The new KMB Xtreme Deer

The Runaway Deer Pulling Team from Raalte in the Netherlands, together with Charles Koebrugge from Markvelde, in the Netherlands, have built a completely new 7700lbs/3.5t John Deere component super stock tractor during the last winter. The Runaway Deer Team around Paul, Wilco and Jos Broeks started with tractor pulling with a Fiat stock tractor in 1988. Shortly after Paul started with his Fiat tractor on local pulls in the Netherlands, his two brothers Wilco and Jos also purchased a Ford 4000 tractor for stock pulling. On the Ford tractor was a bigger fuel pump on the engine and a set of new better tires mounted, which made the Ford 4000 almost unbeatable in his class on the local pulls. Over Wim Jansen (former owner and driver of Deer Hunter and Mannheim Magic) they purchased later a John Deere 4455 stock tractor. After the old Fiat was sold, the 3 brothers still competed with the Ford 4000 and the John Deere 4455 on local pulls.
In 1995 the Runaway Deer Team and some other teams searched the contact to the NTTO in 1995, to find a solution for a new diesel class. In 1996 the pro stock class was introduced into the NTTO B-Division (now NTTO National). The Dutch Team together started with 2 other teams in that new division. In 1998, the Runaway Deer Pulling Team won with their John Deere pro stock called ''Freriks Werken Runaway'' their first dutch championship title and finished in runner up position at the first European Championship for pro stock tractors in Great Eccleston, Great Britain. After some unhappy things, the team and 2 other teams switched into the NTTO A-Division (now NTTO Grand National) in 1999. They competed from 1999 - 2002 in the Super Stock class against the dutch top alky burner tractors because the A-Division had no own pro stock class during that time. During that time the pro stock machine received a facelift, the old John Deere 4455 hood and fenders were replaced by a John Deere 7700 hood and fenders. After 4 seasons in the super stock class, the Dutch Tractor Pulling organization introduced the pro stock class in the A-Division too.
The 2004 season was a very successful season for the Runaway Deer Team, they won a couple of dutch championship events which brought them the 2004 dutch championship title in the end.
During the winter of 2005 / 2006, the Kawe Runaway Deer was completely rebuilt and got a lot of changes. The pro stock received a new lighter tube frame, with a revised John Deere rear end and new John Deere 7810 hood. They competed with the tractor from 2006 until 2013 in Dutch Championship and finished 2 times in 2006 and 2007 in runner up position with tractor in the dutch championship. They also competed with middle success in the Euro Cup. During that time the team also got with the company called ''Kawe B.V.'' a new main sponsor on the tractor.
KAWE is a family-owned manufacturing and trading company, specialized in friction technology and was founded in Raalte, Holland in 1970.
For more than 49 years, the company is a leader in the development, production, and distribution of friction and brake materials. In the course of this period, the KAWE brand name has earned a worldwide reputation. Their activities are being divided in a 3 market segment, in passenger cars and light commercial vehicles (including classic cars and motorsport), Truck and bus and Agricultural.
After a tough 2013 season, the 3 brothers decided to build again a new tractor this time a new component pro stock tractor for the 2014 season. The component tractor received a Domex steel wedge frame with a chrome-moly roll cage, a sheet metal rear end with a Humpco differential and ZF planetaries, a Kippley transmission and a John Deere 7920 hood. The frame and rear end for the tractor were built by the Zeinstra Pulling Team from Ouderkerk aan de Amstel in the Netherlands.
The John Deere hood and fenders were taken over of the old pro stock tractor. First, they wanted to have a new John Deere 7R hood on the component tractor but because of the high costs for a new hood, the brothers decided still to use their old 7920 hood for the new one.
Under the hood of the tractor working a turbocharged 6 cylinder John Deere engine with 8.3l on diesel fuel. The power plant has a machined JD block with a flowed JD 55 Series head, a billet crank with KMB (Koebrugge Metaal Bewerking B.V.) rods and pistons, a homemade intake and exhaust manifold, a Diesellandia (Herlevi Pulling Team)billet turbocharger from Kalavia in Finland, a billet CDS (Columbus Diesel Supply) diesel fuel injection pump, a homemade intercooler and a Racepak data logger. The engine should make around 2500hp at 5500rpm with this setup.
