1955 International TD6 diesel crawler

[@davidsitzenstock2844]

That is really straightetal wise. I'm now 82, our family had one of these with the bosh(sp) pump. Thanks

[@Steverinomeister]

Thanks for posting this very interesting and informative video. My hat is off to the ingenious designers of these old diesel tractors.

[@mainebigfoothunter7088]

It's geat to see the old technology. My father had a Farmall 400 Diesel that started on gasoline and then swapped to diesel after the motor warmed up a bit. May have been the same motor as this TD. As a kid, I liked the smoke rings the old tractor made when Dad switched over to diesel

[@brandonbarnett9703]

That is an absolute beautiful crawler i always wondered how the gas to diesel switch over worked and you explained it perfectly appreciate the ih book with the pictures of the cylinder head internals Thank You

[@lorrainedimmock4096]

Nice looking machine, remember the BTD6, on the building sites in the 60s/70s, these machines were the Drott shovels, with Drott supplying the hydraulic arms and bucket systems of the machine and were a major step forward from the old rope operated Chaseside loaders then.. They were painted red at first, later yellow.. The British versions were built at Rubery Owen , Warrington, who also built the famous Barber Greene pavers, both under licence from the American owners and became a standard site on the post war construction projects in England.... You have make a very nice job of your machine...well done..

[@tomheringer2047]

Wow! This brought back some great memories. My father taught me how to start and operate a TD-14 when I was 4 or 5 years old. Our TD-6 was used exclusively for orchard maintenance. When I turned 14, I found myself on the seat of a TD-14 working 12 hour days during my summer break. It is amazing how dependable these tractors were. With just routine fueling and servicing, they would run forever.

[@jameswilson197]

I grew up running one of these with a dozer blade. Really a great little tractor!

[@fertilturtle]

Really like your crawler. Beautiful machine and sound. Thanks for not playing some ridiculous music.

[@richardjanssen3183]

I like the way it warms everything up at a low rpm

[@MrLostonej]

I got to run one of those with a blade when I was a late teenager.it was one of the coolest ways back then starting out in gas then changing it over to diesel..there was a lot of tricks to starting it and shutting it off. one of the best jobs that I had ever had when I look back.

[@dadyyosccase6209]

Excellent video and tractor. Thanks for sharing

[@josephvalentjr7677]

Thank you Sir Beautiful restoration 👍

[@paulschreiber1364]

Nice presentation. It brings back fond memories. I've always loved the sound of the IH diesels. My father had an MD with the same engine. I learned to drive it at age 8. Thanks.

[@matthewbonaccorso617]

Thank you very much for taking the time to share your TD6 with the ret of us. It really brought back some fond memories. Our tractor was a 1951 TD6 orchard model. It was very slick the way the factory modified all the controls to move them further back for use with a tail seat hanging off the rear end to provide orchard clearance. The exhaust was raw and just erupted right in front of you at hood level...I am sure that it affected the hearing I have today! ;-) Thanks again!--Matt

[@trschoeb]

What a nostalgia blast. I remember the starting ritual well. When I was growing up my family had a farming and cattle feeding operation. My favorite tractor was a TD9 with a dozer blade. I don't know the year it was built. It was worked a good deal and kept outside, so it was a lot rougher than yours. It eventually developed a crack in the final drive case and was sold rather than repaired, even though a salvaged replacement was available. It was replaced with a front loader Cat, which just didn't have the "personality" of the old International with its old-school steering clutches and brakes, hand clutch, and chugging 1500 rpm diesel.

[@lorrainedimmock4096]

I know a Bucyrus fitted one buried in the brambles in Andover, Hampshire, village called Picket Piece, Derek Madder, steam centre...!

[@mingthemerciless6855]

Great looking and sound. Keep it looking and working good.

[@BRI33NOR]

When I was a kid in UK we had a similar tractor, but it was a straight diesel. I think it had a switch you held to operate manifold heaters for maybe half a minute then operated the starter. If memory serves me correctly it was a BTD 6. Good machine, it wood be about 1955/56. Looked just the same.

