Komatsu d39 vs cat d3! 

2 different size machines! The new Cat D1 is the old D3… also the Komatsu should be a PX which is the wider pad 39 size … typical Cat comparison here LOL

Im pretty sure I rented that same P39 from Leppo this past summer. I really liked it. First time I ever ran a Komatsu Dozer. I think those new D3's might have it beat though

Also put same size track on the Komatsu

Which has more draw bar pull

Both nice machines but I got to go with the king of dozers caterpillar

Cat has more track on the ground

Komatsu 51 vs that new Cat D3 that's what i want to see

2 different size dozers … the equal now is the D1 Cat vs. a D39 PX NOT AN EX that’s 2 different width of pads you’re comparing … typical Cat comparison LOL the Cat fan boys would buy Cat gold plated turds of they could 🙄😎

The cat is just idling the kumatsu is winding out.

New D3 is old D5k2

That d3 tho 💪👊🏾

Komatsu d39ex is different from d39px . The px is stronger than ex .

I think the Cat wins this one.

Both are amazing but CAT always win ❤️