The component pro stock debuted in the spring of 2014 and is still to find on the top of the lists in the international raking of the pro stock division. In their very first season with the new component tractor, they won the 2014 European Championship title in Bouconville, France. More success followed during the years, runner up at the 2017 EC in Stroe, the Netherlands, 2 times runner up in the Euro Cup point standings in 2018 and 2019 and a lot of wins on national pulls in the Netherlands.
But also Charles Koebrugge isn't an unknown person in the European pulling sport. Charles Koebrugge is the owner of the company called ``KMB Koebrugge Metaal Bewerking B.V.´´ in Hengevelde, the Netherlands. Charles machining in his company pulling parts for different pulling teams in Europe. He started with the building and machining of pulling parts in 1997 for a local guy with an old Ford tractor which competed on local pulls in the Netherlands. In those 22 years, he has developed and built pulling parts for international teams like Zapo, Zeinstra, Midnight Deere, Runaway Deer and many more.
His company ''KMB'' is a modern supply company, specializing in single piece manufacture to serial work. The main activity of his company is the production and processing of new and existing mechanical components, mostly machine parts, in the most diverse types of metal and plastic.
The plans to build a super stock tractor existed in the heads of the Broeks brothers for many years and Charles Koebrugge also had an own plan for a super stock tractor. After some talks the Broeks bros. and Charles decided to build together a new John Deere component super stock tractor. In the fall of 2018, the dutch team started to build the new tractor. First plans were to built a new Domex wedge frame for the new tractor but then came an offer from Brent Payne, owner of the GMS shop in Hamilton, Ohio, for a complete tube chassis which was used in the Agco DT225 component super stock tractor called ''Galot 1'' of Earl and Peggy Wells from Benson, North Carolina in the USA. On the same day, they decided to purchase the chassis from the Galot Team. In the package were also the complete rear end with the planetaries and the transmission.
The Galot 1 chassis has a custom made tube frame with a custom-built roll cage, a Kirkey Racing seat, a hydraulic power steering, and a sheet metal rear end.
The driver's position on the tube chassis is more forward and the center of gravity is lower compared to the Kawe Runaway Deer wedge chassis. The Team hopes to have a good balance on the Dutch and European pulling tracks in the future. The sheet metal rear end has a billet Humpco aluminum center section with a billet Humpco differential, a specially made ring and pinion gear, custom-built half shafts and Franklin magnesium planetaries carrier housing with custom-built Humpco planetaries.
The chassis was built by Brent Payne and the people in his company called Gene´s Machine Shop (GMS) in Hamilton, Ohio.
The transport of the Galot Chassis from the US to the Netherlands was arranged by Braakman Service and Parts from Laren, in the Netherlands.
The new component super stock tractor received a new John Deere 7230R hood and lightweight fenders from K&K Specialities in the USA. The new hood comes from the current John Deere 7R series. The 7R Series was introduced by the American company in 2011 and replaced the old John Deere 7030 series. The 7R is currently available in 6 different versions as 7210R, 7230R, 7250R, 7270R, 7290R and 7310R. The 7230R is powered by a turbocharged inline 6 cylinder John Deere PSS engine with a displacement of 6.8l on diesel fuel. The engine in the tractor has 190hp with a maximum torque of 1077Nm at 1600rpm. The tractor is available with 2 different gearboxes, with the Auto Powr or the e23 PowerShift gearbox. The biggest one in the series is the 7310R. The machine was introduced in 2014 and has a bigger engine with more horses compared to the 7230R. The 7310R is powered by a 6 cylinder John Deere PowerTech PSS power plant with a displacement of 9l on diesel fuel. The engine has 4 valve head with a high-pressure Common Rail injection system and a VNT turbocharger
(Variable Nozzle turbocharger). The power plant makes 352hp with a maximum torque of 1452Nm at 1600rpm.  
The John Deere 7310R should build according to John Deere only in limited quantities.
John Deere also has announced this fall the current 7R series will be replaced by the 3rd generation in 2020. The 3rd generation of the 7R series was officially revealed at the 2019 Agritechnica in Hannover, Germany this month. Back to the pulling machine.
The hood on the pulling tractor can hydraulic lifted up for some checks after the pulls or in the workshop. All the aluminum sheet metal work on the hood and the fenders were done by the team himself.   
