As usual your walk around is spot on! We were fortunate enough to speak with the owners of this tractor. The original owners had removed most of the components off of the top including the engine. It was converted into a mobile grain bin trailer. The original pictures he showed us were quite interesting. This is one of only three tractors still known in existence. This is the only one that is operational. The engine block was completely recast after 3D scanning one of the other existing tractors. Only the crankshaft is an original engine component. Just like you noticed, most things had to be meticulously remade. The owner told us that the oil system was very rudimentary. It relied on a splash / slinger system that shot oil into cups to carry it to the top of the motor. Needless to say it caused most of these engines to fail prematurely. That is why the cam and other upper components are slathered in grease. I found the exposed overhead cam to be very interesting! An overhead cam was way ahead of its time when this was built. Another great walk around! 👍

Hub center steering, the holy grail of motorcycle engineering!

[@RobertBrothersJr-dc7nr]

What a unique tractor. It’s absolutely amazing what they could do 120 years ago without the technology we have today. I can’t imagine the knowledge the designers of this must have had. Another fantastic video Squatch. Thanks

[@grasshopper7760]

Thank you for sharing this ✌️

[@sheldonjr7hp]

That was a very interesting tractor. Amazing amount of parts were recast. Both cylinders were new. Guy I was talking to said it took like 5 attempts before the cylinder came out right. The exhaust manifolds you could see were made with a 3 d printer to be cast. After seeing it in person I’m glad somebody took the time and resources and brought it back to life. Probably one of my Favorites at the Albany show.

[@Wheels_of_Interest.]

Yep that's the one on CTF, an incredible achievement to remanufacture so many complex parts with new technology , when you watch that video of it being rebuilt it makes you wonder how they designed and built these things with 120 year old technology. Thanks for the up close walk around, truly superb 👍

[@michelbrodeur6055]

Thanks for this walkaround and the descriptions concerning the individual components. I agree it's an interesting piece of history especially the steering system and hub assembly. The additional video of it running was the icing on the cake or whip cream on the pie (your choice). Thanks Toby.

[@james.carty.9043]

Beautiful old machine they built them with style in those days thank you for showing us it Toby.

[@geneguenther4325]

Wow! That’s a really neat piece of history right there. Glad they brought it to the show for everyone to see. Thank you for the walk around Toby!

[@johngibson3837]

Beautiful old lump respect to the rebuilder and thanks for your walk around

[@nightstorm9128]

That rim mechanics on the side of the machine is a work of art,,,It reminds me of the inside of a 19th century pocket watch,,,Just 100 times larger,,,

[@maggs131]

God bless those that take up the mantle of preserving these big beautiful mobile mechanical pieces of art. An amazing display that at any point in history there were geniuses pushing the limits of the time. ❤

[@brycewiborg8095]

Incredible. My Dad was 7 y o when that was built. He told me that the first tractor he saw around Madelia was a Moline Universal. Tusen Takk.

[@oldavguywholovesRCA]

That's got to be the coolest damn machine I've seen in a long time!

[@dougkubash8673]

It looks like it is still in service! What a cool tractor!!

[@lordcaptainvonthrust3rd]

That is a fascinating old beast Thanks for the walk around Squatch 👍

[@timothyball3144]

That front wheel is wild!

[@ron827]

You have an incredible eye for unusual details. Tnx for the educational walk around which you are noted for,

[@jamesbutler1862]

That thing is a work of art.

[@tractorhyatt7044]

Very unique tractor! Thank you for the walk around. Keeping history alive!🚜👍

[@seniorelectrician6831]

I did enjoy it! I just got back from Indiana, it was a very good show there too. it was more newer tractors and older ones. it was also a carnival with it and a sanctioned tractor pull.

[@markhelseth253]

Excellent. Love the old equipment walk arounds. Your knowledge and narration make the videos. Thanks.

[@rw3dog]

What a find. Thanks for sharing. That thing is awesome

[@philipr7686]

Your walk arounds are always entertaining, and hold our attention.

