    4840 vs 5488

    The only proof I have heard is from an actual warranty rep that worked for ih in the 70s and 80s. 1973 came around and Deere out rated IH in the 66 series. He said that ih up the rpm to rerate their hp numbers. He also said everything coming out of the factory was supposed to be shipped 10% over rated hp. This was to ensure that none of the tractors coming up would be a poor runner. I have dynoed a lot of unopened pump tractors. 1456 was 135hp 1466 was 147hp. 1206 was 120hp and a 1206 wheatlands was 112. Makes me think that they set them about right where they were supposed to be.

    4840 vs 5488

    I was reading about Bud Yule and when he was introducing the 2+2 he said they were doing demo's against 4840s. He said everyone that Deere was selling was coming out from the factory at 200hp. If IH knew they were running them at that from factory didn't they push 5488s to 200 or 210 to keep ahead of them ? I think a 54 would clean house vs a 4840. Or 4850 for that matter.
  4. Was talking to the dealer the other day and he said that the new HD will only come in a regular cab with out a box. Says the flatbed market is bigger and Chevy will discontinue shipping them out with a box. What the heck.....I wanted to order a 3/4 duramax regular cab for our auction topper....guess that won't happen anymore. He said I could get a 1/2 ton work truck yet...but they took away all the options on those as well. Can't even get a LT in them going forward. I guess no one is ordering enough regular cabs to keep them interested. Funny thing is all the local coops still buy them 100-200 a time. Wonder if they'll just go to ford.
  5. Gregory area. Not that far west river really. Do u have some 14s by sturgis ?
  6. Hey guys I spotted this tractor 10 years ago while out looking at land we would later auction. This tractor has 3,910 original hours on it. The book has the date when it was purchased and where. Anyway it was ordered without a pto which kind of made sense in west river South Dakota at the time. Anyway here is some pics. I literally gave it a 2 minute wax job on one hood. Crazy story is the owner remembers exactly the last time he used it. September 11th 2001....seeding oats when he heard the twin towers were hit. Always shedded and started every year. Doesn't even have hood wear from the cab.

    986 turbo install

    2- 3688s that I know of (mine included) dynoed 180 after the turbo install. The NA engine responds extremely well to a turbo.
  8. I know most may not agree with me but here is something I have noticed. Ih 90-120 hp models seem to have the most longevity. Specifically non turbo models. 806-3488 size tractors seem to be able to achieve higher hours than the larger turbo sized models. The pto seems to hold up great, the NA engines seems to run 7-10k hours without cavitation problems. I have seen high houred 400 series engines in 966, 986, 3688, and all the hydro models have very little wear when they get tore down. The 361/407 models seem to exceed the 400 series for longevity as well. I know maintenance is key but this is just a observation that seems to hold true.
  9. 20 is the recommended setting so you should be good.

    The magnum 2+2

    The one he drove was not the mfd that Danny restored. It was a legit 2+2 with magnum cab and powershift. It was scraped after the demo.
  11. I purchased the last 3688 built this week. The salesman has been around ih/case since 1973. He told me he drove the magnum powershift 2+2 in 1984. Their dealership had to promise they would demo it out in a field far away from sight. He said it was really crude and had a lot of valves in the cab. Anyway it was built and he said he drove it. It was not finished nicely at that point. Can anyone else confirm this?

    Last 3688 built

    Do any of you guys know if number 501 is even around anymore? Do any of you do trucking ? Needs to go from Indiana to SE South Dakota.
  13. Hey guys. I was studying serial numbers and discovered that this might be the last one built. Number 501 was first and they made 2,572 of them. Added together you get 3073 as the last one built. I bought the tractor after discovering it was the last one made. I talked to the owner and he also confirmed that it was the last one to roll out the doors of farmall. Anyway here is the picture. Hope you enjoy.
  14. The 36 was rated 113.7 pto horsepower and the 4240 110. The 466 is a bigger engine but probably won't lug as good as the 436. The two are a very close match. The 986 was only 105pto
  15. Friendly comparison of which one is better. Sold a lot of 4240s the last few years but never ran one. Any of u have real world experience between the two? 436 vs 466 non turbo.
