Odd looking dozers

I haven't seen dozers like these before.
One is a D21 Truck Tractor with attchements,
and the other only has a push block bumper and no blade

the first is a push cat and the second has some options for the DW series tractors

That D9 is a ripper Cat we would take 2 of those in a field to rip for oarchards with long 6 ft single shank and if the going got tuff one would get behind the one with shank sunk in all the way and push against the ripper. Now they just go in with one D10 hightrack and rip that deep without a problem

W- so one D10 high track will produce more pull than two D9's?

Hi, Mike Mc.
Dunno. Never seen the two side by side doing the same job. And I'd bet that a D10N or D10R would have a hard time matching a DD9. How-wevver, the 76X and 84W D10s were 700 hp and 91 tons. That is 70 hp less than a DD9G but about 6 - 7 tons heavier. It would be interesting to see them side by side.

To me it is not as important about how much horsepower a machine has
as long as it it able to spin the tracks with a full load in front.

Weight and traction is what gets the job done.

The total weight of two D9's along with the traction of two sets
of new tracks would push a lot of what ever is in the way.

We are back to the old horsepower versus traction argument, I've seen D10's working as well as doubled and tripled D9G push tractors, I reckon the D10 would have much more 'bite' and one thing is sure, the cost per ton produced would be much less with the D10 than a DD9G.
