The needs of a puller are quite different then those of an average tractor user. I suppose they need maintained high energy at very high RPMs - just like in racing apps. There is more demand at high RPMs. I also figure they make their own systems for several reasons - and durability and cheap parts prices is among them. And one more thing . . . very often tractor pullers are more "hands on" and innovative then many tractor owners/casual tractor users I know.
From what I've observed here from people with Pertronix kits? Most posts I've read are about problem tractors that got magically "fixed" with these kits. Seems the tractors weren't right to start with so it's a poor "before and after" story. These posts also rarely state WHICH Pertronix kit was used. The standard Ignitor is quite different from the Ignitor II or III. One poster here mentions no problems with his 6 volt tractor. Well - that's doesn't tell me much either. My main stated concern is a low ohm (1.5) coil used on a 12 volt system that fries Pertronix Ignitor modules. Not an issue when the same coil is used with only 6 volts.
I've got many gas tractors, 6 and 12 volt with breaker ignition. I don't have any "problems" with any of them ofter then having to scrape, file, or replace points every 5 years or so. They start fine and run perfect as they are. That includes my 1010 Deere crawler, Deere 300 wheel tractor, HG and OC3 Oliver crawlers, Ford 4000 loader-hoe, Ford 641 wheel tractor, four Case VACs, Shaw R12, and an IH 3414 loader-hoe. If I was to install Pertronix on any of them - the only potential gain I can figure on is no more scraping/adjusting points every half-a-decade. When maintained, the tractors start fine and run fine - just like they left the factory. Kind of hard to improve on that.
Every time I hear one of these stories about "how much better my tractor is now with Pertonix" - it leaves me wondering. What was wrong with it before?
I've got no reservations about the benefit potential of a high energy breakerless system that is proven reliable. And maybe the Pertonix Ignitor II and III qualify. But as I see it -the standard Ignitor does not and that's all there is available for many old tractors.
I've got an open mind though. I'd like hear a standard Ignitor user actually post some details about what the old breaker system did NOT do, and the new Pertronix system does do.
My situation with my 1010 is different. I've got bad metal parts inside the distributor and used distributors are pricey. I can probably buy a Pertronix kit to replace my points rubbing block cheaper the fixing it. That's a problem caused by years of rust - not a design problem inherent to breaker-point ignition.

Today's Featured Article - Old Time Threshing - by Anthony West. A lovely harvest evening late September 1947, I was a school boy, like all school boys I loved harvest time. The golden corn ripens well and early, the stoking, stacking,.... the drawing in with the tractors and trailers and a few buck rakes thrown in, and possibly a heavy horse. It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
