Holt H75 TRACTOR Engine!

So this means you’re making an RC tractor and miniature farm for it to work on right? 😄

Sounds like a mini top fuel dragster when cranked up

I think it's a gorgeous engine, I especially love the shrouded radiator and fan, as well as the centrifugal governor. Bit of a bummer that it was a rather shoddy build. Someone not mechanically inclined probably wouldn't have noticed the coolant issue and kept running that thing until the bearing surfaces were completely nuked. I kind of get it, these aren't built on a massive factory line. I imagine there aren't a lot of these built at all, so there are going to be cock-ups. That they used the wrong size o-rings, however, was a pretty big cock-up. Especially as these things aren't exactly cheap. That said, I kind of wish someone could get them to make a submarine diesel. I would be all over it like stink on poo if they did, lol...

I really appreciate that you let us enjoy your hobby with you by showing us all these beautiful model engines.

A toast to all the shell casings that left the industry to be cast in a new roll.

Cool engine. I like the big flywheel low speed revving!

mesmerizingly beautiful shots, thanks

I do enjoy the sound of these little engines. For some reason I'm imagining this engine being used to create a scale Armstead/Fordson Snow Motor screw drive tractor.

This is my favorite content to watch! Love your cinematic expertise!

One of the best sounding engines yet! seriously cool!

Давно смотрю твои видео, спасибо за интересные разработки!

So cute! Reminds me of a small puppy dog growling. Thanks for sharing.

A fast RC car is something we see all the time. RC Tractor Pulling thats something i would watch. Raw tork and heavy duty gearbox working to the max.

The tiny amount of valve lift is hilarious I need that camshaft for my small block race truck

Pretty close reproduction of the old Holt 75! Good catch on the cylinder sleeve o-rings! That could have been a really bad thing in short order. I'd love to see this running a small genset (i.e. a permanent magnet motor) and load it down with some lights and such. It would probably smooth right out with a load on it!😁

Fabulous video! Happy New Year

I dig the tractor flap on exhaust . way cool

Appears to be a number of fixes required for a new, out of the box, engine. Hopefully it wasn't too expensive.

I like most of your videos but this one is fantastic, one of my favorites

I love this farm engine it is the coolest engine I have ever seen. It also has a great sound to it. Love your channel and content. Always waiting for the next video. ❤🇨🇦