[@honda4004]

Hi that is what the farmer has stood in brambles near Doncaster U.K. Btd6

[@BRI33NOR]

@@honda4004 By a very slight coincidence may be the same one ! . Farm was situated Lincolnshire / York's border !. Was sold up at auction about 1970 ish. By the way rode one of the first 400/ 4 s in the UK, it refused to run on all four straight out of the box. Eventually found the remains of some great Japanese spider or beetle in the float chamber !. Lovely bikes.

[@bnghjtyu767]

I had one when I was a kid and I also had a super MTA a diesel had the same engine I used to call it mechanics nightmare but I like it.

[@GreenbrokePete]

Wow ! Flawless crawler , you keep it beautiful..

[@marktufts7756]

these are very easy to operate as i put 1,500 hours on the one my dad had

[@bogiewheelman71]

Very nice TD-6 . Own a WD-6 myself .

[@jimsonbrown9768]

You have a great looking tractor there, sir.

[@coreysteen6525]

Dear sir I like your crawler. I have a WD 9 they are very interesting machines but the way you want to shut it off is to never transfer back to the gas side and just let it idle on low on the diesel a old mechanic told me it's hot when you put it back to gas it can warp the starting valves and possibly crack the head

[@ericelton9546]

Very nice crawler.

[@MarylandConstructionDiecast]

That crawler looks great!

[@coldspring624]

love that machine of yours

[@rogersrabbithole8417]

That's a beautiful machine you have. I've been looking for a TD-9 or it's equivalent 150 k-3 loader with the 4-n-1. bucket/blade. Problem being they're not in good shape at all not much more than scrap. if ya can find one ??? Thanks for sharing your TD-6 !!!!!

[@marktufts7756]

i have over 1.000 hours operating the one my late dad used to have

[@rightlurker4674]

Beautiful machine. Weren't the steering clutch levers awfully difficult to use, being so far forward and nearly horizontal?

[@mariebennett5739]

Very nice machine I don't want to be critical but those steering clutch levers are well out of adjustment having operated BTD6s and TD9s those steering clutch levers are easy to adjust up on me a matter of shorting the adjustment rods under the seat and adjusting the lever stops up dosent take much makes them much easier to operate often had to do it on the TD9

[@1000guy1]

Thumps up if Terrence the tractor brought you here

[@SiliconSet]

Great video! Many thanks.

[@lorrainedimmock4096]

I believe these machines were also built in Doncaster, England and at Jack oldings plant in Bury at Edmunds, Suffork, correct me if I am wrong.....?

[@mikeschoeffter7420]

Nice lookin tractor !

[@SiliconSet]

My thoughts ... The change from diesel to gas failed because the float chamber hadn't had time to refill. The needle and seat were closed (by the changeover lever during diesel opration). The instant restart was successful. I'd favour shutting down directly from diesel after a cool down idling interval. Because: Running on gas holds the diesel inlet valves open so running on gas won't allow them to cool. Running on diesel shields the gas inlet valves from combustion and intake airflow cools them. 1. Engine temperature rises after shutdown anyway because the coolant stops flowing. 2, Not restarting on gas will extend the battery life. 3. The gas inlet valves will stay cooler because they will see less exposure to combustion. 4. The diesel inlet valves will be cooler because they will spend more time fully seated. In any case the position of the gas inlet valves will be determined by the cam lobes. Some will be fully closed and others open.

[@richardmaurer9002]

The starting valves, or “gas inlet valves “ as you call them , are all open at the same time; they have nothing to do with the camshaft. Their purpose is to lower the compression ratio for starting on gasoline. Further, it is better to shut down on gasoline, as this clears the spark plugs and combustion chamber of diesel residue , which could hinder the next cold start in adverse conditions, i.e. extreme cold or dampness. After the shutdown on gasoline is completed, the engine is switched back to diesel to allow the starting valves to cool on their seats.

[@Mackeson3]

The British version (BTD6) didn't have that starting on gasoline malarky, it started directly on diesel using glowplugs to preheat the combustion chambers before you engaged the starter. Only one thing you needed bloody good batteries to crank the thing over.

