I believe the first is a Cat with the british hydraulic set up but which size? the second has a different method of raising the blade - what is it?

Noel, I've been waiting in the wings hoping someone would answer your questions so I wouldn't have to expose my utter lack of knowledge on the subject. I'll present what little I know about bulldozers in the hope someone will exclaim, "What's that berk goin' on about now!" and set us both right. I know of three main manufacturers of large bulldozers for the Allies, Caterpillar, International Harvester, and Allis Chalmers. There were other manufacturers of heavy equipment and tractors such as Case, Clark, Barber Ellis, Le Tourneau, and I think JCB to mention a few but as far as I know they didn't make bulldozers other than the dimunitive CA-1. (Jump in anytime guys.) Each type had what a Detroit auto manufacturer would call "design elements", i.e. the Cat D4 and D7 had a flat radiator grill perforated with round holes while the Allis Chalmers had a curved grill with horizontal slats. One should take the time to peruse various pictures of the different bulldozers and you'll start to see some subtle and not so subtle differences. As for raising the blade, I've seen two methods; hydraulic and winch but I couldn't tell you with any definitiveness which manufacturer used what. This is barely a primer on the subject and as I said, hopefully someone else will post further info. CHIMO! Derek.

According to TM 9-2800 (1 September 1943) War Department tractor / bulldozers were standardized under three general nomenclature groupings, with several commercially available models in each group, as follows:
Tractor, Light Caterpillar Tractor Co. Model D4 (G-151) International Harvester Model TD9 (G-99) Tractor, Medium, M1 Allis-Chalmers Co. Model HD7W (G-125) Caterpillar Tractor Co. Model D6 (G-69) Cleveland Tractor Co. International Harvester Co. Model TD14 (G-132) Tractor, Heavy, M1 Allis-Chalmers Co. Model HD10W (G-98) Caterpillar Tractor Co. Model D7 (G-126) International Harvester Co. Model TD18 (G-101) While other tractors were procured during WW II, those listed were the most common. CHIMO! Derek.

Bulldozer Question
(1)The cats I saw were D4's and TD9's
(2)HD10's ,TD18's , and D7's (3) D8's . The D2's were too small to do much . Hd 10's were good for dirt work . TD18's . were called ,tighten 18 nuts and bolts .There swing frames were always comming loose . I didn't see alot of D7's ,The D8's were the work horses .Most of them had the Le Tournal dozers on them .Thats the ones with the overhead cable to lift the dozer . It could lift about 2 ft higher then any other dozer whitch was great for pushing over trees .Alot of soldiers got killed on them as they didn't have a canopy .George
