Checking fluids on a new tractor is no joke!

I am so glad this initial panic went by without a truly bad experience.

Again, hydro fluid works in these front axles, but axle gear lube offers so much more protection for the hard work these front axles do with 4wd and FELs. Do give some thought to replacing the 10w20 sudt with a good quality 80w-90 or a 75w-90 semi-syn gear lube. It just isn't expensive and provides an additional level of peace of mind. My .02

Not disputing because I don't know. Questioning to learn new information. Why do you believe less expensive to buy gear oil does a better job than more expensive SUDT that factory uses? Isn't the purpose to just lubricate slow turning gears? I don't really know what's in the front axles that one lube over another would matter. Help me understand. I like to learn at least one new thing a day and hopefully more than one.

I believe it based on the fact that it is an axle. Like all axles, it has gears and bearings that require protection. While I have no objective eye witness to back me up, it is simply would seem easier to have an overhead gun to supply sudt to everything on the assembly line. SUDT works, so it's fine.

My manual states either gear lube or SUDT. So, again, either is fine. I am old school. I want gear lube in my truck diffs, boat motor lower units, and in my tractor's front 4wd axle. I do spend a few pennies more for the semi-syn 75w-90 just because I believe it has slightly better properties and slightly quicker flow rate than standard 80w-90.

I am sure some engineer type guys here can chime in. I know they have in the past and highly supported the idea that gear lube has superior properties over even the best universal type hydro fluids. My salesman strongly suggested doing this, as did the mechanic who set up my tractor and delivered it. I heard what they said and made a personal decision that I would do so as well. That's it. It is merely a personal choice.

I also would like to hear more about this from knowledgeable folks. I've seen this stated here a couple of times, but you never know if it's just internet chat getting repeated.

A quick search turned this up:

...looks good, I'll read it when I get some time later.

I know my manuals also say either one. I guess a truck and boat motor lower unit will be moving at high speed and a tractor never will. Also I'm thinking the front axle is being covered/bathed in the lubricant at all times so in my mind if my theory of being covered or bathed at all times, not sure I can see any difference in any lubricant or am I not understanding at all? Is the front axle submerged at all times in lubricant fluid?

JT, I think your thoughts are straight. Then we get down to the molecular level of lubrication, sheer, and stuff that makes my head ache.

All I know, it is a gear, shaft, seal, bearing contraption. Sudt is something akin to 10w-20. I am not sure that speed is the only issue. There are other stresses at work here. I just kick in my 4wd and feel a whole lot better that there is top quality, top of the line GEAR LUBE in there. There are no pumps or things of that nature. It's an axle. Thus, in my mind, axle fluid is in it.:thumbsup:

I grew up to the car world in the 60's. 60000 miles was nearing the life of a car and 100000 was unheard of. Oil was to be changed at 3000 miles. Panasonic was junk and a Datsun (now Nissan) was some kind of a car along with Toyota. Jump forward to 2009 and Panasonic, Nissan and Toyota are good products and can be upper end products. Car manuals say change oil at 4500 miles, 5000 miles and some 7500 miles and people talk about vehicles with 200000 and 300000 miles. Gorilla glue will hold forever. Tires last for 60000 miles. People talk on phones in cars. I still start cringing when a vehicle gets 40000 miles and expect it to die any day 60000 and I'm for sure not driving it out of town. 3000 miles between oil changes get me concerned but I have started stretching the changes out to 4000 to 4500 miles some times but sometimes it's still at 3000. Didn't believe in Motor Honey then and still don't. Do use splash of Power Service in the white bottle year round in my tractor fuel and always have even though I usually don't do any cold weather driving. Don't know why for sure but when I first started tractoring I was convinced, sort of, on a forum to do it, still do and still will. Guess there are some things that we have in our heads and it's just easier to keep them there than change them unless Jesus comes down and tells me to.
Appreciate your information and logic/reasoning behind your doing it. Always read your posts.

Go to your dealer and explain the issue, he'll give you the fluid for the front axle. I bet he'll even throw in the 50 hour service for free. I'd pull the drain plugs to see if it's totally dry. I'd also send an email to Kubota, getting the issue documented.

Upsetting, yes, end of the world, no.

I've purchased new Honda's that were not prepped right......

Thats the most professional way to address it.

I purchased my machine last year, it is a BX25. This thread prompted me to check my front axle fluid level, and I'm glad I did. Nothing showed on the dipstick, but I used a screwdriver and detected some fluid near the bottom. I only have 50 hours on the tractor, and none of it has been heavy use, so I don't think that damage was done. I promptly topped it off to make things right.

Thanks to all for the insight.

 

[Goodluck w/ That]

I would let the dealer know about it, if something breaks in the future because of lack of fluid they should replace it, it's their fault as far as I'm concerned. 10hrs, shouldn't have really hurt anything but would still make you mad!
