I know that this is a cut/paste, but here's my opportunity to display my dorkiness for the corrections dept.

* Everything between 250 Spirit and 500 Superchief on the list (inclusive) have poly bodies.

*The "400R" is listed twice; To my knowledge there was only the ST/400/R

*The list is missing the ST/295, an ABS bodied machine.

*I've seen one (only one) 400 Thunderchief. (It was just recently re-dragged out back of a dude's house after sitting out front for about a year or so. It'll sit there for the next 30 years, too...)

The fastest and most powerful is the Superchief with the 484 Chaparral. No contest. That includes ALL AATVs, not just Attex.

As far as popularity goes, I have no idea about production numbers. I sure see a lot of 400 Chiefs and Superchiefs, though. I'll let others chime in. I'm sure there's SOMEONE out there who wants to add something....

Okay, here goes SOMEONE, just to show Hydromike he doesn't have the corner on the dorkiness market.

ST/400/R was two different models as far as I can tell from the old Attex lit that I have. The original was a first generation machine with a 400 CCW twin. I know these exist because I have one. The other was made in 1971/72 and was the same configuration as the ST/295 and ST/400. It came with a JLO rockwell 5-port 400 and twin carbs. I've seen this on the model lists from the factory but never seen the machine, so whether or not it actually made it into production......????

As for the 400 Thunderchief; if I hadn't seen the thing I'd be really skeptical. If it was a cut-and-paste job with the decals, it was a fine job.

Don, you've never seen a 71-72 400R? That sounds like a challenge for me to go on one of my 6x6 scouting adventures and find one out in the rural hills of East Nowhere, USA!

[Mike]

Thanks guys, I edited the list...does it look right now?

As for the Superchief with the 484 Chaparral, which one is that? The 500 Superchief?

What about the 400 Thunderchief? Is that the 440 Thunderchief on the list or is that completely different?

I sure am glad that you guys are dorks

[Don]

Jeff- Yes, by all means find me one! Knowing you, there'll be one at your place next time I'm up

Mike- Yes, the only engine to my knowledge that ever came in the Superchief was the 484. The 400 Thunderchief may be an anomaly and never actually in production, but I don't know. I've never found it on any list, but seeing is believing. The 440 Thunderchief was a popular model and a pretty common find.

I've read somewhere that Attex held 60% of the national market for years. Considering the number of manufacturers throughout the industry's heyday, that's a real feat. That would also explain why the yellow machines are so plentiful.

Don, would you say that the bulk of Attex machines remained around PA for the most part? I remember the first time I saw an Attex around the Buffalo was back when I was just 16 or 17. I had seen many Maxes before that though. The next time I saw an Attex was in 2004 or 2005 and it was in PA. I'd say that 90% of the Attexs that I have bought were from PA. Only one was in NY.

[Don]

I'd assume that the closer you get to the manufacturing plant, the more old machines you're going to find, but I've picked up Attexes pretty far away (I won't say how far: people would think it a little strange). I think there were more dealerships in PA and OH than anyplace else, so probably more were sold there.

Can we start a sound off for Attex model, serial #s, and year if known? Mine is a ST/400/R, serial# 2232(per dash sticker), year `70-`71 ????

The Max owners are having all the fun

I was enjoying the list above of all the different models available, amazing.

I'm out. This would force me to count, and my therapist says enumerating my problems isn't a good thing.


I don't think it's a bad idea at all. For those unfamiliar with Attex serial numbers, second and third generation Attex machines have the "serial number" stamped on the rear, right, upper frame rail. There is a smaller set of numbers (sequential frame number, supposedly) and a larger, two digit number (74, for example) signifying the year. The one clincher is that the year stamped doesn't *necessarily* denote what year the entire machine is; it could be a year or so off. The number really only determines when the frame was supposedly made. A couple different sources have noted that some frames sat around for a year, two or more depending on production demands.


It'll be interesting to see all of the data as the list grows... I'll try to get some of my numbers this weekend.

"I'm out. This would force me to count, and my therapist says enumerating my problems isn't a good thing." Your brain hurt when you count like it does me? Thats why I only keep one at a time LOL

I'm still on one hand, no need for therapy yet. Counseling on the other hand, maybe?
