im just curious everyones opinion on which manufacture makes the best excavator. not mini excavator 20 ton and larger??? and why they think they are the best.....

The Cat's (I assume you mean 320C and not B) has a maximum swing torque of 45,611 ft-lb (from Cat's website, machines, hydraulic excavators, 320C L) whereas Deere's 200C is listed as 41,250 ft-lb. The Hitachi Zaxis is listed as 43,218 ft-lb. The only way Hitachi can arrange for the Cat not to swing up the load is if
a) the Cat's swing radius was greater than the other machines (either arm/stick extended further or longer arm stick combo);
b) the Cat's bucket was bigger than the others
c) Cat's idle speed has a dramatically lower swing torque than the other machines
d) "Idle speed" is flexible in its meaning (exact RPM or equal horsepower?)
I didn't see how the equipment was set up, but something sounds fishy.
I know this is a discussion thread, and certainly have no right to comment on others' choices of "best excavator."
