Good All-Around Machine
Model Year: 1976
I bought my 580B in 1992 for about $5k total investment. I've put about 1k hours on it doing everything from digging foundations to planting trees, and it's been extremely reliable. I got a chance to use a late model Cat 426 several years ago, and while the Cat certainly has a nice, quiet cab, I thought my 580 had just as much digging power. It's a good solid machine.
Pros: Digging power, reliability.
Cons: Noisy cab, no AC.
