Detroit Diesel. The worlds most efficient engine at converting diesel fuel into noise!

Those old 2 stroke Detroit diesels are interesting engines. I had one in a Dynahoe 190-4 backhoe. That thing could sit for 8-9 months and it would fire right up every time. Probably one of the few engines that there is no real need for a redline because you reach point of not being able to stand the noise long before you get to redline. If I remember correctly the 4-53N I had in that backhoe was rated at 2700rpm and I think I got it to 2500rpm once and almost ripped a hole in space time, thank goodness Captain Marvel was there.

What a beast! That tractor toys with that plow. It does some slipping but never lacks for power.

I had a picture of a 5020 with a Detroit engine hanging in my living room years ago.
My wife forced me to take the picture out to the shop beacuse it leaked oil on the couch. 🤣

Gotta love the sound of a 2 stroke diesel. Use to rebuild boat engines that used twin turbo feeding the supercharged 871. The boat manufacture upped the injector size to meet speed requirements and it burned sleeves and heads regularly. Reduced injector size and no more issues

What a friggin footprint with those rears!!

[wow]

You always love and know the sound of a purring Detroit deisel

I love this tractor. It sounds like my boat and the plow leaves a great dirt wake.

So nice to see an on land plow hitch being driven correctly. Skill. 👍

Well done.

That's a sharp looking tractor. Lots of time, money and labor went into it and boy did it turn out awsome looking thanks BTP 👍🚜

You can cover some ground with that beast right quick!

I ran that engine in a gmc road tractor 40 years ago an still have the God dam ringing in my ears , you had to have the engine wide open all the time to make power . You could hear my truck running across to counties.

I love Detroits. I repowered a Steiger Bearcat 11 which originally had a Cat 3208 (210 HP) I replaced it with a Detroit 6V-92TA with 370 HP. With no other modifications I have run 4000 trouble free hours. Lots of fun and it’s actually a couple decibels quieter than the Cat.

Have lots of go fast cars, class 8 trucks, and tractors. My question/concern would be at what point do you overpower the rest of the driveline and associated systems and start breaking things?? Cool factor is high. But how do you make it live??

My hearing loss from an early age was from the 5020 series tractors, then 10 years later I got a 8v71 in a truck, I can’t imagine a tractor with that engine, it would be deafening and the fuel efficiency wasn’t great either.

Being a retired Army Maintenance Soldier, I know that Detroit Diesels were the primary engines in track vehicles back in the day. The 6V53T was in M113 Series -- mostly personnel carriers. The 8V71T was in Howitzers primarily but also M551 Sheridans, Ammunition Carriers, and the light tracked recovery vehicle. Soldiers would run the 6V53T at idle to stay warm or for mission reasons causing them to overheat which would ruin the engine -- We replaced tons of them in my 7 years in Germany.

That thing is a powerhouse! Great to see some big tyres on it👍😁
