Question/Opinion - not only red/green limited RPM Farm Stock Pullers February 25, 2010 09:38AM
I have been following the "another red / green" discussion as well as the one about the Ford 4 Bangers (be glad you don't have them Fiat 4-bangers - saw one running a H3B at 2700 lately) down below.
We (German Tractor Pulling Association along with a bunch of young pullers mainly running brush pulls) have just started a so called "Farm Pulling Series" for rpm limited tractors three years ago.

We have built the following rules:
Up to 7700 lbs:
427 cui / 2700 rpm / 68mm = 2.667 (HX50) Air Restrictor
OR
367 cui / 3200 rpm / 68mm = 2.667 (HX 50) Air Restrictor

Up to 9900 lbs
550 cui / 2700 rpm - and the same restrictor
OR
510 cui / 3200 rpm - same restrictor

No water injection, but can run intercoolers (which seems to keep temperatures under control).

Anything over 2700 rpm has to run full safety equipment
Under 2700 can keep their cast iron flywheel, need factory roll bar or roll bar with independent engineer's approval, kill switch, side shields, turbo shielding, seat belt, dead man throttle, ...

The Pro Stock class in Germany was (and in a way still is) in p..s poor shape, but pays rather well (transportation costs (250 $ + 1$ per mile) + prize money for top 5 - 400 $ for first and 130 $ for 5th), while the farm stock guys run for prize money only (220 $ for first, 80 $ for 3rd) so these classes are bleeding their top guys into the Pro Stocks yearly (so far). Anybody who wants to spend money is basically gone in a heartbeat and pulls for money, once they have figured out you can better be midfield Pro Stock than top "Farm Stock" with more or less the same tractor and no restrictor.

They can't pull for points, only for the "fame of the day" and can qualify for the finals by winning a class. So following the circuit doesn't really make much sense. Some do, others just pull with us once in a while and for the rest stay at their brush pulls.

The one winning the finals is declared "german champion" and along with the runner up at the finals can go pull in the "Euro Challenge", where the top of each country pull 2 to 4 events a year. No prize money there, just covering of transportation cost by the promoter (which can be quite some money when the guys have to get on ferrys).

I know, quite the socialistic system - but they can always step up a class if they want and run for prize money.

We reckon the Air Restrictor allows them to produce + - 550 hp

Out of the experiences in the last two years:
It seems that with Intercooler, 14mm pump and about 400 cui at 2700 rpm you have enough power in your tractor to win in either class.

We are aware of the fact, we could get a battle for the last 50 hp, but think this won't happen, as spending money in this class is rather useless (better spend it, where there is a serious return).

As soon as things will start to get "bitchy" (when enough of them have gone Pro Stock) we'll give them a class in between without the air restrictor.

Now to my question:
Why are air restrictors (box turbo would be the same idea) not used in US (Hot) Farm Pulling. Are we missing something and have opened a can of worms?

I have a bit of video footage:

this was a brush pull late in the year. The guys under 367 "tested" to run 3100 rpm ...
That black Case/IH 1455 is only 402 cui with a 14mm A-Pump, the 1155 MF runs a Simms, the "Red Baron" has a 466 IH with 14mm P (was it's first time out - driver needs to learn).



the finals
a qualification round after the rain

another one - just outtakes of the various classes (we also run heavier stuff)

In central ontario canada they run a modified farm class 3100rpm no water and a turbo limit size check out www.cotpa.org

Re: Question/Opinion - not red /green limited RPM Farm Stock Pullers February 25, 2010 11:43AM
Any specific reason you've limited the pumps?
We figured a 13mm P can be bought off the junkyard for a couple hundred bucks... diesel tuning shops sell them for like 2000 bucks.
14mm A's are twice the money, anything rotary getting even close more like 3 times that much.
We've tried to stop a waste of money spent on cheating there....

Re: Question/Opinion - not red /green limited RPM Farm Stock Pullers February 25, 2010 01:45PM
the rule says they must stay stock appearing IH has to run rotary pumps deeres can run in line pumps

Re: Question/Opinion - not red /green limited RPM Farm Stock Pullers February 25, 2010 10:51PM
While I do not have a tractor in this class, I have watched this class compete many times and yes from what I have overheard this pump rule has added extra cost into many of the tractors. the small stanadyne rotaries have to work very hard to keep up to the bosch inlines and model 100 ih pump. I believe they do limit turbo somewhat over a certain c.i. Further south in SWOTPA they allow p pumps but limit turbo inlet size , so far civil war has yet to break out in their organization unless of course the subject of a certain blue one is raised? Am sure others can enlighten us on this subject further? IMHO.

