New Kubota Corrosion

[Mot]

You could try Penetrol. It is like a thin varnish that will give some protection yet not interfere with threads or gum things up like paint. Home Depot has it. It is good for a lot of other things too.

And it goes on like water...

Check your electrical connections. Maybe a bad connection is causing galvanic corrosion?

I don't know what environment you've run it in, or how you store it, but I can say if I got a new Kubota and it did that, with the price increases they have done over the last two years.....they'd be taking it back.

I really appreciate all the feedback. I use fluid film on my truck as it see road salt, but I wouldn't think I'd need it on the tractor since it stays here. I'll talk with the dealer, but I have little faith. I've only washed with simple car wash, turtle wax brand i think. Most of the fittings didn't get a good scrub, due to there geometry and locations, so I'm thinking these parts we pretty coated from shipment.. and then repeated moisture due to the thaw this spring started reacting with any salt film on the parts. I keep a JD zero turn and a few dirt bikes in the same space.. none have these issues. Here is the flail mower stored in the same exact space... zero corrosion issues on the plated parts. I'll take a look a penetrol.

Try parking indoors in a heated garage

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

Really, are you real ?? Now you're blaming the owner, a tractor is supposed to be made to stay outside, where do you use a tractor? Outside not inside of a heating garage. Where do dealers keep their tractors until they're sold??

Do they use salt on your road and you snow blow end of driveway?

They don't use salt on my road and my Kubota and implements still look like new.

But friends that live in city have lots of rust on their machines of all brands.

Do any of your neighbors have Kubota equipment? Any of them seeing the same issues?

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!

Seems to me it’s a problem with the materials used by the company that makes fittings for Kubota (Jis, from what I understand) and ultimately the responsibility of Kubota to make good on it. I would hope that Kubota would stand behind their product.

I don't salt my driveway... and don't currently use the tractor to plow. It sat all winter. I gave the dealer a call and sent them the same photos. We'll see. Looks like I'll start coating everything going forward.

"they'd be taking it back." Such a dumb comment.