For the new ride, the guys purchased a set of used cut Firestone Puller 2000HP on polished Midwest aluminum rims. The tires with the rims come from the Zeinstra Pulling Team
Almost completely new is the drivetrain of the super stock tractor. The tractor has a used Profab transmission, a new Crower centrifugal clutch with a billet flywheel and steel bell housing built by the Zeinstra Pulling Team from Ouderkerk aan de Amstel in the Netherlands.
Between the transmission and the clutch working a homemade custom-built steel driveshaft to bring the power to the rear axle.
The new KMB Xtreme Deer is powered by a turbocharged 6 cylinder 6076 John Deere engine with a displacement of 10.5l on alcohol fuel. The 6076 engine comes off the John Deere 7700 and 7800 stock tractors. The John Deere 7700 and 7800 tractors were built between 1992 and 1997 in the John Deere plant in Waterloo, Illinois, USA. The 6076 power plant in the stock tractor is a water-cooled engine with a cross-flow cylinder head, light metal pistons a Bosch multi-piston distributor pump and exchangeable wet cylinder sleeves. The powerplant in the 7700 John Deere has 150hp with a maximum torque of 607Nm at 1255rpm and in the 7800 it has 170hp with a maximum torque of 716Nm at 1302rpm.
On the pulling engine is only the block still John Deere the rest of the parts are custom built. To increase the displacement of the engine the block was bored up from 7.6l to 10.5l. 
The power plant in the KMB Xtreme Deer received a machined JD 6076 cast-iron block with new Darton sleeves, a machined billet steel crankshaft with billet aluminum rods and pistons, a used VSP billet aluminum cylinder head from the Zeinstra Pulling Team, a billet steel camshaft by Jan Burgraaf (New Generation Pulling Team) from Loosdrecht in the Netherlands, a homemade intake and exhaust manifold, 4 billet Holset HX82 turbocharger, a CNC-milled aluminum engine plate, a VSP (Veldhuizen Special Products) fuel system with a Waterman fuel pump, a homemade fuel tank, a aluminum oil pan, a Aviaid oil pump, a MSD 8 Plus ignition and a Racepak data logger. The parts like the rods, pistons, crank, engine block and the engine plate were CNC-machined in Charles Koebrugge's company "KMB" in Hengevelde, the Netherlands. 
The alcohol fired John Deere power plant with the 4 charger setup should make around 3500-4000hp. The engine was built up by the Zeinstra Pulling Team from Ouderkerk aan de Amstel in the Netherlands. The engine is basically almost the same as in the Zeinstra New Born Deere or in the Green Gangster Deere. 
The new component super stock had its maiden voyage at the Beachpull in Putten, the Netherlands this summer. In the super stock competition, they had some troubles with the boost sensor of the engine, that's why they brought the sled not away from start. Later that day, they made a successful test pass in front of the Keep Moving Orange sled. The rest of the season was more or less a learning year for them to understand how the new tractor and the alcohol system on the engine working. 
But the last runs of the season were pretty impressive, as the runs at the German Championship round in Kalkar and the Dutch Championship event in Lochem. One is sure the new KMB Xtreme Deer component super stock will be a top contender for the future.  
For 2020 they have planned to compete in the Dutch Grand National Championship and maybe in the Euro Cup.

New Light Unlimited from Kentucky

From Georgetown, Kentucky in the USA, the Young Blood Pulling Team around Jason Gibson have built a new tractor for the 6000lbs light unlimited and the 7500lbs modified class during the last winter. After many years in the 2WD truck class on KTPA and NTPA Grand National circuits, the team had decided to switch to the modified tractors. The Team around the owner and driver Jason Gibson started about 19 years ago with pulling in the 2WD truck class in his home state Kentucky.
Jason's crew consisting of his girlfriend Sara Carter, long-time friend Todd Stone and Sam Winkle and friends Eric Prewitt and his wife Johanna.
The first considerations to build a mod machine came in 2017. After 17 years in the 2WD division, it was time to switch classes just for a different new challenge. Jason competed with his Young Blood two-wheel drive truck his last full season in 2018 before they started to build their new toy.
But the two-wheel drive truck isn't sold yet, they still own the truck and still can run at local events from time to time. The truck is powered by a Miner Bros. V8 Hemi engine with a Fowler / Kobelco 14-71 blower on methanol fuel.
