Fuel on angles

[Shadow_storm56]

Just a curiosity questions, my new m5n-091 is great but if it's at 1/4 of a tank of fuel or less it will run out of fuel when tilted left. Not a big deal but is this a common kubota thing?

Had to look up that model number. Thought you were referring to a lawn mower.

Never experienced that with either of my small Kubota tractors. Cannot imagine that should be normal with your m5n-091.

Hopefully someone with some real knowledge will give a more useful answer...sounds like the fuel comes out of the tank on the right side, and when you tilt left the fuel at the outlet point goes to zero.

How much are you tilting the tractor to the left when this happens? Probably important info to help those with the knowledge to answer your question.

Only happend once sofar, our orchards are steep side hills so fairly Strong tilt.

curious was I, went to kubparts and it makes perfect sense ! 2 tanks, left and right but only fed from the right tank, so get it higher than the lef, it'll drain into the left tank and NO fuel to the engine.
very 'silly' design..sure glad small planes ain't plumbed that way !!!

I think it has to do with lowering the center of gravity and keeping it balanced. I feel like it should pickup from both tanks somhow but if this is my only issue ill be fine.

The 3560 has 2 tanks, but I have concluded that you can’t really believe the fuel gauge.

 

[GreensvilleJay]

Looking at the parts diagrams, it'd be a 'slamdunk' to T the outlets into one and ELIMINATE the 'no fuel' problem......

I was supposing the odd circulation has to do with fuel cooling.

I honestly don't find new machines of any type read accurate fuel levels.

3 bars on the digital display on my LX, I know it will hold all of 5 gallons. Ready for the next can now. I don't use enough to worry about running out, and the closest (not necessarily the cheapest) diesel is only about 2 miles away.

Better than the stick-o-meter we used on the old 8N or the Cub Farm-all.

I'm not so sure about that.
You'd still have the fuel migration to the downhill tank and would still suck air from the uphill tank.

Cant speak for that model exactly, but the GL60 have two tanks as previously said. The fuel pickup is in the left side tank. The cross/joiner tube has a one way baffle on the entrance to the left tank. In other words it should migrate to the left tank and stay there from the right tank. If you stayed on a hill in a low tank fill position for long periods of time, I could see how you would still run low. Assuming the baffle is working as it should. If the baffle isn't working it would expedite the starvation.

I was pushing out brush so like 5 mins at the angle.

How so??

 

[GreensvilleJay]

from the diagram ONLY the right tank feeds the filter-pump-engine
adding a 'T' allows the left tank to also feed the beast
should never 'suck air' as one tank always has fuel in it.

I just looked up the m5n-91 and it looks like it only has one driver side tank.... Sound right OP?
If so, then forget all the talk of dual tanks... It pulls fuel from the bottom of the tank as molded, not through the top as most cars are. You may just be out of luck then for the hill endeavors if less than half tank.. The drawing does not show which side it favors on the bottom, but whichever it is on yours when you look at it will be the tilt side it will drive the longest on. Probably right hand leans.

It's under the cab, not on the left or right side is right across. Pickup is on the right though.

The stick-o-meter is always accurate and if it breaks, it’s a pretty easy fix so long as it doesn’t end up lost in the tank.

I have gotten a little spoiled with a real gauge on the Kubota.

this... M5N-091HD12 is the 1st of about 8 versions of the M5N-091 listed in the Canadian Kubota Parts website. I didn't bother looking at the other 6 or 7....
it clearly shows TWO tanks, LH, RH and the connecting 'plumbing'.
Maybe the USA version of that tractor is different ?
What I do see .based on the drawings , is that it is easy to be starved of fuel,given the right tilt and level of fuel, as it'll drain into the lower tank. Having a second 'feed' from the bottom of the 'lower' tank would ensure the engine always has a constant supply of fuel.

I missed the fact your in Canada, the diagrams for the U.S. version appear to have one tank.
