New Kubota Corrosion

[ultrarunner]

Environment?

My oldest Kubota is 20 years old and no rust or corrosion...

It generally tends to be on the dusty dry side of things climate wise much if the year.

Years ago we had a new car with lots of corrosion and it had never been in snow country.

Turns out the ship it was on went through a very bad Typhon nearly sinking.

Turns out it was not the only one delivered having survived days of bathing in brine...

Clearly that is not common. I've never seen it. Our Kubota sits outside for 15 years now and doesn't show that. It looks like salt. Lots of flooding these days, and auctions of flood-saturated equipment.

Tractors have plenty of electrical contacts & sensors that are not obvious. I'd have someone - probably a dealer - take off the dash while you are on hand to document any corrosion there.

If so, get some Kubota insurance at the least. I would also talk to them about who pays for any problems.

Try parking indoors in a heated garage

Look at the condensation on your painted steel...this is an owner issue, not a K issue

Half the winter it was in my car garage, other half in the barn which is completely covered but subject to air movement. My concern is that even properly plated steel shouldn’t corrode like this. My guess is bad plating on the fittings. If paint holds up fine, shouldn’t a plated hydraulic fitting? It’s certainly gets less water cycles than a tractor uncovered in the open.

I’m about 13 miles to the coast line.

Anybody know if Kubota warranty will consider this?

If you have a central air conditioning unit or heat pump remove one of the panels on the compressor housing and see if the compressor condenser is showing the same corrosion. You will then know if your local air is causing the problem.

PLEASE DO NOT USE STEEL WOOL! Doing so will only damage the existing plating on those components!! I agree that corrosion looks excessive but it’s not beyond salvage!
Get some “Fluid Film”. I prefer the paste over the spray, but spray will work too. Coat everything you can see with that stuff and Viola’ you’re good! I call it Sheep Snot! It’s pure lanolin. Wife hates the smell, I find it…..arousing….

Welcome to the forum! Good people and good information here!

Cheers,

That sure looks like salt or some other kind of chemical corrosion. I’ve never seen or experienced this with my machines. It sure seems like your machine was exposed to something before you bought it. I would be investigating a warranty claim if you haven’t subjected it to any chemicals.

Best idea I've heard all day. Compare it with other machines on your property. Look under the hood of your car. Where ever.... & take some photos so we can see, too.

Try and get some ACF-50 from Amazon and spray on your surfaces you want protected. From the aerospace industry to protect planes.......good stuff.

Hello All, I have been reading a learning a ton on this site. Thank you to all who contribute.

I have a 1 year old Kubota 4760, 2022 model delivered in May of 2023. I am appauled by the corrosion on all the silver plated hardware. The tractor has 55 hours on it, and is kept either in my garage or under a 3-sided barn, it does not see the rain/snow. It stays on my property and gets washed a few times a year. I live in southern New Hampshire, not by the beach. It appears that just condensation has corroded every single plated fitting/hardware item. I have a BH92 on this as well, and all the silver connectors, even hose clamps, are corroded. Am I just expecting too much?

Some of the fittings say China right on them. I'm dissapointed and will now go and try to steelwool/oil all the parts, but what a waste of time. Here are pictures of the hydro connections for the FEL, under the cab and for 3rd funtion valve. I took these pictures a few weeks ago, on a warm morning. You can see some droplets from the humid air on the cold metal. Notice on the middle picture on the cab, some connections have zero corrosion, but most have the oxidation. I really expected more for the money spent on this. Any thoughts or insite? Thanks!

I have the same issue on a 2 year old Kubota 4760. It has never been left outside and is always kept inside. If you find anything out or how to prevent this, please let me know.

I doubt most those of parts are kubota. Probably ansung.