[@rickyjessome4359]

Thanks for the video, Toby. That is a very neat tractor. I'd love to see how that front wheel works. It's such a unique setup. Cheers

[@mitchcardosi92]

You missed one of the most interesting, (to me at least) features of this tractor, and that’s the fact that it is an overhead cam engine with hemispherical chambers, which for the time is an extremely advanced design

[@squatch253]

Yeah I sometimes don’t catch everything there is to see, if I know the owner of the machine and get permission to climb up on it and spend some time looking around I can point more things out. But when I have to stay on the ground I can only see so much lol 👍

[@michaelscriffiano9267]

The engineering behind that is amazing.....

[@Framo60]

That's a meticulous and - if I dare say so - perfect restauration. And it is really a good looking machine as a whole as well as in all the details - there is nothing of the typical awkwardness in the design which we see in other machines of this time.

[@fuzzwack1]

I just love the old time tractors,and the sound!

[@tatoo3796]

That's awesome. 1 of 3. I should have went to Albany this weekend.

[@garyschmidt4213]

Great walk around love the old hart parrs if you ever get to Charles city area the Floyd county museum has a lot of hart parr Oliver and white farm heritage even an experimental Oliver tractor

[@hartparr]

I wish you had come tapped me when we cranked it! I have looked to meet you for the last two years at Albany. Great video!

[@slantfish65sd]

Hey! Awesome video! I'm so glad you made this. I love seeing these prairie tractors like this. They are really just incredible that one in particular looks like it has an overhead cam configuration with the valves inclined at the angles that they're inclined at. It almost looks like a pent roof or almost A hemi head Great video!

[@clydeschwartz]

Excellent video that is a really neat looking early tractor. I see lots of experimental or prototype stuff on that tractor I have seen a few of them over the years but never a single front wheel it was possibly a prototype back in the day . Keep up the great videos

[@nathancarlisle2801]

I would love to see how that front "Hub" is put together . A very cool tractor

[@johnnymorrow63]

So cool so many moving parts on old equipment!

[@deannajoseph]

Weathered lettering eh. Fancy, who would ever do that. Tush. Thanks for the walkaround.

[@haydnstevens3108]

Thanks for showing the write up it was an interesting read 👍🏻

[@stevea9604]

Great overview…This was as cutting edge design & engineering at that time…It was the Tesla truck of it’s day 👍🏻🤩☝🏻😎

[@calrob300]

Yeah these old prairie tractors especially the steam ones would blow up from time to time, like Teslas catching fire😅

[@BobY52944]

Repro has such a bad reputation. Someone has re-engineeered and re-created a unique Hart Parr. Great work.

[@Oliver66FarmBoy]

The one in CC at the Floyd county museum has had a cosmetic restoration. Just don’t think the funds are there to bring it back up to snuff.

[@jmailbell]

what a neat tractor, thanks for the video!

[@Eli-lb7em]

As I recall that whole engine is new and re cast. Look up the pre 30 tractor school. They have a couple hour video about recasting it all.

[@squatch253]

Thanks, but the one main thing I never expected to happen when I made the switch to doing KZbin full time, was that I suddenly wouldn’t have any free time to actually WATCH any KZbin lol 😂

[@TugboatMatt]

Very neat machine! That engines design looks quite similar to the old Cummins engines

[@davidkimmel5153]

Thank You for sharing.

[@ericsargent4551]

Great video!!! Thank you for sharing!!!!

[@wagon9082]

Good video

[@bobearl7859]

Did you see that the other day that the Kory Anderson Case 150 road train pulled 51 bottom plow the outer day

[@kenhawkins1033]

It was an incredible show and swap meet. Sadly, the only thing I brought back to Michigan was a serious dose of strep throat. I'll be back next year.

[@squatch253]

I’m still sorry to have missed you there Ken, it seems that these shows just get busier and busier for me every year and I just run steady from place to place and tractor to tractor, with lots of conversations in-between it all. I was there for 5 whole days, yet I only actually remember about 2 of them lol 😂

[@Thomasgarrick113]

Very interesting machine those guys were not dumb I wonder what the holes down the center of front wheel are for it's like there is another piece you can bolt onto it for whatever reason whole thing is very unique in many ways I'm sure you would have to be a REAL man to operate one all day

[@jeffcraft3980]

I guess it's a ball bearing setup like your bicycle steering stem.

