Tractor pulling has got to be the most bat-shit insane racing sport. "Hmm... I have 5 3000hp blown V8's. I know, lets tape them together and strap some wheels on them!" Same goes with the jet powered ones. I fucking love this sport.
And all done by some farmer with money. Not mocking them...far from it. They do AMAZING crap with ingenuity and hard work. It's incredible engineering. Imagine the stress on that driveline!
I've been to shows in the Omni in Atlanta many moons ago and health issues were inevitable regardless of where you sat. Down low and you lose hearing. Up high and your eyes and lungs get fried from the exhaust. But back then the cheap seats meant you didn't have to buy overpriced beer because the high was free 😄
Those pry bar things are starting bars,the other engines are used to start any engines that have stop running,they pull back on the bar to cause the clutch to engage on the non running engine causing it to turn over and start.
Thanks for the upload of this vid. This Motor stuff, huge and unbelievably powerful when things go right was the first 'American' thing I watch on Sky TV.
I remember when tractor pulls where,when farmers brought there tractors to the fair to compete aainst each other,then money gets involved and the fun turns into this the grand prize was worth winning these guys blow up one motor and it costs alot more then they would have won
Direct drive, similar to inboard boat engines. There is a clutch assembly in there somewhere, and a giant case where all the shafts mate up with a monstrous ring and pinion style differential.
So much engineering goes into making 5 massive engines work together to make a ton of power. It's a shame that there isn't a more practical use for it that this.
@@jimstepan3038 Yes, there needs to be a fair balance. Everyone can think of it this way.. If your car has 1000HP and you geared it to have a super long gear that had a tiny bit of torque, you will start moving, but once the air and friction starts effecting your car, your maximum velocity will be almost nothing.
Jon I would, actually, like to do this. They used to come to our town, but that was years ago. I guess they did not have the attendance to sustain it. We still get the monster trucks, but no tractor pulls.
thastinger345 yes. Thank you it seems to happen more and more. If I don’t see action within 30 sec. I’ll check comments. Haaaa. I’ve got attention span of a toddler I guess. No patience lol
dunno its not a matter of pulling its overcoming the drag from that sled.. If you watch an oversize load going down the highway you'll notice the little truck has no problem pulling 40 ton steel rolls.. because its not pulling it... its just sitting on top of the 12 tons multi axle trailer... ooooohhh more wheels, less friction, more easy to pull.. ;-) the science behind it is the contest not the weight they're pulling
Can someone explain to me why it is so easy for the tractor to pull at first but seems to become more encumbered the further it goes? Does the trailer dig more into the ground the further it travels?
the weight thats on the trailer slides - so the further they pull, the closer the weight gets to the back of the tractor. the closer the weight is, the harder it is to pull.
It doesn't "dig" perse, but drag. The friction goes up as the weight presses the sled into the ground harder as it moves forward, making it harder to drag along.
Just being a internet fucktard is all. But if I was a betting man I would wager that's Podesta and Clinton under those robes, most likely transporting a box of children to some dank basement for consumption.
@@motominded5275 I guarantee that a good size steam traction engine will pull a heck of a lot more weight along further before it starts to lose grip, abeit will be a lot slower in the process. Either way one would be able to keep pulling that sled all day long.
That's the limit of the tractor weight. In the US, this would be similar to the 9600# class. Just before pulling, they go across a scale, and if they can add weight, they'll add it to the front end. For those comments on the small tires: They are that small so they can turn quickly when they come onto the track. Also, if there is any touchdown going down the track, the tractor will turn more. However, the drivers drive more with the pedals than steering wheel. Each side has a brake; if they are drifting to the right, they brake on the left to bring it around. I know there are lots of people that don't like this sport, and that's ok. The beauty in this sport is getting all the power you can out of a certain weight restriction. Like another poster said, there aren't cooling systems on these (except for some of the Super Stock Diesels), and that's why they were running around in this video. Also, there is a time limit from the time they get on the track until they can begin their pull. For newbies: Look closely at the small box on top of the sled. As it goes down the track, it moves forward, off the wheels of the sled, and onto the flat dragging part of the sled.That's what slows them down. Tractor pulling has very little to do with speed; the contest is in the distance pulled.
on high compression engines like these blown alcohols, those 8 pistons are generating a lot of crankcase pressure via blow-by ( pressure passing the piston rings into the crankcase after ignition). you have to bleed it off or the pressure will build and either it will try to go back the way it came in, or blow oil out of you valve covers. to relieve the pressure, either a hole was placed in the crankcase itself or two tubes coming down from the valve covers merge to one and dump underneath.
never seen so many idiots run around a tractor just to be seen in my life. lol I'm a puller and know what needs to be done and nOT done. this was just comical...and what exactly was the woman doing besides running funny? oh but she had a suit on to look important and to make sure people saw hwr....of they saw her alright....again, comical😂
The vents you see is just crank case ventilation. All cars have them but normally use a PCV (positive crankcase ventilation) system that recycles it back through the engine for emissions. There is no cooling because they run on alcohol which flows so much fuel it actually runs cool. After a pass the blowers will actually be frosted over.
