This leak is getting worse with continued use with tractor. Drip is falling from behind radiator area, but it may being blown to that point from fan? Anyone got any ideas?

Watch this video.

Others had the correct answer, but you had the video! Showed me where to look and I fixed it in 5 minutes! Comparing that with transporting to a dealer I trust(120 mile trip) proabably having to leave,return trip to pickup, at least it was under wararenty, couple days no tractor(we always need our tractor) Thank you thank you

The down side to this type of owner self fix is there is no feedback to the OEM or cost of poor quality to get Corp eyes on it.

bottom line is they don’t know they’re having an issue that needs resolved.

it’s still hard to believe they don’t use constant force clamps. There’s a reason why automotive OEM’s use them.

I’m glad it was something simple and didn’t require the OP further stress or cost.

Constant tension clamps only work well on low-pressure systems such as cooling-systems. Automotive OEMs should use screw-type clamps or swaged fittings on high-pressure systems such as oil, lubrication, and hydraulics.

I agree with the failure to provide OEM feedback comment. On my RTV-X900 I discovered a leaking hose-to-pipe connection in the coolant system which was dripping. I removed the hose and cleaned the pipe and re-clamped the hose. Those guys over in Georgia who assembled (they call it “manufactured” these days) do not know they left this clamp under-torqued.

they use cheap clamps to help keep the cost down

if the deere version of the (mostly) same tractor is $100 less than Kubota, do you think Kubota's gonna be ok with that knowing that their customers are going to get a green tractor for less money? No, they're going to cut a cost somewhere, or in a lot of areas, to get that cost down.

that is what manufacturing is about. Build a good product as cheap as possible, yet still be able to market it and sell it for enough $$$ to pay the bills. It is not easy.

About to get worse, much worse than before and it won't be long either.

I noticed my tractor dripping there yesterday. When I opened the hood I found a mouse nest right under the cooler, so I assumed that a mouse chewed through a hose. Before I started tearing into I figured I better check here. I'm glad I did! hopefully it is just a loose clamp like everyone else had.

Turns out that is the correct hose and the clamps were loose. But the hose is deteriorated. Trimming the end and repositioning has the leak stopped for now. But It will need a new hose. The machine is only a year 1/2 old. They could have used a better hose! Anyone happen to know the part number?
