Dynamometer testing antique tractors July 2023. Its fun being able to see the old tractors lug down and work while standing still. And its nice to get a horsepower value to compare to what the tractor left the factory with.
John Deere 70 D
Allis-Chalmers D14
John Deere 60
Massey Ferguson TO-35
John Deere AR
John Deere 430
John Deere G
John Deere R
We are testing at 4900 feet above sea level. I list the HP corrected for altitude using the approximation that for each 1000 feet in altitude you see a 3% decrease in HP. So at 4900, we estimate to see a 14.9% loss.

Best weather for a Dyno day is a cool damp misty day you'd be surprised the difference it makes 💪💪

Oh I'm sure it does. Just like ETs at the drag strip are so dependent on temperature and pressure.

Fascinating video. I like these dyno events. Im sorry to see that the G was sick.

Thanks! It will just be an excuse to dig into the engine!

Nice looking and running 70D std. I have three 70D, one is a std.

The 70 is one of our workhorses. It still gets used a lot.

Neat! I have a newer M&W dyno, does 540rpm pto, 1,000rpm PTO, and direct to engine. It sure is a great machine for testing tractors and tuning them.

Glad you think so!

Probably the altitude but the 70 can actually get their front wheels bouncing if you make them work that dyno

That'd be something to see!

I've got an unusual question, how much H.P. for the Pony motor ? A neighbor farmer had an R that vibrated everywhere.

@jonelsonster 6 ай бұрын

The pony motors are only like 20 cubic inches... So not much HP at all. But honestly, I don't know.

Was the transmissions in a one-to-one ratio gear.

@jonelsonster 10 ай бұрын

Are you taking about the transmission off the tractor or a transmission on the dyno?

@PaulCTownsend 10 ай бұрын

The Tractor I know nothing about your dyno:)

@parkersposts 5 ай бұрын

Doesn’t matter what gear the transmission is in. It’s a 540rpm pto dyno. So each model of tractor is geared down differently

Did you have your model M checked ? How about your model A ? Good video. Loved watching.

@jonelsonster 10 ай бұрын

We have tested my A a couple of years back and it did good. It was right at 35 HP. We did not test the M. Next time we have the Dyno out I'll have to test the M because I'd like to know it's power output too.
