Herman the Oliver 1950 tries out mufflers, and a straight pipe.

- I thought I would make a comparison video to show just how loud Herman really is, but the decibel app on my phone wouldn't go that high! I went ahead with filming 2 mufflers and a straight pipe for sound comparison, and then my brother filmed some great action shots of Herman discing.
It's worth noting that since the decibel scale is logarithmic 100db to 103db isn't a 3% increase. Sound pressure intensity doubles every 3 db due to the logarithmic scale. So 103db is TWICE the sound pressure intensity of 100 db, 106 db is 4 times as intense and so on. Anything over 85db will result in long term hearing loss from prolonged exposure.
That is the first they taught us in aircraft maintenance school. Working around jet engines can really damage your hearing. Sometimes we had to wear ear plugs and ear protection.
You will have to speak up, I’m wearing a towel?
This is great. Had no idea. Will do research
Luke Strasser you watch this channel too luke
@@fredorico41 sir do not mock my headdress it's called a turban
I love Herman! I especially like the patina! A new paint job wouldn't do him justice.
Hello Chris,
Thank you for your time and effort to conduct such an experiment. The sound of the 2 stroke GM's was unbelievable. I can still remember the first time I heard such a beautiful sound. It was a Terex scraper running two. My vote is for the straight pipe it really let her speak! Of course good ear protection is a must,
God Bless, Boe
I knew when you said that you would put on a straight pipe , they,d get a ear full. GM engines were always Loud no matter what. My neighbor had oliver with GM engine 4 ft chrome pipe could hear him for couple miles working . Olivers were built so well , that is why they are still going strong, ones taken care of, maintained etc. Our family had a Oliver / White Farm dealership 25 yrs. I still have a older 550 with several factory attachments .Oliver will remain my tractor of choice forever. Enjoy your channel.
Thanks!
That Tractor looks like a mod vehicle for Snowrunner.
Mark V Did you scope out his shirts?
It's always amazed me how a Detroit at 2000 rpm sounds like it's at 10000 rpm, I comprehend the mechanics of it but it's still odd, that would take some getting used to
It fires on each top dead center. instead of every 3rd stroke like 4 stroke.
I still use my 1955, the waukesha was blown, replaced with Perkins from white combine. I still like seeing the other green tractors.
Ole Herman seems to enjoy pulling the disc and packer, He moves right along.
we have the same tractor out at the farm we never wore hearing protection we ran it with straight pipe once before were the glass in the cab quivered I love that scream of GM Detroit
After working at a Detroit 2 stroke rebuilder for many years ( where we always test ran rebuilds ) , they all sound sweet ( what I can hear , that is ) !
Man I love them old Detroit's
wonderful music to my hears
Growing up on our farm in the 1960's, you could easily tell from half a mile away when our neighbor took his 1950 out to the field .
Herman sounds ANGRY with that straight pipe on em but it’s a good kind of angry!
Straight pipe sounds awesome!
The straight pipe sounds awesome
I love the straight pipe but it would be to much for hours on end in the field.
Agreed. I save the straight pipe for parades and shows.
@@ThatOliverGuyChris 🤣🤣🤣
To me the stock muffler sounds best at WOT. Low to mid range, straight pipe all the way. Can't beat that Detroit diesel sound!
That straight pipe sounds sweet like a stock car! 😂 haha. Really Loud!!!!
Neighbor has a 1950 with the Detroit. The motor is loud no matter what you put on it, so he has a 5” chrome straight on it.
Thanks Chris nice work 👍
You're welcome!
Great camera work Jeff!
@@lukestrasser thank you!
It makes Herman look different at a ways off because of the straight pipe sound.
Love the sound of that screamin Jimmy!
Sounded great the staight pipe would make my ears ring 👍👍
The camera mic was really struggling to handle that straight pipe. Lol. Back in the 70s one farm to the south west of us had a 1950 and another farm to the south east had 2 5020’s with Kinze 318 repowers in them. All the neighbors say you always knew which one was working ground by which direction the sound was coming from. Dad said on a calm night that sound would easily carry 5-6 miles. Wish I could have been around back then. Like Blain told me when I went out and looked at that 8700, that was back when everyone got along and there was enough to go around.
