Right between the frame rails at the front lower grille area, slightly to the left . Your operators manual covers this.

I have recently purchased my first tractor. It is a Kubota L2000. It is in great shape other than the brakes ( they are somewhat weak on stopping power). I was wondering if there is a u.s made comparable model that is the same as the “grey market” tractor i purchased (without knowing the trouble it would be finding info on it). I want to keep it serviced but don’t even know what i’m looking at! A service manual with diagrams, specs and fluid recomendations would be great if I could find one. Any ideas on what u.s model is the same as the L2000? Perhaps i could find a used manual on it. Thanks, Great site! Mike

I should also have added that on hydrostatic tractors, there may be a second cooler for the transmission oil that also needs to be kept clean.

Great article – I hope you do not mind me adding my thoughts and experiences – although based on my European specification B1750, I think some may be valid to US readers too.

You state that the fine filter is in front of the radiator. Mine isn’t – it is behind the radiator.

I think it is a case of blowers and suckers. Cars, for example, suck air through the radiator – the air comes in the front, goes through the radiator then over engine. When moving, the engine fan which is behind the radiator is not required (so is often electric or viscous coupled) as the air flows through with the movement of the car and a fan is not necessary.

Kubotas (or at least my B1750) do not do these sorts of speeds and are what I term blowers. The fan is direct driven off the engine, but more important it works the other way, Air is pulled over engine (thus cooling it) then blown forwards through the radiator. The fine mesh is thus behind the radiator. I think Caterpillar crawlers are similar.

I suppose the point is to blow through the radiator to clear any debris in the fins, the air jet should be in opposite direction to that of normal flow – so the debris goes back out the side it came. So, for my B1750 you blow from front of tractor, not the engine side as the article suggests.

One other thing – I try and clean the fine filter off first with an industrial vacuum cleaner rather than using an air jet – I like the idea of sucking the debris up and capturing it rather than blowing it everywhere then breathing it in. Just me.

I can confirm that the blocked fine filters will cause overheating if not kept clean! And it invariably happens when you are furthest from workshop / top-up water.

Regards,

Julian

Just like Elvis. “Hang Loose”!”

My L3130 has been stalling when I put it in gear. I have changed all the fluids and filters, checked the coolant and added injector adn carb cleaner.

I notice there are two tubes going into the coolant overflow bottle. One hangs loose, connected to the bottle on one end and nothing else on the other. Is it supposed to connect to something or is it supposed to hang loose?

Hey there AK,

Thank you for taking the time to post a comment and glad to hear that our fuel line bleeding video and article helped you out a bit. Regarding additional videos for changing transmission, front drive and steering box fluids – a great idea!

The next time we setup for filming, we will cover off how to change these fluids as you suggest. I’ll write you a quick email to let you know that we have some new content. Thanks for the suggestion! Much appreciated.

Mr. K

Good Stuff, I recently bought a B6100DT and your fuel bleeding article came in very handy when I ran the tractor out of fuel. The manual is good but comes no where near what you give us in your videos/articles.

I am changing all the filters and fluids. Would do a video and article on changing the transmission and front wheel drive fluids? Also, the steering box?

Thanks and much appreciated!
