Wow. Just happened upon this thread. My 03 BX2200 starter has had similar issues. Just thought it was getting bad but after a tear down, cleaning and dressing up the contactors the issue is still there on occasion.
I will give Mr. kubmech's fix a try. Even if low voltage is not the problem now it may well be in the near future.
Thanks Mr. kubmech.

Kubota l4200. Though for sure the John Deere relay kit would fix it but still get the same issue. turn key, click or slow crank and nothing. Thinking it must be the starter selenoid but I'm unsure how to pinpoint that before taking the starter off. Any suggestions?
thanks

Thought I would add pictures to my original Post, but am unable to edit.
Relay mounted to alternator bolt:
Relay wiring:
I was also curious if the safety switches would be bypassed using the JD relay kit.
The gear lever (hydro transmission) still needs to be in the neutral position.
The PTO lever still needs to be in the disconnect position.
But I no longer have to depress the clutch pedal to start the engine.

Today I installed the John Deere relay kit on a Kubota TG 1860 and it has solved starting problems I have had for 10 years. The part costs $35 today. I really like the tractor but the Kubota dealer has looked at it multiple times and could never fix this starting issue. They just kept replacing the relay, battery, starter, etc...generating many large repair bills but never fixing the problem for more than a couple days. Thanks so much to Kubmech for the exact part and directions. I fixed this issue on my own in 15 mins.

I appreciate the good photos that several have included. Add my 17 year old B2100 to the list of "starting like brand new" tractors. I procrastinated this to death - read about it a couple years ago, bought the relay last fall and FINALLY installed it 2 days ago. Not one starting miss since then. My grandson was impressed that I fixed the tractor, but is glad that he no longer has to bump the key a few times to get her going. Thanks to all!

Here's a direct link for the instruction's in pdf format, the pics are a little off but at the end of the pdf, there's a schematic diagram that may help some.

Just adding this from very original post:
AM107421. It's prewired and comes with instructions.
Basically the way it works is...
The red wire goes to the Battery terminal of the starter.
The black wire goes to ground.
You plug the black/white lead that would normally go to your starter to the male purple connector of the relay.
The female connector purple lead to the starter.

This thread was extremely helpful to me! Thanks for everyone who has posted this info here! I figured that since you all helped me solve this problem, I can do my part to add to this post.
My B2400 had this very same problem.....turn the key and all you get is a click.....no start. After finding this post, I called up my local JD dealer and asked if they have the relay kit in stock. They did, so I made the trip over to pick it up. I'm looking at this relay and it looks to me like a standard 12v relay....I build cars for a living and I use relays exactly like this on a daily basis. I ask the parts guy....."is there anything special about this relay or is this a standard 12v relay?" The parts guy says that there is nothing at all special about it.....just a standard 12v relay. It's not even a weatherpack relay.....it's just like this one:
VIAIR 4 Amp Relay-9394 - The Home Depot
You can buy this same style of relay from home depot, ebay, radio shack or your local parts store for under $5. JD was going to charge me $37 plus tax. I already had dozens of these type of relay on the shelf in my shop, so I grabbed one and installed it this morning. Instant fix to the problem. The problem was getting really bad to the point that it was taking 5 to 10 turns of the key and getting "clicks" before I could get it to crank every time I went to start the tractor. I installed the relay first thing this morning and used the tractor all day today....probably starting the tractor a dozen times or so and it never missed a beat once. The starter solenoid pulls quite a bit of current.....which is why resistance in that circuit causes the voltage to be low at the starter solenoid. Remove the current draw and you will still have 12 volts there. That is what the relay does.....removes the current draw in that circuit. Instead of the starter solenoid drawing...say.....5 amps, the relay coil that closes the relay only draws about 0.2 amp. This is why the relay fixes the problem. Calling it a "low voltage relay" is not really accurate. It's just a standard relay that fixes a low voltage problem caused by high current draw.
All of these relays have the terminals labeled 85, 86, 30, 87.....and if it's a 5 post relay instead of just 4 (either will work) you will have a center terminal labeled 87a (which is not used). You would disconnect the solenoid wire and attach it to 85. Attach 86 to ground. Attach 30 to the main starter battery cable. Attach 87 to the starter solenoid.

Hey Kubota guys: why not ask the admin to make this thread a 'sticky' for the Kubota Owning/operating forum? This way it's permanently there for all to refer to at the top of the forum's opening page?
Then anyone looking for a starting issue fix for their 'bota would likely see it before it disappears again into the thread chaos that eventually takes over most forums on TBN...