I was impressed how well the gopro handled the sound level, the biggest thing is it adjusted the gain so that the quality was still there, but the difference in volume is gone. My would have sounded like it was under water. Lol
I agree with Blane, and in many ways us farmers are our own worst enemies. We are working our butts off, so we get bigger equipment to get the job done quicker. Well, now we have extra time on our hands, we can take on an extra 40, 50, 100, you name it acres. Then we're working 20 hours a day again, time for even bigger equipment. We force ourselves with our competitive nature to be bigger than the next guy down the road when we were making a good living at the size we were. When it comes to our food supply, bigger isn't always better, as the meat packers are showing us now.
Detroit= wide open or nothin!
True that, they don't like to lug down.
I drove a Chamberlain super 90 when I was a teenager, couldn't hear for days afterwards.
You gotta drive them like that, Detroit’s make power up top that’s why it’s go or blow
Straight pipes with the earmufs is the way to go!
Well, that was interesting, Chris! That old heifer sure can bellow! I laughed when you put the Stanley muffler on, it was kind of wiggling around, had that been me, the damned thing would have fell off and I'd have run over it!! LOL!! I noticed that a section of the packer got full of mud, always wondered how you clean those out? High pressure washer?
The wiggling is why I throttled down a couple times. It was working its way off without a clamp due to back pressure.
I picked up the mud along the edge on the first pass. Usually it's not too bad. Loosen up the clamp and pry the wheels apart with a crowbar and knock the chunks out. I have used the power washer in the past, that just moves the dirt from the packer onto me. Lol
Good morning love it
At 8:16 I like how he is wearing crocs
I like herman .will nice tractor an. Awesome video.
Thanks!
Detroit's always sound the best with straight pipes
Straight pipe all day
Keep the straight pipe, that thing sounds mean.
with a lot of diesels they govern them up for tractors
with GM they governed them down
In my opinion, the Stanley and Straight pipe sound the best. The Stanley is somewhat quiet like the original but more Throaty & Deep.
i thought it was insanely loud with muffler....straight pipe proved it could be worse !
Every one of your neighbors heard it in a 5 mile radius! I'm sure it helps with social distancing! In cities it would disburse riots. All good comes from straight piped Detroits.
👍👍👍👍
That last one is hella better!
Run straight pipes on my JD 70 and 730. Allows the country side to know when I am out there baling hay all night. The stacks are a little higher than normal.
The Standley make Herman sounds restricted and having a hard time breathing. The Nelson does the best job of reducing the noise while letting it bearth. Straight pipe is the loudest and breath the best.
Just my two cents i just closed my eyes and listen to be able to tell the difference the best.
The Nelsons seem to be a popular choice for Detroits (at least it seems like that in Facebook tractor groups)
The Stanley definitely had back pressure. The couple times I throttled back it was because the Stanley was working it's way up off the pipe. Idle down some and it would wiggle back down. This was without a muffler clamp.
Like your outdoor camera crew I bet you do too chris
He's pretty handy to have around. Lol
I have an old Tandy Decible Meter. I am very familiar with sound environment restrictions because of Air Conditioning Compressors and Fans. I’m guessing that at idle your sound is close to 200 Decible and under a load at 2/3 power your probably at 600 Decible
You should install a resonator AND muffler from a pick up truck having twice your tractor displacement.
It's would be more comfortable for you.
Keep your exhaust tip the same diameter as your stock one.
Also acoustic panels on the side of the engine would help a lot at reducing noise, you can space them to let air flow.
I prefer the sound of the Waukesha engine over this. This Detroit sounds pretty good though
What do you use for mounting your camera? Everything I’ve used is way to shaky and vibrates way too much
I've got a magnetic mount. I put thin packing tape over the magnet to keep it from scratching paint, works great. The action shots that my brother took from his 4 wheeler were all hand held. He did a really good job. The Gopro7 also has awesome image stabilization, so that helps.
Thats a hell of a good machine.straight pipe looks better 2nd muffler sounds better
I never seen a disk like that with the wings offset from the front gang.....I would be curious what the true decibel level was on each wide open.
I've got a real decibel meter coming, so I will redo this test in the near future.
Put the round muff back on it, sounds a lot better gives it that strong sound like its breathing better, sounds good like a Detroit should.
Cool video, I wonder how loud it actually is. My guess is over 100 with the muffler and like 120-150 with the straight pipe.
The app I had said 140 is physical pain.
Great video Chris. I’ve heard that a Detroit motor looses power with no exhaust restrictions. Something to do with the 2 stroke process
That isn't true, they loose power with excessive exhaust restriction, there is no detriment to running one without a muffler at all. The Detroit manual gives specifics for maximum exhaust back pressure.
