Can anyone shed some light on the "cross-flow" IHC engines? Had a guy tell me the other day (IH mechanic)that you could build much more horsepower with a crossflow engine than other types? Correct me if I am wrong, but does "cross-flow" refer to the air intake on one side of the engine an exhaust on the other? This guy used to pull a 1206 IH with a twin turboed 414ci engine with water injection etc. He pulled in Vermont in the 80"s and was points leader and champion on the circuit for many years. It really ripped. He told my buddy that if he was looking to build a puller, that green was the wrong color. He made it clear that the cross-flow engine was key to good track horsepower. Would anyone care to comment on that?

Guys, thanks a heck of a lot for all of your comments. Certainly clears things up a bit. Jon

Back in the 80's in the NTPA super stock classes the IH's basically ruled the show. The cross-flow design was one of the reasons claimed. If my memory serves correctly (which may be suspect), one fella with a Deere actually somehow grafted an IH head onto his JD block. Called it the "Deere Harvester".

The theory is having the intake on the opposite side of the head from the exhaust keeps the intake air cooler and therefore denser to pack more air in the engine. I think it gets hyped up a bit, some JD engines are cross flow and some aren't. Around here 6030 pullers are beating the IHs. Cubic inches makes a bigger difference.

When you say "around here", where are you talking. I have seen a guy out of vermont pulling around here (New York, close to vermont and Canada, 30mi.) with a pair of 6030"s in the altered farm classes. They are ridiculously powerful and are great competition for the 66 series IH"s that pull in the same class. Think the name is Joe Vanderwoort. Not sure if I spelled it correctly. Thanks guys.

Yup, those tractors run good. He actually has an ad on the Photo ADs part of this website, selling a 5020 puller a while back. Yeah, Joe VanDeWeert.

Having the inlet and outlet ports on different sides of the head (cross-flow) allows the size of the ports and manifolds to be larger. High performance automotive gas engines are generally cross-flow. The cross-flow IH engine is generally top-dog for super stock tractors. I have seen Magnum pullers that are basically IH with Magnum sheet metal.

I dont doubt anything you say. But lets be serious, calling those tractors IH, JD, or any brand is kinda silly. Its just what color the paint is. Some of the 6030s that pull in the "farm" classes here are half aluminum.

I agree. I thought I could find the shipping wt of a 6030 but can't. Must be pushing 20000 lbs. Tractor pulling is a lot like NASCAR cars. They are just moving billboards for what ever the brand is. Underneith the tin, nothing is pure stock.

I could probably get you a shipping weight out of a operators manual later. Blue book shows 15,800 weight but doesn't say if row crop or standard or dry weight or what. Different front axle and rear wheel options would make a difference too.

My 5020 is 13300 lbs, not stripped and no ballast.(yes I pull it some) Gal around here has a 6030 puller, she says its down to 9800 lbs.

Low buget, I already sent email on this to Ron but the JD 6030 operators manual OMR55943, Issue K2 showed shipping weight of 15,800 for the standard and 14,680 for row crop. Also has note saying those weights were for one with turbcharged engine and equipment for average field service. Subtract 200 lbs. if naturally aspirated engine. Add 575 if has Roll-Gard and canopy. Add 1300 lbs. if has Roll-Gard cab. So all ballasted out with more weights a 6030 for use in the field could easily weight 20,000 or more. 6030 we had carried about 6320 lbs. of weights so was about 22,300. So yeah you guys & gals are pulling them down to almost half the original weight for field service.
