(8200 kg) So, 84-87K without the counterweight depending on the bits hanging off it. Basically a hitachi with a deere 6125 engine. I've been told the deere engine puts out a bit more power under heavy load and drinks a bit more fuel in return. I've never gotten any numbers, but i get the impression that it's not a huge difference on either count.
I love the 450clc. Just wish it had the d series cab. Its a good all-around hoe. Like 1ton said its got a 6125h. Big engine not really having to work offel hard.