The Detroit moves a lot of air and needs to get it out for cylinder scavenging to be effective. I think I see a dyno test coming. I've got a decibel meter coming, I hope 130 db covers it. 140 is physical pain level.
@@ThatOliverGuyChris Absolutely correct about the scavenging. They pump about 3-4 times the air through the engine versus what is actually used for combustion. The air is cooling as well as scavenging, considering only the top 1/3 of a 53 series liner is actually water cooled! Later 71 series had water below the intake ports, but a 53 series is only air and oil cooled from just above the ports to the bottom of the liner.
@@lukestrasser, I'm sure you guys are correct with Detroit but with small, gas 2-strokes, pipes make a huge HP gain.
@@augustreil the detroits have a blower that runs 2-3 psi positive pressure. Your 2-stroke dirt bike engines have no blower, so pipe design greatly influences cylinder scavenging.
Man, was it recorded by washing machine?
A Kenmore on the spin cycle
Sounds good
So in Ohio they tile fields 1" per 100ft I live in Pennsylvania so don't know if it does the job 🤔
That was cool filming using the atv.
Thanks!
Was that Detroit the original engine?
Yes. Oliver typically outsourced engies on their larger models.
@@ThatOliverGuyChris interesting. Whatever happened to the Oliver tractor company? Whatever it was, it must have happened a very long time ago because they seem to be pretty rare, i don't think ive ever seen one in person. Same with Yanmar tractors. Anyways, is that a 53 series detroit? Or maybe a 92? I don't think the 71 series was out yet when that was made. Im guessing maybe a 4-53?
Reminds me of a terex scraper
Is that a 4-71?
It's a 4-53
@@ThatOliverGuyChris It sounds bigger. I'm in the process of putting a 4-53 in my pickup. I love the sound of Herman. People must hear that tractor miles away.
A pickup with a 4-53 will be awesome! What are you going to use for a transmission?
@@ThatOliverGuyChris Hey Chris, it's going in a 1984 Chevy K30 CUCV. It's got a 6 inch lift so I won't have any oil pan clearance problems. I'm going with an NV4500 so I can just bolt my transfer case to it. I'm trying to keep it simple.
Chevy guy here, so I know it will be cool. I've been thinking a 4-53 with Oliver's 3 speed powershift then coupled to a 4 or 5 speed manual transmission would be a cool combo, but would take some fabbing to make work.
The atv vid is as good or better than a drone
Thanks, I'll let my brother know.
Screaming Detroit poower😊
Herman is quite,! A ride lol
Terribly loud . u want earplugs and also headphone type protection at same time for this thing. Id like to see how this thing could match up to rodan and give king kong. a day off.
There call screaming Detroit's for a reason
Scream'n demon's
Sorry Chris, should be row instead of roll.
Vote straight pipe
New to the channel. I know that Detroit Diesel + Straight pipe = LOUD! And next time, try a chrome straight pipe!
We run both of ours with straight piped and no hearing protection
*I wonder how a two cycle detroit can run straight pipe and a stupid 2cycle dirt bike can't?*
The Detroit has a blower to force fresh air in and exhaust out. The less back pressure the better.
@@ThatOliverGuyChris anyway I hate the look of a two stroke bike pipe
Sorry but this sounds almost like a grass cutter. 😂😅
Lol, I guess you had to be there. A neighbor 2 miles down the road could hear this.
@@ThatOliverGuyChris hahah alright, but honestly the tractor looks powerful. 😉
Implements: it's been a long day
Oliver: nice of you to join me, how long have you been back there? I had no idea!
The straight pipe sounded like the old Euclid scrapers my grandpa used to operate...
i love them things, the terrix ones are super nice too
I think the older ones had 4/71 later they got into the 6s and even 12s if I'm not mistaken. The weirdest/coolist thing Euclid ever made was the twin engine dozer. It had 2 6/71s and pivoted in the center for better traction. Kinda s cool idea.
We use Euclid mill dump trucks at the steel mill I work at, I love how they sound.....supercharged v8’s
Straight pipes and hearing protection is the way to go
He's a beauty. Detroit's are the funniest noise makers out there.
Is it a 3 or 4x53?
4-53
We have a couple at work in old Taylor container lifts. No one is sure of the year they were old 20 yrs ago when we got them.
WOW that sounded good straight piped !!!
