L3940 HSTC

That video is a hoot !

The L5240 starting is about exactly like my L5740 at 20 degrees, but that is no surprise since they have the same engine with the 5740 running an extra 100 rpm to get the additional power.

I wish The Fred would start a new thread to bring us up to date. Maybe the self-righteous types could stay off of the thread long enough for us to learn how the build turned out.

Edit: I see The Fred and I were posting at the same time. Thanks for the update, Fred. Sounds like it was a big success. My hat's off to you for your persistence and tenacity.

Right !!!! Hats off to The Fred !!!

The Fred,
I am so glad this turned out for you. Maybe you can start a thread called "I still Love my Tractor"? As one of the "believers" from the beginning, I really like seeing these pictures and like hearing that the turbo has made a positive difference. Maybe you can go into business selling kits. Haha. Good Job !!

Thanks all,


Feels like I added 25hp but no telling without checking it.

I'll check the cab to see if anything metal is close.

So far zero issues. Still does not start very well. Kept inside heated shop about 47 degrees. Let the glowplugs cycle once and it just doesn't start like my old Ciub Cadet left outdoors with a lower rad hose heater that I seldom use. That one starts down to 5 above witout plugging in.
My feeling is that if I left this 3940 outdoors it simply would not start below 30 above. Maybe it's me time will tell.

Nice video Fred, it's great to see it running and read about your satisfaction. You should consider slightly rebadging that machine: like L3940 SHO, L3940 SS, or maybe the F3940.

Fred,
I forget and I can't look it up due to the old thread being gone, but did you ever try it with new diesel?

He mentioned once that he did run some fresh diesel.

Ok it didn't show up that time, let's try this again.

Kubota L5240 Cold Start - YouTube

Holy smoke.. literally. I remember seeing another GL starting, and it was similar I think, but it's been a while. Next time I have the L3400 outside I'll do a cold start video, just for comparison. I don't understand what's so different about these engines, other than injection timing possibly. It's calling for cold temperatures here over the next little while, so I should be able to get a decent video.

Funny, after watching the above video there's another one on Youtube of an ALCO locomotive engine doing a cold start. We used to have some of these in gate vessels, starting was always impressive in cold weather. About the only thing worse was some of our ex-British submarine engines in cold weather with a water-cooled exhaust. Looked like Vesuvius boiling over and smelled like.. well, something truly foul.

I've only started my tractor down into the teens once, and I cycled the glow plugs twice instead of once, but it was nothing like that. It coughed for about two seconds and then ran fine. No smoke that I could see.

I should do a cold start video of my parents old B8200, it smokes for probably 30+ seconds but it is also a 25+ year old tractor. I really think if the timing was bumped up a few degrees on these egr engine the smoke on a cold start would disappear.

It has to have something to do with the way these things are set up, our L5740 is like everyone else s, but out L5030 didn't smoke nearly as much and started much smoother.