[@glenirwin1110]

It was not malarkey if it was -20F outside. Yes the UK version had glow plugs but England is not Minnesota.

[@Mackeson3]

@@glenirwin1110 I fully understand that. Our B.450 wheeled tractor had the glowplugs, not the easiest tractor to start unless the plugs and the batteries were in good shape, but once it started that long stroke engine would outpull anything in its class. We traded it in for a 674 which was a very good starter but that shorter stroke engine meant power wise it was dead flat compared to The B.450.

What's the mason jar on the air filter for?

[@josephjarrell8342]

KRB52 Cyclones

[@josephjarrell8342]

Air cleaner it spins the air and the more heavy particles fall into the jar before going into the oil bath air cleaner

[@MrMusic1950]

I recommend not leaving the main clutch lever forward when not driving, main clutch lasts 100 times longer if "engaged" as much as possible.

[@jimsonbrown9768]

MrMusic1950 : won't the clutch disk stick to the pressure plate and flywheel? Happens to my little Oliver if I let it sit for a month. And it's damn hard to get it unstuck!

[@MrMusic1950]

Jimson brown certainly not jimson, I operated these for many years and never saw that happen, some would sit unused for months while we pulled a new contract, but never a stuck clutch.

[@wilmamcdermott3065]

Dry clutch should. Be egaged

[@Jack-ne8vm]

Might tie the steering clutches back for storage.

[@johnlewis7736]

Nice!

[@MrMusic1950]

superb &thanks.

[@coldspring624]

Im in love

[@wilmamcdermott3065]

I had a TD14A

[@garethrowlands2862]

The worst thing one can do with a Diesel is to switch it back to gasoline to "cool down". If you know the heritage, a WD-40/TD-40 doesnt even give you the option. The reason for that is, they knew even in 1934 that gasoline burns hotter than diesel. Therefore you are creating a hotspot in the cylinder head by "cooling down" on gasoline

[@glenirwin1110]

I've been told by old timers that almost nobody "cooled down" with gasoline. The idled on diesel until the temp came down and then shut it off. They would really only do the gasoline cool down if it was wicked cold to leave it on gas for the next morning start.

[@richardmaurer9002]

Then why would it say to do this in the operation manual? Was IH too stupid to know how to operate an engine that IH built?

[@johnsavoy4784]

had a TD 24 was a pain to start on gasoline

[@circlecchobbyfarm]

Hard to get parts for?

Shut it off on diesle

[@buguy3349]

Great video ! It brought back memories of me driving a TD-6 when I was nine years old. It was usually pulling a 7 ft drag disc that had a hydraulic ram to open and close using a BG hydraulic pump mounted on the TD-5. I ate a lot of dust while driving that tractor.

[@honda4004]

Hi we have one here in Great Britain been stood in brambles for 35 years if you wish to receive a photo then can email it a old farmer friend is now selling up

[@michaelmckenzie5232]

Not a good gas tractor,not a good diesel tractor.Too many compromises as far as motor design.They sold a ton of these due to the price differential between IHC and Caterpillar.Will not perform near the heavy work a Cat will.That being said, they filled a niche and were still better than any thing foreign made.Nice resto

[@glenirwin1110]

They sold well in Canada and in the cold regions of the U.S. It was something that farmers and smaller contractors could afford and get started in the winter. Sure the Cat diesel engine was better but in the winter it needed the pony motor to get started. Back before better batteries all the manufacturers made compromises.

[@michaelmckenzie5232]

Glen Irwin back in the day , all cat motors needed a pony to start, period.It was how it was done.No electric starters then

[@glenirwin1110]

@@michaelmckenzie5232 Okay. I thought electric start was an option so you would have a unit with the pony and starter if you wanted. Also couldn't the IH engines be crank started on the gasoline?

[@jerrysteele6427]

Do any of you old hands know how much hydrolic oil and the weight of the oil that goes into an international 1965 500 D I have searched the internet with my limited computer knowledge and have found no one that can or willing to do a little research...
