this is the Cat 245D ME. this first machine i ever oprated and trained on years ago. it has 325hp, a 3 to 4 to 5 yard bucket, wieghs 129k to 140k depending on model. the the motor was a 3406. i say the 200 serice machines were the best ever and set the way for cat in th 70s to mid 90s.  the are still good brutes and can keep up w the new machines very well. im my personal appion i rather have the old girls or iron then new excavators.
