"I've been doing this for more than 25 years now, so I know what I need from my machines,"
They've seen their fair share of sunsets but don't dismiss Barry Pogson and his PC60 as being too old for the job.
At 70 years of age, Mr Pogson is still the first choice in the Melbourne area for coring work (cutting hollow tubes in solid rock) and Barry's first choice is his trusty PC60.
"I've been doing this for more than 25 years now, so I know what I need from my machines," he said.
Mr Pogson said the tough bedrock he cuts through with his core barrel attachment could overwhelm some machines, but not his PC60.
"It's got a scary amount of torque running through the core barrel," he said.
"It's enough to keep the barrel turning and cutting through basalt and weathered granite, even with the weight of the excavator on top of it."
Mr Pogson estimates his PC60 is more than 20 years old, but its length of service and more than 8000 operational hours haven't diminished its effectiveness.
"They always were, and still remain, an underrated machine," he said.
"They'll hack it with the big fellas every day of the week, but they're still small enough to get into places others can't.
"And they just last and last they're a lot more robust than many of the other machines you see around."
Mr Pogson said he has no plans to retire any time soon, and that goes for his PC60 too.
"I love what I do and make good money doing it, so I think I'll keep it up," he said.
"I'm very happy with the PC60 and I'm definitely not looking to replace it any time soon.
"It's still doing what the new machines do it's just as reliable and capable.
"They're quite special, really why would I ever give that up?"
