Antique Tractor Dyno Testing

Описание к видео Antique Tractor Dyno Testing

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.

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.
