To summarize D Slater's explanation:

The hood is longer because the TA makes the tractor longer.

Nat, I never explained good enough or you missed my point. The T/A has nothing to do with hood length other than the name of MTA hood. On the M SM MTA where the gas tank mounts behind engine that distance behind engine remains the same for these tractors. Since the grill mounts to radiator and on MTA the radiator is mounted farther forward than M or SM gas tractors because of front bolster change the hood is longer to span this differance from grill to tank.Also the steering worm shaft is longer on MTA than M SM gas tractors. Rear worm shaft bearing(not realy a bearing) was different on MTA because longer shaft changes angle and height just a very little there. Finaly if you were to bolt a MTA type front bolster on a M tractor a MTA hood would fit the M. Know one person who has done a trick like that. He used a MD bolster so it would look the same as M, and a SMTA gas hood Just so he could increase the distance between engine and radiator and not trim fan shrould for char lynn pump clearance. That reminds me MTA shrould is different than M SM.

Different shroud?

I believe you (there is no point in doubting D Slater) but I just had the radiator off one of my SMTAs. The shroud had been butchered by a previous owner near the generator pulley. I had a spare shroud in the barn and replaced it. I bought the shroud a number of years ago with this swap in mind. It probably came from a M based on the salvage yard where I bought it. It looks the same and fits perfectly.

You can interchange them, but to be correct the MTA gas is little deeper because more space between engine and radiator,few other little differances also. Theres a little differance even between MTA ones. 2 types I have noticed the differance is at or near the shuter control linkage slot,but I can't remember now exactly what the differance is. Also I'm human and going to make a mistake any time.

Answered this not long ago but will try to explain. The distance from where the 4 frame rail bolts on each side go in the bolster was moved rearward in the bolster itselve which made the distance the same as MD SMD. tractors. On the MTA 400 450 they made bolsters the same for gas and diesel. Someone in IH probably wanted to know why they needed to make both size bolsters for M SM and MD SMD. To make this more clear when a SMTA bolster is bolted to frame rails (which are same length on M SM MTA) It moves the vertical steering shaft and radiator mounting forward around 1 1/2 inches or close. To make up distance on the longer tourqe tube space was left between gas tank and steering post. If you look at SM and SMTA live hydraulic reserviors you will find 2 sets of mounting holes for rear gas tank support. Front set for MTA rear for SM. One other thing on gas tractors if a fellow does a good job of shortening frame rails and making new holes to put a MTA to 450 type front bolster on that makes radiator the same distance as a M gas. then use lower coolant pipe and steering worm shaft from M. M hood will fit MTA just like it does on a M and most people will never notice. No I have never sold one like that.

I think it is because the torque tube is longer and to retain the gas tank location, it needed to be a bit longer. JimN

However, it is an odd coincidence that the SMD and SMTA have the same hood length. That may have been the reason why it is 49 and 1/8" (I think, without checking) and not some other random lenght near that measurement. This meant the factory was able to use existing tooling. The bean counters were at work.

Wardner Just my opinion how the lengths came about. The M was in production before MD came along. Well the MD engine is longer than gas and things got tight in front of engine so they made bolster on MD sit farther forward. A MD worm shaft is same length as MTA one also. After to many years I think someone at IH figured why not standardize bolsters. So on MTA through 450 they did. They took a MD size bolster and squared the corners and added holes. Same was done on clutch housings on M MD SM SMD. The diesels used a different one than gas until stage 2 SM, then they were same after that, of coarse that was getting toward end of production.

I owned a 48 MD single fromt wheel bad rubber on rear, good tin fine running tractor (sold for 1900 w/class II 3pt) I did not measure its hood to compare, your point is well taken. If the MD series were "M" length, and the SMD was SMTA length the planners may have been working some years in advance. I wish they had kept at it instead of model proliferation and quality issues that later wounded the spirit and split the heart of IH. JimN