Re: Question/Opinion - not red /green limited RPM Farm Stock Pullers February 26, 2010 09:09AM
Yes Jim, there is something shady going on over in the south west!!!!!!


Any new news on Centrals 8500 mod farm class???

Jim seems those blue ones are always shady lol You and dirksons

Re: Question/Opinion - not red /green limited RPM Farm Stock Pullers February 26, 2010 10:57AM
Sascha,

The rules look like a great combination that lets just about any brand or size engine be competitive.

Is the 2.667 Air Restrictor on the inlet, outlet, or both? Is it measured at the housing, a restrictor plate, a restrictor tube?

For some reason the terms “restrictor plate” or “restrictor tube” does not tend to be very popular over here in the US. Personally I think they are an excellent idea, and they still allow the pullers to get creative with turbos, but are a cheap way to limit the air.

Re: Question/Opinion - not red /green limited RPM Farm Stock Pullers February 26, 2010 01:08PM
We basically let them suck all air through a 68mm inner diameter tube with a length of 20mm or have a turbo with no more than 68mm inlet (since the 68mm tube will allow a little more airflow than a 68mm turbo inlet).
So, as long as they run an HX 50, they don't need the restrictor, HX 60 they need the restrictor.

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers February 26, 2010 12:49PM
what gears are they running over there, we ran close to direct with 13mm model 100 and stock 3lm at 11,500 lbs, videos look pretty slow at those weights.

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers February 26, 2010 01:46PM
That is hard to tell. Except for the MF, the black Case/Ih, that Red Baron and that 504 Case nobody ran a turbo that was "on the limit". The only ones having serious pumps in, were the black Case/Ih and the Red Baron.

This all is still very new to them and basically most of who compete in those clases have been on the "scare the local farmers" agenda with rotary pumps and "stock cheater" turbos and the rpms wide open, so are not really purpose built machines.
I am just glad we got them together on common ground and now all heading the same direction and the rpms at the brush pulls have come down from 4000 to 3200 (except for some smart asses who still don't get it) and in a lot of cases 3000 to 2700 are enforced by the teams themselves.
It seems with fire ringing the heads, 13mm pump, a 1000$ Turbo and an industrial air to air intercooler you are all set to be competetive for now. The fact it will not go much beyond this and should stay kinda affordable for quite a while got their interest. It will take 2 to 3 more years until we have enough tractors for a "close competition" at the top though. I am basically dealing with young guys here, who don't want to invest much more than 1000 to 2000 $ a year into the tractors.
The other problem is to find tractors here, that are big enough to be turned into a pulling tractor. Those IHs with the 358 engine were considered "huge" for their time (70s) and the only other tractors that were close in performance (8006 to 13006 Deutz, the 8 cyl inline Schlüters and 611 to 618 Fendts) are already getting collector prices paid for already - or like the Fendts, are still popular at the Farms.
Also, the eastern Europeans are sucking the used market empty. Anything that still runs is going to Poland, Romania, Bulgaria, ... to replace a fleet of Belarus tractors.

A late 1970s IHC 1455 with the DT402 engine (358 block with stroker crank) in running condition and around 15,000h is still 15,000 US $ - if it looks half way decent and around 10,000h, they go for 25,000 $ and up.
130 06 Deutz - there was only about 200 of them ever registered in this country.
8000 - 9600 Ford - never sold them here. 8700 and up were - but not many.
AC, White, Case MM, Oliver,.... Non existant
MF - 5.8 Perkins in the 1130, V8s never sold here
JD - mostly 3000 series with the 5.9 Liter. In the 80s a few with the 6.6 liter were sold.

So to even start in this class, if you don't want to run "red", you are basically forced to either import a tractor from the US or put up with 300 (if that big) to 360 cui engines.

Back to the gear ratios and besids the fact they need to work on their performance:
As you have probably seen, most of them are on Michelins, Good Year or Kleber Radials, 38 or 42 inch, 650mm to 710mm wide. That's a lot more tire than the tiny and bias 20.8 x 38 tires you run in the US and which you can hardly find here. I think bias tires on farm tractors here were already on their way into history, when I was a little boy....

Here's a bit more tire speed in a 427 cui / 7700 lbs class from our dutch neighbours... to make up for boring you before Winking

All I can say is good luck getting everyone together. It sounds like you have a good start with you "region" to get everyone to come together.

