Thanks so much for watching.

We've come a long way.

Thank you, glad you enjoyed.

Yep it's amazing how little work it took to get it running again.

Superb!

That's right, that's why they produce way more than rated power on good fuel.

taofledermaus! didnt expect you guys to be here!

They made fantastic machines, part science, part art.

Thanks, glad you enjoyed.

the rumley's wheels are wide enough to give damn good traction tbh btw why would it need a lowering kit when it's a fucking tractor that's low enough to the ground as it is?

besides, we don't want that thing to start turning the earth in the opposite direction.

+Michael Hartzell Here here.

+Michael Hartzell I think these were big 2 cylinder engines...that's why they have that hit and miss sound.

Military Chevy You are correct sir, although if it is running properly it shouldn't have the hit n miss tone.

*what tracks?*

Who knows, if only it could talk.

If it could talk I bet it can tell a fair few stories

The torque is real.

It's actually the radiator. The exhaust is fired through an ejector ring and blows out the top of the stack generating a current that draws cool air into the bottom of the box, through the radiator element and out the top of the chimney with the exhaust gasses. So the harder the engine works, the more exhaust it produces. The more exhaust produced, the more is fired out the top. The more fired out the top, the more cool air is drawn through the radiator to meet he increasing heat load put out by the engine working harder. It is a self regulating system. Brilliant. (Steam locomotives use a similar principal to fire exhaust steam from their cylinders up the stack and create a vacuum in the smokebox to pull fresh air into the firebox and through the tubes.)

Nailed it.

Poly Bun That's interesting. Thank you.

+slantfish65sd Watch out for the fence :)

+Rainhill1829 to heck with the fence I'll mow it down to still awesome tractor i love it

slantfish65sd Awesome.

These are indeed two cylinder, while some have an even firing rhythm due to both crank throws being inline, this model had them set at 180 degrees so it has the odd firing pattern much like the Deere engines.

Rainhill1829 Cool. Also, what's with the way the exhaust exits the top of rhe radiator? Do they try to use the exhaust jet to get some "blast pipe" effect to draw more fresh cooling air through the radiator tubes like the draught on a steam locomotive?

Nailed it, that is precisely what it's designed to do.

Yes, there is a crank bar on the backside of the flywheel which is used to start it normally, but we where just solving some ignition issues so we opted for the belt starter on this day.

Rainhill1829 ahh OK understandable even if she starts easy it's probably quite a workout, was a silly question now that I'm thinking about it....lol

Not silly at all, few folks know how these engines where started, especially considering these "big iron" units with their massive displacement engines.

svtirefire, yea they made those think good back in the day

The old Waterloo boys by John Deere had them too

Yeah its a surprisingly old tech.

Alex Mohler The carburetor, actually a glorified mixer valve, sits on top the cylinders just in front of the operators station. Usually there is an intake stack on top of it, but it is often removed while the engine is started so the operator can see down the mixer and choke it by hand if need be. the downside being if the engine backfires, you get it in the face if your not careful.

I see. Thank you for the explanation. I know that any of these older beasts and new ones too have NO mercy. All farm and industrial equipment demand respect. By the way you have the best videos out there.

Alex Mohler Oh, thank you so much.

That's too bad, hope you folks weathered the storms all right.

Robert Heinkel believe Florida flywheelers show has a few and a few steamers

The sound is totally normal, the gears are all spur cut and out in the open under the engine's cylinders. The transmission is an external sliding shaft two speed with reverse. The differential is enclosed in an oil bath like a modern unit. the clutch is a multi plate dry clutch inside the belt pulley.

Wow, thanks for all the information! So it's the transmission gears that are making the noise?

Yes indeed, the gears are strait or "spur" cut which tend to make a unique whining noise, especially when they are in the open (instead of the more modern and quieter helical cut gears).

Justin Vasko the transmission gears and some semi seized parts of the clutch make that metallic noise

@@alexhickey5633 it's a glorious noise.

Yes, it's quite normal, the gears in the transmission are spur cut and out in the open so they have a unique whine much like the reverse gear on some manual car transmissions.

I always used to think the same thingconstantly while watching old equipment...It’s taken me years to realize thats just how they sound. Gears weren’t angle cut to run smoother, and they really couldnt have cared less in the direction of sound-deadening texchnology.

Rainhill1829 I thought it was the clutch making that sound

9 inches diameter with an 11 inch stroke. So just imagine two ice cream pails moving back and forth in the cylinders. Pretty crazy huh.

If I remember right, it was a temporary clutch brake until the actual one was adjusted properly once again

Thank you i was wondering if it was to run in front and try to stop it under the wheel if it ran away lol

No worries, she had not run in a while and needed some adjustment.

Yeah, those gears kinda do sound like ducks.

I would have to check.

Mike La still looking for an engine

Yep, been there for decades.

Rainhill1829 and I'm not saying that's a bad thing it just caught my eye is all

Oh, not at all, it's neat to see all the repairs they pick up over their long lives.

Ahh *dismissive hand wave* what could go wrong 😜

Good ear, it is a Cockshutt 30 we use for belt starting machines. Reliable as a Swiss watch it is.

Something about the way those Rumelys burn fuel. Also, they clean up their combustion as they warm up, but the massive size of the engines means it takes a long time to get to that point, but they eventually stop smoking when fully warmed up.

Nailed it.

That's right, in many respects they where cutting edge.
