Pullers Poll

I've pulled every running allis I got. My best luck has been with my grandpa / great grandpa's 53wd. It was rebuilt in the late 70's and probely has M & W pistons I don't know if it's 4" or 4 1/2" stroke. the 53 wd runs in farm stock 14.9 x 28 dyna torq II on 13" rims I just built a divison II wd45 puller . Or Around here a antique class. It has 15.5-38 tires.

Pull my stock Wd 45 diesel (turns 46 hp.) in 4500 farm with 14.9 x 28 tires, if I'm running at local pulls with people turning 60-80 hp. plus oversize tires I'm usually one of the last 2 or 3 in the class, in antique pulls can be anywhere from 1st (once) to mid class depending on what shows up.  Probably would do better if I'd put better suited tires (have R2 tread on new tires right now).  Also pull my D 21 in 12500 to 15500 (usually 13000 and 15000, but depends on class weights at each pull) it has 24.5 x 32 tires (new Firestones) and basically farm stock, the pump was turned 20% on fuel and stock rpm, but had it on a dyno this winter and it turned 185 hp.  Generally the D 21 is anywhere from 1st to somewhere midclass, generally midclass when running against souped up Deeres and IH's, but can usually beat a few of them and finish in the top 3 maybe 50% of the time.  The souped up tractors are usually running larger turbos, 3000 rpm, larger inline injection pumps, and sometimes cut tires depending on the track rules.

If I was going to pull 3 mile an hour classes with a d17 engine I would use a d17 tractor so I could run 38 tires and have the low side of the  power director to slow me down to 3 mile an hour.wc with 38 tall tires will fly in first gear if engine is turning any rpms at all.A tractor with tall tires and gears that will get it to the speed at which the rules at the pull are set will beat a tractor that has to get the speed from short tires because the gearing is to fast for tall tires every time.  my opinion.

  Bob, Short chain, short drawbar, long chain long drawbar. At what weight class does your sled go to a long chain?  Take it from there.

ALLIS FIELDS  i got some allis front weights for ya so u can throw them IH  ones away ...  lol

Is there a rule of thumb to shoot for concerning balance. (with one L)

Jm what you doing to the d17 engine in youre build up?

We run 14.9 x 24 tires on both of our WC pullers on the stock 8" rims (spokers on the 37 & pressed on the 38). Even the other A-C guys are running bigger wheels & tires than us, but we've made it work. The 37 is really just a good running stock WC with weight brackets but has won ALOT of Stock Class pulls @ 3500 & 4000 and a club championship. The 38 has an engine built similar to JM's that spins about 1900 rpms. This tractor has the slower hi-crop gears and we pull in 2nd or 3rd in the Modified Stock 4.5 mph classes. We just repeated as club champions at both 3500 & 4000, and also had a class win at 4500. This same tractor was undefeated @ 3000 in 2008, but we elected not to pull it that light any more, to give the smaller tractors a fair place to play at that weight. Dad was also club champion @ 2500 on his B, and I was 3rd over-all on my C @3000, losing out to two other A-Cs! At least out here it's true that Allis-Chalmers dominates the lighter weights up through 4500 lbs.! Kip
