Edward Jonez Doubtful

That's not doubtful at all

@@lukethedrifter3363 More power in the fuel back in the day.

I built an 820 with newer taller pistons advanced cam timing and the later pumps and injectors that was over a 100hp

@@leonardcollings7389 YES. BETTER FUEL IS PART OF THE REASON. SULPHUR HAS A GOOD DEAL OF LATENT ENERGY. THAT HAS ALL BEEN REMOVED TO HELP WITH EMISSIONS. AS CHAD GILLESPIE STATED BELOW HE HAS SEEN THEM MAKE OVER 100HP. DON MEEKER IN OHIO BUILT AN 830 THAT HAS BEEN TURNED UP, TWISTED AND TURBOED. 5 YEARS AGO I SAW IT MAKE 135.2 ON A CERTIFIED DYNO AT A FAIRGROUNDS IN INDIANA.

Because that's all it has!

It only had 2 cylinders!

@@countrygent4 That's the joke.

@@James_Hough John Deere has not built a 2 cylinder tractor for the US market for 60 yrs. Lots of people do not even remember those tractors so don't make a remark that stupid.

@@countrygent4 ...and the John Deere 830 only has 2 cylinders. IT WAS A JOKE

Russell Ehler They have mechanical injectors,so that's not possible for starters.

Yes, they have mechanical injectors. And on the injection pump, there is a screw which permits you to adjust the amount fuel the pump sends to the injector. You can turn it up quite a bit, or turn it down. My motor puts out better numbers than factory spec, so I have never messed with it. I did turn up the injection on my 70D and picked up a few horsepower on it and smoke.

Back about 2010 there was a 830 out of Marshall, Il that pulled around Illinois with so much fuel turned on that it would stretch the head bolts every pull so they built a frame around the head bolts and it came back to the frame and it stopped stretching the head bolts. I saw it pull one afternoon in Butler, Ill in the 6500, 7500 and 8500 lb class and made a full pull in every class.

Blowing black smoke, fuel isn't the issue.

​@@om617yota8yes it is its a rich afr

There are U-tube vidoes with John Deere 2 cylinder tractors with 2 & 3 turbos on them. The horsepower was out of this world.

"Juan Vanado"

Me toco trabajar muchos años con esos tractores son super fuertes y ademas muy eficientes en el combustible

A mi conocimiento esta mal la medicion no puede registrar 75hp el jd830 porque el jd 730 tiene esa potencia y comprobado por muchos aca en argentina el 730 siempre trabajo con arado de 6discos de 26pulgadas a 10cmts de profundidad y lo hace sin ningun esfuerzo se supone que el 830 es mas grande de motor. La verdad me deja muchas dudas la medicion..

@@victoribarra3023 85 HP tiene el 830..

@@andresguzman6648 tiene mas logica 85 hp y a un bajo regimen de vueltas de estos motores tienen un torque impresionante .lastima que en argentina ya no queda ninguno fueron importados muy pocos.

I put in a new head gasket. Otherwise stock as a stove.

I would think that the flow of exhaust gasses would be too erratic. But that’s just my guess.

There is a video where two guys put turbo's on 70 Diesel and took the governor off or something because it was turning way over 1100 Rpm's.

I think a lot of those PTO dynos are pretty simplistic compared to automotive ones. It may not even measure that.

There testing pto power he's probably getting close to 90 on the belt.

jd1950r yeah I figured he'd be making more beings it's turned up like that

It's a Dyno to test the Horsepower they hook the rear pto to a shaft that is freely spinning and they put load on the shaft which causes the engine to work harder and causes it to blow black smoke

You don't diesel much do you?

Who cares what she thinks!

Remember the fuel has been changed. Today's fuel has way less power in it.

"Modern" cheap fuel.

Russell Ehler Actually the diesel fuel today is much better than years ago. Diesel back than was no.2 fuel oil, today's premium diesel makes much more power and less smoke than no.2
