Hey Guys, Looked at what was advertised as a 53 Super H, But didn't look at as close as I should have, now wondering if it just had the Super H decal, had him send me the serial # 4137DJ, not sure if this is the complete #. As I said in an earlier post, it does have the disc brakes, & thought that was one of the tell tale signs of being a Super, had the multi valve hydraulics & the shorter oil filter canister also. What's the DJ on the serial # indicate also ? Might have to have him check the block # behind the oil filter to make sure. Just what to make sure it's indeed a Super H ! Thanks for all & any responses. AL

Serial number prefix for an H will be FBH. Serial number prefix for a Super H will be SH. Disc brakes are not an indicator as the last few '53 Hs also had disc brakes, and before that the Ausco-Lambert aftermarket disc brakes were available for the Hs. The shorter oil filter canister showed up somewhere around 1946 or 1947, so that is not an indicator either.
 
DJ is a suffix for a Super serial number, so I think it may be one. One of those letters means Rockford clutch, I think the other may be high altitude. H serial numbers either had no letters after them or were x1, x2 etc., at least in my experience.

As Rusty says,the only way to know for sure,is to look at the sn. SH4137,means your tractor is an early '53.My SH has a 2xxx sn,so its even older.There are few subtle differences,but most people are not familiar enough with them to know
 
Zack,I believe the 'D' is 5000ft altitude pistons,the 'J' is rockford clutch.Al,is your tractor in Colorado,or another "hi altitude"location?
 
DeltaRed, It's in up state NY, flew up in my plane to look at it on Sunday, but i would not concider up state NY high altitude, if I remember correctly, the airport elevation I flew into was something like 1050ft, so not high altitude. Kinda kicking my self for not looking as close as I should have at all things on the tractor, gave him a small deposit on it, as I what to sell my 41H as I need to make room for the 53. Thanks, AL
 
(quoted from post at 07:10:34 06/12/12) Rusty, not disputing your info., but Dad bought a new H in 44 and it had the short oil filter.

No problem. I just mentioned '46 or '47 because those were the earliest years I could personally verify. I've also got a '41 I-4 project tractor that has the short filter, but I'm pretty sure it is not original.
 
Al - I found my "high altitude" SH (s/n 16xxx DJ) in the northern Finger Lakes region of NY. Elevation there is 1,100 ft or so.

Gotta think it spent its working career around the Finger Lakes. Unfortunately I have no idea where it was shipped originally from the factory. Seems unlikely however it was delivered to a high altitude destination - there's no 5,000+ ft farmland within a good 1,000 miles of here!
 
I had a SH parts tractor out of eastern Cayuga county that had the DJ designation. It had firecrater pistons, which I think were part of the high altitude package. I thought they were designed for use in the West at higher elevations than here, but I suppose they might have been bought that way for the sake of higher compression and thus more power.
Zach
 
Zackary fire crater pistons wern't made when the SH was. Agree thats a SH serial number and not a H.
 
Thanks for the correction on the firecraters. What differences were there between a high altitude engine and a regular one? Did they use step head pistons at that time?
Zach
 
Zach - I've spotted several other "D" spec SH's here (western NY) over the years. So they are not that unusual.

And yes, the higher compression WILL give a bit more power at low elevations over a standard (low altitude) engine. So it would make sense for low elevation buyers to spec the 5,000 ft engine. But it would probably require rigorous side by side dyno testing to discern the difference.
 
Rusty; I know you have probably seen in past about oil filter canister sizes. We had a new 1942 H made in about april . 1942. It had the long filter on it. Some where around that time IH put a short filter on and then went back to long one for a while, mayby a mo. Then went back to the short filter some time after May or so in 1942. I think this is right. Been a long time ago. Buck
 
Our '53 Stage 1 came off a farm near Toronto Canada (It's in So. Tier of NY with us now) where it was bought new and spent life as a loader tractor...it's a DJ serial number.
Older Gentleman I know used to work for IH dealer in Cortland in the '50s said that when the Super Cs came out they almost never sold Hs because the Super C would do "just about anything an H would do for less money, and usually do it handier." (his words not mine, but I fully agree). He said they just quit ordering Hs. So when the Super H came out, they wanted to show as much difference between the H and the Super H as they could in order to justify a guy moving up from a Super C, said they always orderd D code High Altitude SHs. He said any dealer anywhere could order them, not just guys up in the Mountains.
 
Hey Al, its jim down in md. There is a 54 sh stage 2 for sale its all complete good rubber ect perfect metal but is stuck from setting. I think he was asking 1500 but could probably get it alot cheaper. Jim.
