Good question, the number referred to the weight rating in tons.... I don't believe it had anything to do with hydraulic or dozer though, as the "HD" designation was used on all crawlers regardless of use (bare farm, cable and hydraulic dozers, etc)...

That one sure looks nice. I saw ad for a TL loader on the back of a grader. Looked awkward to use.
Sorry, meant to say it is a tracked unit. Similar looking bucket (very worn), with a cage and is equipped with a reverser. Standard 3 bar loader grousers. (I'm not sure he even has it anymore, it was pretty beat 5 years ago and he let it freeze about 3 or 4 years back.) Was hoping to find pictures etc to help identify it.

Hydralic Dozer is correct. By the time the HD5s came along they didnt change the designation. The hydralic refers to the blade lift system not the transmission. This stuff was done in the 30s and 40s when they didnt use many ag tractors, they continued the lettering system in the later machines, not like today when ya gotta have a program to keep up on model numbers!!!

Hi guys, new here.
For IH, "T" stands for TracTractor. "TD" is the diesel version of same. Gas types were the norm so no special designation other than a mark on the serial plate to denote distillate etc.
An AC question. My nephew has (maybe had by now) a small AC loader, with what looks like a WD engine as a power plant complete with hood and gas tank. Any idea on the model?

I have been around HD Allis tractors my whole life and have never had positive answer to what the H was for.Always assumed the D was for diesel as with the Cat's and IH crawler tractors.In the 1930's when Cat changed there numbering system they had R2,R4,and R5 gas tractors as well as the D diesel models. Early IH crawlers were called Tracktractor 35( or what ever no. model) and the Tracktractor D35 ,the diesel model,witch I beleive was shortened to T or TD as they also had gas as well as the diesel models.

Mmm, the HD5 came as a tractor only and the blade, bucket or other attachments were built by outside contractors to fit the machine. All were straight gear machines without torque converters,

HD = Hydraulic Dozer ? Other post is right, after Fiat go in, FD was Fiat Dozer, FL was Fiat Loader, FG was Fiat grader.. Dont think the construction division had the same designation setup as the Farm group.

I believe the H later came to stand for Hydromatic drive, the torque converter. There is something about this in Swinford's book and "The plow Peddler" mentions that Allis allowed the automotive industry to use the Hydromatic term under their copyright.

I'm guessing as when Fiat took over Allis industrial and changed the model numbers to TL, hence, track loader. Maybe IH was the same. The H I'm guessing again was an abritary series distintion. The next reasonable letter code that wasn't used after the D series. Anybody remember the Polaroid SX70 cameras? That model number was pulled out of a hat.
