I am building a farmall h to pull in the 5,500lb stock and 6,500lb stock class. What do i need to do? I know i need a wheelie bar and weight bars. In the stock class what can i do and what should i do. What would everyone recomend for a pipe. My dad claims i need the backpressure from the muffler but every one i see except for 3 tractors just had crome pipes. This is my first tractor and im 15 so any help is deffinatly greatly apreciated

You are gonna have to do some engine work to pull that weight class, and not stall it out all the time, most H "s wont pull 4500 with out stalling out. Now, I am not at all saying that an H cant pull 5500-6500 lbs, with the proper engine work,, would be fun to beat the M,s or what have ya,, at their own weight. I have a 70+ hp H that we pull in div 2-3 style pulling, in low gear,, you cant stall it, not even at 6500, with 15.5X38 tires. wont even lug the engine. If I find it I will post the picture of it at 5500, man, there is weights everywhere on it,, LOL maybe stick with under 5000lb classes till then,, start light, maybe 4000lbs,, and work your way up, on the hitches,, and wheelie bars,, build wheelie bars strong,, dont skimp on those,, the hitch,, you could go with the modified specs,,, but if it is stock,, the stock drawbar assembly will pull fine in a farm, or div 1 class style of pull. give it a good tune up,, plugs, wires, cap, rotor, fresh fuel, that would be a good start for ya,, will keep ya busy for a while,, go get a I&T shop manual for the Farmall letter series,, those books are very good for learning the tear down, and rebuild process of anything you tackle with your H. Hope this helps,, ChadS

Its odd what your saying becuase i saw a stock h pull in the 5500 and 6500 lb class. I will be running 13.6 tires. O yea and its "stock", can i have mods done to the motor, i have a complete rebuild kit on the way, have new rims and tires, and im trying to figure out what to run for a exhuast pipe. PS. 5500lb stock is the lowest weight class their is, its filled with mostly john deere 2 cyl tractors, Some 4 cyl, and a few 6 cyl. And as far as i know we are not allowed to run cut tires and there is a 3-1/2 mph speed limit. And there is also a 6500 unimited stock (unlimited means no speed limit) class that i will run it to. Im guessing the motor has to stock.

Well, I have pulled H farmalls for over 13 years,, and no it is not odd,, it is true. Odd thing out would be that the H you seen wasn"t stock,,, maybe onthe outside,, I have an H putting out triple digit HP,, and still is in stock appearance.,,,, H"s have good potential,, just takes a little knowhow, and a bit of $$ to make em run better.

It takes a good "stock" M to pull 5500 and 6500 on most tracks. Bet that "stock" H is a smidge hotter than you think.

Well this is my first tractor for tractor pulls, im just basicly saying that it is a stock class. If the 2 cyl deere were pulling and not doing half bad why is it my 4 cyl h wouldnt pull? This event i will pull at is just like a bunch of farmers getting togather for a friendly competiton. As i said before there is a 3-1/2 mph speed limit, dont know if that makes a diff. But one thing that is confising me is that a 2 cyl deere even went in the 8500lb weight class!! It was really loaded with weights and it did horible (150 ft) But as i said, its just a bunch of people having fun, luckily if the winning prize is $20.

That 2 cylinder John Deere probably has twice as many cubic inches in it's 2 cylinders than your H has in all 4! Not to mention the tremendous torque that a low rpm 2 cylinder makes. Add to that the creeper gear if it was so equipped and the Deeres can pull in pretty heavy classes compared to their red equals. They may do it slow, but they will do it.

I don't quite understand much of the "a stock tractor won't have enough power to pull at that weight" stuff that you see on here. Tracks are made from different materials in different regions and sleds differ from pull to pull. This being said, you here a lot of "regional" advice that may not apply to where you pull. Does your sled use a long or short chain? How high is the chain hitched to the sled? What type of soil is the track? (clay, sand, mica, silt, hardpan, etc.)