The crew started with the new project in the winter/spring of 2019 in their workshop.
The chassis of the modified ride has a steel wedge frame with a 3 bar chrome-moly roll cage, a Kirkey Racing driver seat, a rack and pinion steering, steel wheelie bars and a Rockwell SQHD rear end.
The Rockwell rear end has a Crutchfield Machine billet aluminum center section, with a Humpco billet aluminum diff, a Rockwell ring and pinion gear, Engler Machine & Tool Franklin magnesium planetaries carrier housing with 4-gear Crutchfield Machine planetary gear carriers, Engler Machine & Tool brake calipers with Mico Master cylinders and magnesium brake rotors. 
''Crutchfield Machine'' is the company of the former super stock competitor Robby Crutchfield from Liberty, North Carolina. Robby competed many years with a 640cui V8 Perkins alcohol powered Massey Ferguson 8280 component super stock tractor called ''Brutal Force'' in the 8000lbs super stock open class on the NTPA Grand National circuits in the past. Currently, he's building pulling parts for other teams in the US. 
The whole chassis including the aluminum fenders were built by Scott Tedder of Tedder Pulling Performance from Marion, Indiana. But it isn't a new chassis. Scott built that chassis side by side to his current Mr. Twister modified tractor in the winter season of 2013/2014. The Young Blood Team purchased the used Tedder chassis without the engines from Paul Knootz of Welcome, North Carolina. Paul Knootz competed with his tractor called ''Joker'' mainly in the light unlimited and modified division on the NTPA GN circuits from 2014-2017. Paul also ran for a single time in Benson, NC with 4 Hemi engines in the unlimited class in 2017.
Also in the package were the rear wheels and the whole drivetrain of the tractor. The rear wheels on the mod machine are a set of used cut Firestone Puller 2000HP tires with polished Midwest aluminum rims.
The completely new vinyl graphics on the fenders were done by Fast Signs from Charlotte, North Carolina.
The drivetrain of the tractor has an SCS magnesium reverser with a billet steel driveshaft between the reverser and the crossbox and a Modern Machine crossbox with billet steel gears. The crossbox on the tractor is not only built for 2 engines. With a dropbox, it's possible to run with 3 or 4 Hemi engines on the mod machine. Each engine on the tractor has a Molinari centrifugal clutch with 2 discs and is protected by a Browell aluminum bell housing.
The new Young Blood Jokers Wild is powered by 2 blown 526 Keith Black V8 Hemi engines with a displacement of 526cui on methanol fuel. In the 7500lbs mod class, they put a 3rd Keith Black Hemi engine on the tractor to increase the horsepower.
Each powerplant on the chassis has a Keith Black Stage 10 engine block with billet sleeves, a 4.5 Winberg billet steel crank with BME aluminum billet rods and Diamond billet pistons, Dart fuel aluminum billet heads with Keith Black Stage 5 rockers, aluminum valve covers, Dan Olson Racing exhaust headers, a billet steel camshaft, a Fowler / Kobelco High-Helix 14-71 blower with a Bohr Hammer carbon fiber injector scoop, a MSD 44 Pro Mag ignition, a Aeromotive fuel pump with a aluminum fuel tank, a RCD oil pump and a Dan Olson Racing aluminium oil pan. The 3rd engine for the 7500lbs mod division has the same setup as the front 2 motors only the carbon fiber scoop is different compared to the other 2 motors.
Each KB engine on the tractor should make around 2500-3000hp with this setup.
The 2019 season was a learning year for the whole team to find all the right setups for the tractor and for the engines. But with some constant results during the year, the team from Kentucky finished on a well-deserved 3rd place in the NTPA Grand National point standings in the light unlimited division. The Young Blood Team also competed on 3 events in Tomah, Wisconsin, Hagerstown, Maryland and in Bowling Green, Ohio with 3 engines in the 7500lbs mod division. The best result in the 7500lbs mod class was the 5th place in Hagerstown.
For the upcoming season, they have planned to replace the 2 front Keith Black Hemi engines by new better and more powerful Hemi engines. But it's currently not sure which engines will receive the tractor for next year.
One is sure Jason Gibson and his crew will compete in the NTPA Grand National Championship of 6000lbs Light Unlimited division again and on some events with 3 Hemi engines in the 7500lbs mod division in 2020.
