Kubota Diesel Engine Battery CCA Requirement

[Furu]

I am posting this in the Kubota sub-forum as I think it is he best location to get good responses to my question.

I have a Kubota Engine (V2403) that is not in a tractor but I figure that someone with a similar sized engine in a tractor will have a good answer.
Basically if you have a Kubota tractor/engine with a horsepower around 45-55 it should get me a good idea. My engine (V2403) has 48.9 hp and I am beginning to question if the battery is undersized but have no similar Kubota engines and batteries to compare it to.

My issue is long going and does not seem to be ID'ed very accurately as to the exact problem by the equipment manufacturer and their engine reps. I am now starting to look and think outside the box. Yes my battery has been tested and passes with flying colors. Cables have been swapped and cleaned and a lot else as well.
I am not listing my battery CCA as I don't want to go down the path (yet) of posts saying "Oh that should be plenty" etc.
I just want to see what Kubota is putting into their similar diesel engine sized tractors.

If you could list the horsepower and the stock battery CCA of your Kubota tractor (if you fall in the 45-55 hp range) I would appreciate it. Maybe the Group size but that is not always representative of CCA.

Thanks

L3540-5740 CCA:582A, per manual. First 2 digits being the HP of the engine, basically

35 being the first two or 57 being the first two?
Or are these two different tractors?

My Kubota M6040 is listed at 62 engine horse power. The OEM battery is Group 31 and is rated at 900 cold crank amps.

Try this web site to obtain comparisons - - - Tractordata.com

From that web site - - Kubota L5040, 50 engine hp, OEM battery - 582 CCA

Because I'm located in a northern cold climate - last year I replaced the OEM battery with an Odyssey AGM battery.
The OEM battery is still fine - I just wanted the extra "OOMPH" of a larger AGM battery for winter use.
The new battery is Odyssey 31-PC2150 with 1150 CCA.

Nobody ever went wrong by installing the highest CCA battery that will fit into the battery compartment .

Yes but the area for the battery is not large and is sized for a group 70

Kubota 59 HP, put in an Optima Yellow Top 830 CCA

Yes, that is my philosophy too. I got bit once by the battery + - posts being on the opposite side/ends as the battery I was replacing, but was able to cut some tie wraps and get the cables to the other ends.

They spec the same battery for all models from the L3540 to the L5740 There is also 3940,4240,4740,5240 I believe
