On the tires, in the mod rules, "no tire wider than 15.5 " Please define that. Is that diameter, or footprint or what? Would (say) a 16.9 X 28 be legal, because it has a smaller footprint than a 15.5? AC

A 16.9X28 has a larger footprint than a 15.5X38 according to the Firestone Traction Field and Road chart. 15.5X38 = 189 sq in, 14.9X38 = 200 sq in, and 16.6X28 = 209 sq in. Not a lot of difference, but you have to draw a line somewhere. Mike

Im not on the rules committee, but had a similar incident a few years back with a WC that had 16.9 tires. They made him take the 16.9s off and put on 14.9. Basis for the desision was, the 14.9 is an available tire for retail sale. (still being made) In not for it or against it, but thats what happened a while back. Maybe some others can speculate,,, Chad

Well, ideally, I would like to run 16.9 34's or 16.9 30's. A 14.9x38 on a WC is getting things moving pretty damn fast for 4.0 in first gear, and way too tall for high first, so I dont know what to do. Oh,, BTW, Thanks for the rules! I'll send ya an email about the other stuff...AC

The guy that runs the WD in our club used 13.6 and 12.4 X38 on both of em, and he did very well over the years. Chad

AC - Stick a D-17 engine in there, then you can get 300 more RPM's!!! How's that sound for fair?

Sounds great ... ;) I mena, I pull an H too (all my friends are laughing right now, cause technically its in the shop for the last 1.5 years) and I dont understand the RPM break between the H ans SH. And I really dont care, either..I was just bringing up the subject for discussion. In low MPH, I am not too concerned with how hard I can turn my motor anyway. Its just that poor little WC gets raped when it comes to RPMs. (violins please) I dont think there is but one other Allis in the club, and I've never even seen it pull, just sit on the trailer. I'd like to see it run, just to see how it does. Anyway, I think the D 17 getting more RPM's didnt hurt anything, because you arent getting one in 3500, especially of you are an average size, or even below average size red blooded male. That leaves maybe 3750 and 4500. You can build anywhere near the cubes out of that like you can the M or 88 or U, 44, or even the 77(I guess) so might as well help it out a bit. And really, I dont think too many people can complain too much because how many people do you see pulling a 17? Kurt Hamel and who else? I think its the only one I have ever seen, oh and Brown's, out in Iowa.

Id have a problem with a WC running D17 rpms. I look at it like this,, the next in line production model, which would be a WD, thats a one step up from stock, not much of a difference, but its a change none the less. If the WD45 rpm is the same as the WD, then lets call it a 45, BUT, if the 45's rpm range is higher than the WD, then thats considered a TWO step jump. Then, lets throw in a D-17,,, if the Wd and the WD45 rpm are the same, then the next step is the D-17, that makes it a THREE step jump. If the 45's rpm range is higher than the WD, then that makes the 17 a FOUR step jump. See, years back, a huge battle was fought over this subject,,, the AC pullers wanted the 17's rpm range, and did not even consider the other makes and models that they pull against in the class. So in MID stream, the rules was changed to allow the WC to run the 17's rpms, and the others remained right where they should be. When the others complained, they got the cold shoulder and was told youll have to bring that up at the end of the year meeting for rule changes,,, So from that point on, the others were getting hosed, till they upgraded all of the rpm charts to match the upgrades they GAVE the AC's. The same battle on the 460 and the 660 rpms happened, Olivers running the 310's wanted the 310s rpms instead of the 77 or 88, etc etc etc. Long story short, if the WC runs the 17's rpm, you can bet, that My H would be set at 350 rpms, +10 or 20 or 30 percent from that, that makes it fair, its either that, or we keep the rpm percentage rule to that particular model. In my case, Im stuck at 1995, at 10 percent over H rpms. Now, the AC pullers may think Im nitpicking,, well, whats good for the goose, is good for the gander, but at the time, they thought the goose was so much better and to heck with the gander, its not that way today, but it sure was dirty pool when they pulled that political crap to get their way. Also, tractors that are half aluminum, have no place in classes under div 3, I would even say div 4, but too many have class jumped and so many did it, they let it go. That kind of modification to me is considered a frame alteration. And what classes do they allow frame modifcations??? I can go on and on, but Im sure this will spark a huge argument, names called, and toes stepped on already. But its my opinion, dont shoot the messenger. Chad

