That does sound crazy. Was taught in A&P school that at least two or three threads need to come through the nut for proper torque. Who's right?Per ASTM, 2 threads in the nut will hold the shear strength of the bolt. Not sure I would agree either, but if Kubota can save $.03/bolt……I prefer to see at least 2 threads sticking out of the nut. My experience in MV switchgear has never been pleasant with short bolts.
There are two strengths for a bolt. The shear strength is when it is being loaded ”sideways“ like it is a pin. In that case you are trying to cut the bolt into two (or three) pieces. The nut is simply acting like a pin or circlip to hold it in place as it is being cut. That is what the post shows where this discussion started.That does sound crazy.

Paging runs with scissors!
You didn’t get the picture to post. I think you need five posts before you can put in a photo.Well, new here to the site… I’m looking at my L3901 that is partially submerged under water due to the flooding in SC on the Edisto River!!! It’s fresh water but I’m debating on cranking it and moving it until the water goes down. I can’t find any information on max fording through water. Thanks for any advice and this is a great site!!!
It is up to the axles but not up to the air inlet. I was a little worried because hydraulic filter and oil filer are partially submerged. River crested last night and is going down. Still might just wait.You didn’t get the picture to post. I think you need five posts before you can put in a photo.
But if the water was above the air filter inlet DO NOT try to crank the engine!
if it was up to the axles and still sitting in the water I would move it out of the water under its own power or pull it out is probably best.

Note that the picture in their article shows a typical bolt with threads that are not complete for nearly two threads.There are two strengths for a bolt. The shear strength is when it is being loaded ”sideways“ like it is a pin. In that case you are trying to cut the bolt into two (or three) pieces. The nut is simply acting like a pin or circlip to hold it in place as it is being cut. That is what the post shows where this discussion started.
The second strength is in tension (pulling the head) and does require the full nut engagement with a couple of extra threads to get the full tensile bolt strength.
For simplicity most people are taught that ALL bolts must go through the nut. And that is best in both conditions and easier to always do the same thing.
Here is a link to more information if you are interested
We have been miserable for you! Lol!!Picked up 225 bales this afternoon. Here in S Indiana, we've had 4 days of incredible weather for August. Low to mid 80s and low humidity. Normally we are in mid 90s and high humidity, making it miserable.
Picking up hay was fun!

It is the white bares that steal the corn in these parts of the woods.I understand the problem.
I would grow some sweet corn,......and the coons would eat it the day before I was ready to pick.

Don't even think about starting it because you can do more damage to the tractor than the water will have done. See if you can get a neighbor to pull it out with a large tractor, or have a tow company come to the site with a roll-back truck with a good winch. Have it winched out and onto the back of the rollback. Bring it to your driveway, and pressure wash all the silt off of the tractor first. You might have to wipe it with a cloth and some Dawn dishwashing liquid to get it clean. If you have insurance on the tractor, take lots of pictures as you clean and before it is moved. Only when it is fully cleaned, carefully wipe around all the dipsticks and check the fluid levels. If they are high there is water inside the cavity. Consult with your dealer before doing anything else. If you have insurance the insurance company will tell you what to do. It might be a total loss, or they might pay to have the dealer service it. If there is no insurance, then come back to this site, and the Kubota knowledgeable people will give you instructions on how to proceed so you don't do any damage to the engine or transmission. I know that you are anxious to get started on getting the tractor running, but in your haste, you might be costing yourself thousands of dollars worth of damage. Learn from others mistakes that have done the wrong thing when their tractor has overturned or wound up in water.It is up to the axles but not up to the air inlet.

We've had several days of great August weather down here in the mid-South also. Not quite good enough to inspire hay hauling, though.Picked up 225 bales this afternoon.

While i dont know your model specifically....As long as it hasn't hit the oil fill/ dipstick level in the engine, you should be good there. Same goes for the transmission and hydraulics. If it wasn't leaking oil to begin with, the submerged filters won't let water in. The front axle oil should be changed if it is 4wd. The axle was probably underwater.It is up to the axles but not up to the air inlet. I was a little worried because hydraulic filter and oil filer are partially submerged.