I have been impressed with the Europeon equipment over the last 3-4 years especially with the resources they have available to them. Your raw material is totally different than what we have to work with and you guys are VERY creative.

I wish you luck with your endevour. My only input is 300 ci is 300 ci no matter the color, a p pump is still a p pump no matter the color and a 65mm charger is still a 65 mm charger no matter the color. Everyone has the same chance and has the same available parts as the next guy.

In the US there are a few groups that still want to run the A pump as a restriction of the class. IMHO it is just a way to seperate the class more. I have a friend that once said, "restrictions only make a guy spend more money to get around them." He is right to a certain extent. As a rule maker/promoter you have to decide how far one man can be in front of the other. The reality is the person that has the most money is going to have the advantage. NO DOUBT. But does he have a 25 foot advantage or a 2 foot advantage. Most competitors think "I can make up 2 feet in driving or gear or ??????" but if a person is getting beat by 25+ feet an a regular basis he will have a hard time believing that he can make that up. It is a fine line that a promoter/rule maker has to walk to make current competitors and future competitos feel like they can be a winner.

Good luck

Carl

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers February 28, 2010 02:40AM
You are very right with your statement.
That's why we not only have a limit in the engine / air, but also a limit on the return money. The other thing is, we also gave them very limited time at the "big" pulls. The "established" promoters, who run PS / MOD / SS / Mini can book ONE Hot Farm class. Those who do basicaly have them as "clowns for the lunch break" or to take care of the traffic at the end of the pull.
Other than that they also have the task to build up their own events.
So... not much money and very limited fame to gain. Stepping up is still easy and takes care of your transportation cost, while with a Hot Farm you usually loose money going to the pull ...

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers February 27, 2010 04:30AM
So why don't you turn it around; import these cheap stuff from Poland, like the Belarus, Zetor, Fortschritt and so. They have nice engine's under the hood with quite some displacement!

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers February 28, 2010 02:45AM
The Belarus and Zetors in deed make excellent pullers when playing in the same range of cui with a limited air flow.
The castings of the engines are often of very poor quality though.
A rather serious turbocharged Fortschritt engine (we have a FLEET of those tractors in the stock classes, as they sell for like 100 bucks and damn, do they have some low end tourque) is pretty much a no go, as the blocks always come apart.
The few Belarus and Zetors that were here, pretty much found their way back to the east for spare parts, too.
Funny enough, there seems to be more of them north and east of us than here - and we are right next to the old border!

Sascha, how`s that smoke eater work? Does it run it through water, Thanks.

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 05:01AM
i have been wondering that myself,does not look like they ever drag a tube with the sled.also looks neat still being able to see the smoke.

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 05:12AM
I can't tell you exactly. It runs water through it and that takes a huge amount of soot out, which is then dumped in that little vat on the sled pan.
On top of that "seperation" device sits a filter sheet, catching some more of it.
It's not what I would call the "best" solution, but combined with the extra ventilation they put in for that event and that "smoke barrier foil" under the roof next to the track it's possible to do it. It actually looks WAY worse on the video and on the track than it is in the spectator part of the building - and then for all the stock and "a - pump" classes the machine does the job.

BTW: Did anybody of you figure, that sled doesn't have a moving weight box, yet?

Some more - 4 bangers

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 12:37PM
I pull with SWOTPA & the best thing we did was get rid of the rotory & A-pumps. P-pumps straight across the board 2.5 inlet on the charger
& open rpm. You can't beat the reliability & consistanecy.


As for the civil war jim was commenting on, there is none. The callibre of pulling is the best its ever been.

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 09:52PM
I plead for forgiveness! never fails make a silly comment meant in jest and someone takes it serious! you guys run some of the hottest running tractors on this side of the border. gezz I hope it still safe to venture through our deep south? LOLConfused

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 03:33PM
Sascha, How does it load the sled, Does it use a Gyro, electric generator on the driveline,or etc...? That`s pretty cool.

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 11:55PM
The sled hydraulically lifts it's wheels according to the distance...

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 03:44PM
Are your pulls based on X amount of weight pulled a certain distance the fastest and if that is totally wrong please laugh out loud

Re: Question/Opinion - not only red/green limited RPM Farm Stock Pullers March 01, 2010 11:56PM
lol... no
Going by distance...

Can you get me in touch on how to build this type of smoke eater, I'd like to know more about it.