[@RHarris42]

Now that is freakin cool!!!!

[@larrydavidson3402]

Most interesting.

[@Pamudder]

Thanks!

[@scotcoz]

Again WAY COOL thank you

[@woodhonky3890]

Ancient hemi!

[@Pamudder]

What a marvel. Like a dinosaur becoming a bird. Disc brake(s) in 1912! LOL. You describe the source of ignition electricity as a dynamo rather than a magneto. Do you know what was used to boost the voltage to the many thousands of volts needed to jump a fixed plug gap?

[@squatch253]

I’m not 100% knowledgeable on these, but that belt runs something that very closely resembles a generator and that then feeds a set of ignition coil-type components that have windings in them similar to the old Fordson tractors and Ford Model T car ignition systems. The voltage increase happens within those coil windings, similar to the Ford systems.

[@Pamudder]

@@squatch253 OK. Like a Model T, from the same era. Thank you!

[@hartparr]

It actually runs on 2 model T style buzz coils. We have a switch in place to start on battery, then switch over after it's running.

[@calrob300]

The front suspension seems to be a very smart bit of engineering! Toby, at 2:52 you said that component looked repro to you. What was it about it that led you to think so? How does one judge that? Thanks.

[@larrybl]

Im 20 minuets from Waco.

[@SublimatedIce]

Does someone mind discussing/explaining the different styles of cooling/radiators in the pervious video, and on this tractor? Some almost looked like boilers with tubes, without the boiler; others like this one, look like their cooled with stack effect? I've tried googling, but without knowing what these different designs are called I haven't found much.

[@dwjr5129]

Any chance you caught any footage of it in the parade?

[@squatch253]

Yes, I included footage of it running at the end of this video, plus a few shots of it driving around in the other episode I uploaded just previous to this one 👍

[@ZaphodBeeblebrox-ry5zs]

👍

[@wsbrand]

cool

[@lukestrasser]

Seems like a lot of work when a guy could just swap in a 350 Chevy or an LS.

[@steveolesen8033]

Sorry that my question is off topic from this video but I was wondering if you have the noise figured out in the H?

[@billh230]

Yah, about a month ago. What had happened was one of the cylinder liners had worked itself loose ( it was a hair too small for the opening), and whenever the piston was on an upstroke, the sleeve would knock against the cylinder head. Apparently, a new sleeve fixed the problem, no further damage.

[@steveolesen8033]

@billh230 if I recall correctly that cylinder was a size E? Did you have to hunt for a special sleeve to fit or was it just a standard replacement?

[@billh230]

@@steveolesen8033 I think it was a standard size replacement. Reaching into my memory (carefully, don't wanna get bit!), Toby mentioned that the last major engine work was a refurbishment, not a rebuild. The original liners were left in place at that time. Also, the letter sizes refer to the size of the bore, not the outside diameters of the mounting surfaces.

[@tmscheum]

👍👍👍Comment👍👍👍

[@aquilaaudax6033]

✋🏼🇦🇺👍🏼

[@andrewevans1658]

Instead of making a video about something you know absolutely nothing about you should have interviewed the men who built it!!!!! I will give you a clue, two of them were in your video!!!!

[@squatch253]

I’m not here to bother people or get in their way, nor do most people want to be put on the spot in front of a camera. With those courtesies in mind, I try to do most of my filming when nobody else is around 👍

[@aserta]

It's a walk around, not a "talk show". You want more info, there's pages of the makers. Squatch tries to give us an overview, you want more, you have to go there. And i say that being European, having almost no time to visit.

[@machinistbytrade]

That front wheel most likely has a large plain bearing being as its externally lubricated like it is

[@mikewilson631]

My thought as well, plus the state of steel technology in 1912 was probably not up to it being a rolling bearing. For example, only in WWI were exhaust valves made from stainless steel (and even then only in aero engines) removing the need for regrinds every 200 miles or so. Not missing a zero in that number...

[@20AR]

It actually has two big flange bushings one from each side, that meet in the middle. The tractor actually has ball bearings from the factory on the first reduction shaft in the transmission.
