I'm debating buying a 1.7 ton machine to dig out paver patio. I usually put down 6 inches of base so we are digging out around 8 inches for most of our patios. Are they worth the money or am I just better off digging by hand? I usually have a crew of 4 to 5. I already have a s70, cormidi dumper and a KC70 dumper so I was thinking this would fit in nicely.
