Seat On H farmall tractor

We have an 1940 H tractor which I thought was pretty original. My grandpa got it in the late 1950's so don't know any previous history but we always thought it was basically old-new stock. A friend pointed
out that he didn't think the seat was original to the tractor. I have seen other seats on Hs but assumed this was a real deal. Can anyone shed some light on what seat this actually is and it it right for
the tractor?? The pan seat had a cushion on it for a long time until the mice finished it-No holes in the pan seat. The mount looks like it fit the platform fine and not modified? Just has me wondering now???

I do not know if its original to the tractor, but that seat assembly is definitely IH (or IH sourced). Exact same unit on my 125 SP combine, which was built during the same era, if thats any help

yes, that is an original early h seat

IIRC, the platform on 39 and till mid 40 Farmall H tractors had a deep groove in the rear portion allowing a square tube seat support to travel into it. Look to the part and date numbers cast into those components. So production date mid to late 40 would have that seat. Jim

Many hours on an SP125. Greasing it on every fitting is a very dirty task. Many stories. Jim

Thats original to an H. Same seat was used on its big brother M. Not sure if it was used on other models.
However, it looks like its mounted to far forward. It appears to have only one bolt per side at the platform. It has multiple holes to adjust it front to back. It should have 2 mounting bolts per side. I don't think it was intended by manufacturer to be mounted that far forward using only one bolt per side.
This style seat, though original, had a problem with the spring breaking. Once the spring broke, the pipe would settle downward as far as it was allowed to travel, and there wouldn't be any spring to it anymore. Not un-common to see these original seats today with broken springs that were never replaced.
There was a delux seat you could get which is basically whole different seat assembly. It had a spring directly under the seat, and a shock absorber. These actually might be more common to see today than your original seat. Not sure if the delux seat was available from factory, or only as aftermarket. That was before my day. But wouldn't be suprized if they were available for extra money as an option when new. I don't know that. Just going by how common it is to see the delux seat.

the seat is as original as those rear tires.

Did you really! Love to hear some war stories! Mine isnt operational; I bought a wreck and drug it home with the idea of rebuilding it. Good thing we took 2 trucks as we had to stop about 5 times between Salem on 57N and 70E to pick up the pieces that fell off. Good thing that trip wasnt any longer or the entire combine would have ended up on the second truck.

This tractor is Serial # 24901 which I guessed would be April 1940. It does not have a channel in the platform so is later than that. The starter rod/pedal goes through the steering wheel pipe pedisatal near the bottom so that is rare and hardly ever see that on a H Cledddy

That is interesting and thanks for that information. I think my Grandpa got the tractor in 1958 for basically the price of parts to put it back in good operating conditions($500.00 aprox) He liked his c best and was basically retired so Tractor seen little use until he passed in 1974 and little use since my Dad passed in 1994 and not much use since then. I would replace the tires if it didn't cost so much but these still hold air??Cleddy

That good to know and thanks for the information. I will check that mounting out? Being tall it should be moved back. The spring is fine yet Since my Grandpa used his C most and he was pretty big this spring was spared but the C seat spring was crushed to a permanent flat position. I never gave it a thought until seeing a c with a good spring?Cleddy

That seat was used starting at serial number 15698. Early transmission covers only had two bolts for mounting seat base. Had a 41 on farm when young that only had the two mounting holes. Also the rod through steering post to engage starter switch. Think I remember the 2 hole top cover making it into 42 on some and into 43 some or at least one I remember, but it was cast earlier before going on a tractor. Next design called the hydraulic seat made it hard to operate the rod in steering post. Early hydraulic seat attachments came with a foot lever to operate starter switch in rear fuel tank support.

Looks like the seat that was on great grandpa's 41 H. I sure wish grandpa would have kept it!

My bet is that the seat is mounted for short people, namely children, so they could reach the pedals.

It was common in that day and age to put the kids in the tractor seats as soon as they could hold the steering wheel. Lots of guys here have told stories.

That is the exact seat that came on my Dad's 1943 H that he bought new in '43. The '43 my Dad had ,did have the larger 1 3/8 PTO and not the 1 1/8.

I have a seat like that, but not on a tractor.

We had one on a 42 with that starter rod. flat spoke cutoff wheels. Jim

Ahh, looks like original rims and tires, and seat!!

I think D Slater is right about the 2 holes/bolts. I looked at my 40 parts tractor, it has 4 holes, but impossible to use more than 2 bolts in the
seat assembly. The rear two holes must of been for adjusting the seat even further back, not using the front ones if that was the case. Just guessing.

My 43 has the 4 holes closer together ti use 4 bolts for mounting the seat to platform. Also coinciding with the change Slater talks about. I didn't realize this tell I looked at my 40 H parts tractor.
