Not a 3T. Earlier. GWH

It is a D8

I thought too it looked like a D8 possibly a 1H or 8R serial number tractor, more like a 1H guessing.

Thanks for the quick reply,s.

So this is not an D7 3T butt an earlier Cat an D8 and possibly an 1H.
Still learning,I am new at this game of Cat,s,so thank you for the answers.

Greetz!

Any reply,s are much appriciated.

I think its an 8R D8. Given by the water pump. Jeremy

Here you go.....if the picture was taken in 1941 as it states, then this is either a 7M or a 4T maybe. But a very early 3T would look like this.

I think that both the D7 7M and 4T look like the 3T. The first picture looks like a D8 8R or 1H.

1st one appears to be a D8, 1H or 8R ??? It has a LeTourneau dozer kit, blade would be a WCK-8 ( manual angle dozer with manual tilt)


The 2nd one is a D7, most likely a 7M with a LeTourneau front mount power control unit, usually seen as equpped like this one with a Hyster-Willamette 7N towing winch on the back, it too has a WCK-7 dozer blade, manual angle and tilt. 4T production did not start until '44, but they are practically identical for the most part anyway.

From what I have seen, the LeT front A-Frame as LeT calls it, is tilted forward on D8's of that era, whereas the front A-Frames on D7's of the same period were just about perpendicular to the ground, straight up, though they both flex and ride on trunions, there was probably a dimension that required those kits mounted on D8's to tilt forward.

The D7's and D8's were fitted with different aftermarket acessories in those days, most by LeT, others also had LaPlante-Choate dozer kits hydraulic trailbuilder models and ones similar to the cable operated LeT models in the photos, I have a photo somewhere of a depot staged with lines of tractors, you can see a lot of them were fitted differently, WWII era, staged before being shipped to their destination.

There is an Italian website with a lot of WWII photos of these Cat's, would have to look up that link, might be able to post that later.