Where I'm from, you could probably pull that stock H up to 5000 lbs. The best advice is to see what it weighs now and go from there. Before you buy a pile of weights or load the tires or whatever, pull it light and progressively try heavier classes maybe borrowing weights to try it out.

Two cylinders run heavy classes because of crepper gear not tremendoes torque, I saw a R and 80 power out and die at running pull at 9000, if you are running under 1 1/2 mph you shouldn't have a power problem. On a power track a stock H will have trouble at 5000 lbs, better stick to 4000, 4500 on a loose track you could go to 5500lbs. If the H had firecraters pistons and some other work it would make a good puller but you will have to stay light.

I may not know much, but I sure can do simple math! Take a look at the Nebraska test results. The numbers don't lie. The late model JD A running on gasoline made 38 hp @ 975 rpm. Super H tested at 34 hp @ 1650 rpm. Do the math and you will see that the Deere makes roughly 2 times the torque of the Super H, but only 4 hp more. Let's take it one step furter. The JD B at only 27 hp makes 50% more torque than the Super H with 7 less hp. Furthermore, the 2 cylinder will continue to lug at half of it's peak rated power while the IH motor will hardly have anything left at even 975 rpm.

I've been wrong before, but I would say that 100% more torque could certainly be considered "tremendous".

Lets go tp a power track, 9000lbs JD 80 runs about 65 hp IH 450 makes around 50 hp, I watched the 80 power out and die and the 450 in 1st TA back spin out, where is that tremendous torque hiding.

Once again i will state, it is a REALY, loose track, and the smallest class there is is a 5500lb stock 3-1/2 mph limit.

Like I said before, you absolutely have to make a few pulls to learn how your tractor behaves on your track. The opinions that you are getting (including mine) are just that, opinions not absolute facts. On a loose track you may not power out and then again you might. We have no idea how well your tractor runs.

Give it a whirl and let us know how it turns out for you!

They use long chain, the soil is very dry, loose, and dusty, And the sled is very old and they dont load the sled with any weights for these classes.

years back,, I went to case IH and got one of those long chrome curved stack they sold at the time,,, looks like the ones on the 88 series IH tractors,,,, I cut it in half, made 2 stacks, the straight pipe part, went on the big engined H, and the curved one went on the other H,, I would say they are about 24 inches long,, and 2-3/4 inches in diameter. sounds good,,, and high enough to keep the fumes out of my eyes,,, Chad

I have a gas head and manifold. And one more thing i should say about the track is they dont water it or pack it so its just loose dusty soil, and they dont load the sled up either, they make it so these tractors can pull it stock.

About midas, is it a specific tip for and h or is it just a tip? Will it mess up the backpressure and not have such a vacumm thats needed? And can i get one with a 45 degree bend at the end?

The tips from midas are not for tractors, but you just tell them what diameter your manifold pipe is. No, they did not have 45 degree angles from what I saw. Backpressure? Come on...were talking about our H Farmalls.

Alright my next question is how hard is installing a tachometer, if i get the right thing will it be easy? I dont know if its necesary but it sire adds a nice touch and almost everyone had a tachometer so i guess there could be some good function for it.

Your gonna rebuild this H pull it a couple of times and then the pullin fever will really set in. Then your gonna go to a big pull and watch how the H's and M's that are stroked pull fast and rarely run out of power and your gonna just have to have one of them. Then you gonna look at the H you have, that you put all of your free time into, rebuilding the motor fixing all of the oil leaks, probably putting a nice new paint job on it and your gonna wish it was a Stroker. The moral of the story is "There is no replacement for Displacement" Send the engine kit back and get a stroker motor. You will have more fun kicken the crap out of M's and G's with your H than a box of rubbers. A rebuilt stock H is not much good for pulling unless you strip it down to 3500 lbs and pull all of the light classes and you will still be running out of power. They just don't have the torque you need. Now if you stroke it an inch that would be fun!!
