttons built for industrial machinery are beefy.
Keys are for honest people. If someone wants your tractor a couple jumper wires will start it. I like start buttons; you can add a separate main battery disconnect but that adds another source for bad connections.

I leave keys in the ignition until the break then use buttons.
People that know me know what I would do to a thief. I'm not a playing tough guy but I would hurt a thief. I know consequences!

Put Vaseline on the face of your switch. Put some silicone inside a plastic cap with your key centered through. (tight fit)
Put the key in the switch and let it sit for a few days.
The Vaseline won't let the silicon stick to the switch face. Turn the key and the plastic cap together to relieve any sticking the first turn.
You will have a custom shaped sealed key.

Trim any silicone that ozzed around the cap and paint.

I understand and respect Harry's point, but that switch can be sealed
Or buy the umbrella key shown.
For the OP the key annoyed him. He made a change to suit his needs.

My suggestion may be Apollo 13 or half ### but would work.
