Just curious how different clubs set up there engine rules.

In my area they have made a rule that you can run any engine from same manufacture as long as it bolts in with no mods.

So they allow IH to run red diamond, oliver 310 , MM 800 block and heads.

I am not one to complain, but it sure seems bias to me.

Well around here these are the dominate tractors. Red diamonds and olivers always in the top places. One of the MM had 670 cubes he won his class at idle in road gear.

But they will allow you to run a d17 engine in a 45? Uhhh hmmm. Why not a 301? Or a F2 diesel?

Or how about a rule for all that just puts cube limit or hp limit what ever engine you want? I sure would make it more economical.

I think they are ruining the sport, if you run a different brand you are at a disadvantage.

The national rules say you have to run a stock block. That seems fair.

I am putting a Detroit diesel in mine, we will see what happens when I pull it off the trailer. LOL

What rules do your clubs run with?

The pulling club I belong to has a engine rpm limit, for each brand of tractor. Rpm limit is for that model of tractor no matter what engine is in the tractor.

Our club only allows a stock engine for the Antique (1939 & older) and stock block for the stock classes. For the open classes you must have an engine of the same number of cylinders that will bolt in without modifications and running on the same fuel. No gas 6 cylinder Wd45s. For turbocharged tractors 4000 lbs and under there is a 280CID limit. 4500-5500 pounds a 414 CID limit above that a limit of 466CID. N/A engines are not restricted in the open classes.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

We have mostly antique pulls near here, where I have attended. Now I am sure there are many engine mods and swaps that bolt in to give the owner more HP advantage too. I had fun last year with my fresh WD45. Was hoping to get this (WZ) old WD with the Gleaner Z code, in some classes but it doesnt look too good right now.

I am not a engine/ HP builder. To old to start chasing that now. Just tryin to see how these old orange tractors hold up. I think if the tractors in the calss are all pretty much stock the Allis WD series does pretty well.

As for rules. We have one pull that checks RPM. The rest its only drawbar height and tractor/ driver weight for the class.

Still have fun after a couple years playing this game.

Big competition, well not for me, there will always be someone that will out do ya!

Regards,

Chris
