Remember pony motors?

That's all they had back when I worked in the woods. 2 minute video

I have an old d6 9u with a pony motor on my property. It belongs to a friend of mine but it sits at my place and I fire it up and run whenever I want. That little pony motor is a loud sob.

Yup!

Even the Pony Motors Could Be a Bittch!

Did You Pipe It Soj?

No muffler on it if that’s what you mean. The pony exhaust runs through the diesel intake then straight pipe out.

I ran D6 with a pony motor for half a summer, then got promoted to the D7 for road work and deep chiseling.

I miss those days.

Nothing ruins a nice peaceful quiet morning more than starting up a pony motor. Saddle up men!

Hell, we had an old D9 where I worked and when you started it up neighbors a mile away thought there was a fire. These kids rolling coal have nothing on the old D9.

In cold weather it took forever just to get the pony started...what a pain ! That was back when men were men and everybody else drank Schlitz ( Bud Light predecessor} ! The steering brake/clutch was another real piece of work. The old cable control units were pretty primitive too.

I’ve got a TD9.

littlebull209338 · Jul 4, 2023

A TD9 is a rare dozer. The TD 15B, 20C & 25C were very good.

Ok, you are all starting to age yourself. ??

They’d pay you to knock a hole in the block of that Diesel engine

I dug through some of my old photos trying to find one of a Cat and this is the only one I have. It has a C-frame instead of a blade. Towing an arch to better handle the big logs. About 1970.

Father in law use to have an old D2 with cable operated blade.

Small engine that starts a big engine. No electric starter motor.

And the pony was started by pull cord or crank. Had to get your morning exercise some how?

Reuben_Soady · Jul 5, 2023

Got it. I grew up driving (and blowing soot from) a diesel station wagon in MN. Learned the difference between #1 and #2 pretty quick. Only ponies we had were kegs, though (city boy).

littlebull209338 · Jul 5, 2023

Did you guys notice that the pony motor in the video had an electric start ? That's cheating

A "pony motor" is a small gasoline engine that is used to warm up a big diesel engine. The heat from the pony motor helps the diesel attain starting temperature. Once the diesel is warm enough, the operator starts the diesel engine and turns off the gasoline engine. The pony motor is "clutched" into the primary engine, the diesel, and in turn, the diesel is set in motion 1.

We had an old John Deere 720 diesel ag tractor back in the day that started with a pony motor. It was an art to get that hunk of iron started. That tractor was noisy as hell and had a clank in the drivetrain that would make you deaf. I can remember more than once, one of us kids firing it up with the pony motor and forgetting to shut the pony off when the real, 2 lunger took off. Usually, the pony would run out of gas before anyone got caught. But I remember one time seeing my pissed off dad walking at a brisk pace across the field waving his arms to get my attention. He finally got me to stop and just walked up, flipped the switch off on the pony giving me a dirty look, turning and walking away before he lost his cool.

Ours was a tricycle front end

I can't remember, was that a 'poppin' Johnny?

It didn't pop quite like the old gas model A or B but with only 2 cylinders, it's still had that sound even if it was a diesel. The 720 diesel came out around 1957 I believe.