What are you doing using NATPA lingo there PudS? Shouldn't you be using terms like Super-Prostock, Unlimited Modified Stock, and Super-Duper Farm Stock? They could give your H MX450 rpms and it still wouldn't be enough to beat anyone!

AHH! Well, there is several OTHER references I can use in reguards to NATPA,,, if the shoe fits, put the darn thing on and wear it! the funny thing about lingo is,, is the popular classification that is most known all over. So what? Never brought up the name NATPA though. What about other clubs that use NATPA rules but are NOT NATPA sponsored? I can be talking about Bobs world of pulling association! Can be anybody Im talking about. But, if the guilt is gathering in your craw,, you need forgiveness, you will not find it from me! Chad

That you are really this crazy in real life or is this an act that you try to perform on here? All I can say is that if you were in my local club, I think I'd go buy a boat!

Id like to someday, build my own sled, with all the bells and whistles,,, some lingo, is that pulling sleds, are sometimes called "Boats" and Ive seen some yachts out there! But thats my idea of a boat. Maybe yours is to go out on the water. if thats your thing, then the shoe fits, wear it! I think thats cool. I cant swim well, so Im a dry land kinda person. Ive been out on the coasts, and seen some beautiful scenes in the sunset, big ol ships going somewhere. I had a schedule to keep driving a W-900 KW with a 48ft flatbed inbetween the lines. I sometimes got there a bit late, but I got there, and in one piece, each and everytime. Lucky, I guess to be lucky to make it home whenever I got the chance. During that time, I had alot of time to think about where Im going, I know where Ive been, but where do I wanna go? Well, I want to go pulling. These days, I cant travel far away from home, just too much on the plate to take the time we used to. So local clubs is all I have, and no winter time events to go to. And yes, it can drive a puller crazy. But, Ive had time to think,, I know the direction i am aiming for, and thats to drag our sled's weight box as far up the rails as I possibly can, till it dont go no more, and thats a full pull in NCIATPA. In 15+ years, over half my life in pulling, I have yet to trip the full pull light on that sled. Thats my goal, my act, or my game. Call it crazy, call it what you want. Just load up and come to pull on that sled, it does pull very well! 2 hooks for 20 bucks, for members, 4 or 6 hooks max,,, You get the chance to meet some really good people!! Pullers, Ive known for years, and know, that they are some of the best in the area, and this club covers alot of ground! If you have pulled out on the winter circuits, you may have seen them. They may have went home with your entry fee. Ive seen em do it. HAHAHA! Its even more fun to try and win it back the next week. If you think its an act, then yes, I am just playing my part, this is a sport, a game, something to do. So if you want to go out on the water, and miss all the excitement, then have fun. Thats something to do as well!

Oh yeah, I'm alllll l for WC running D17 RPM's !! Put a big smile on my face! But I dont think its fair to everyone. Cause then an H could run 350 utility RPS's and you'd be all smiles..heck with the pistons and crank I have laying around, I'd be all smiles!

No, its give and take. A WC should not run D17 RPMs. I agree. I also think an H should run 350 RPS's, an M 450 RPMS' 88 runnin 880 RPS etc just to eliminate confusion or mis-interpretation.

That H needs to be put back together man!! I got one thats been sittin longer than that! LOL! Getting it ready though,,, Just watch the speed horn, and go pullin. Worry bout the rpms till you beat em, and they come after ya. may sound dishonest, but hey,,, what the heck. HAHA! Chad

Different machines, different rpm ranges for lots of the same type of engines. Like the H and Super H, 1995 for the H and 2050 for the Super H. Kinda different, but the same. Chad