Chris - Not sure if your interested in a collaboration but another YT channel, Cole the Cornstar, is planning to do a rehab of their Oliver 1950. Apparently the problem is that diesel is getting into the oil. I'm guessing it's the injectors that are bad but who knows for sure. It's Cole's brother, sorry can't remember his name, that will be wrenching on tractor.
I wouldn't be against that but they're out in Iowa and I'm in Michigan. Last time I saw them mention the 1950, they were talking about selling it, must be they changed their minds. Cooper is the brother's name if I remember correctly.
Without doubt Herman is a fantastic piece of kit and I wish he was mine. However, that noise is enough to make your ears bleed, I had to fast forward to the end, sorry. Herman gets a 👍 though.
Don’t seem to matter you never seem to mask the sound of a Detroit lol. I always had ear plugs when I drove our 1950 growing up!
herman seamed to do better with the straight pipe when you would drop the disk in the ground or up shift the over under it seamed like there was less bog down till it got to its happy spot on rpm's
Love that tractor and the straight pipe sounds cool but if I was running it for more than a few minutes....I’d probably use muffler #2....it has a nice sound
Oh my goodness that thing sounds awesome! Someday I’m gonna build a street rod with a 2 stroke Detroit in it. I love that sound!
I've seen some pickups with the same engine they are sweet.
3-53, 4-53 will fit nicely into an engine bay previously home to a smallblock V8. Just sayin'
@@TestECull I got a three-quarter ton 2 wheel drive Dodge that's got at 4:53 and it with a five-speed it screams
Nice video awesome straight pipe
Straight pipe sound cool would definitely wake neighborhood up! Neighbor has a 4030 John Deere non turbo 329 6 cylinder that had a straight pipe. Sounded like a monster truck!
Chris, check out Cole the corn stars channel. They have an Oliver with a Detroit they drug outa a shed and wanna sell.
Thought he said they were going to fix it in his last episode
@@Derek_00Mustang83, Yeah, I think they're gonna keep it now. It looks like the same exact tractor ?
Yep, it's a 1950, same model as Herman. I'm glad to hear they are keeping it, it looks like it is in good shape.
You know, I think I may have heard Herman out here in Central Ohio when you put on that straight pipe. Years ago I had A GMC dump truck with a 671 Detroit, good old engine.
they really scream with a straight pipe. i would like to see a 212 cubic inch 4 stroke diesel pull that load
That strait pipe sounded amazing I’m not really a strait pipe kind of person but that Detroit diesel sound amazing especially when at idle. But I would put a muffler on while working but if I took it to a show put the straight pipe on
I have a suggestion, any configuration of exhaust I guarantee you will wear hearing protection, so why not hook it up to the dyno and see which if any of the exhausts makes the most power. Sound is fine but I’d shoot toward a power gain.
That's a good idea. I've ordered a decibel meter, so I can check that at the same time. Thanks!
Man this is straight up tractor porn. Dang I love it.
ah, the sweet sound of a straight piped detroit at work.
Old herman barks with that straight pipe ! Good video chris...
I would take that muffler off it won't go back on again straight exhaust sounds alot better and it let's the engine breath more now it sounds like a tractor should U must didn't go 2 any sawmills when U were growing up they ran straight exhaust U could every line that was sawed when the wind was just right U could hear it for miles OMG 12 8 2O22
lol
did the neighbors file a noise complaint yet?
Yup, it's a Detroit!
Maybe could have noticed a difference with the sound meter if you put it farther away.. wouldn't be accurate, but you would know which one was loudest..
That was some SMOOTH four wheeler video!!!
Good idea, Ed. I need to put you on speed dial.
@@ThatOliverGuyChris LOL.. you knew it, you just didn't think about it 😎😁
That straight pipe made all the birds leave my bird feeder.
I like the straight pipe ..
but I can shut the video off , it would make for a long day
this sounds so sweet to me.. but I grew up running 6-71 and 8-71 Detroit ..
Haha this is gonna be a popular video! He sounds pretty mean with that straight pipe. I just ran the rack on a 4-53 last week I was thinking about your Oliver. Have a good week Chris great video
Oh gosh! U rev'ed that straight pipe and it made me so glad I'm not ur neighbor. Hahaha! I bet that was beating through the walls of the house a mile away.
I think your neighbors 2 county's over can hear you. 🤣🤣🤣
Seriously though, Herman sounds awesome!
