Brief the supplier properly
Size to the material and cycle
State the material, estimated volume in cubic metres and where spoil goes. Loading trucks, side-casting and double-handling each point to a different machine size and bucket.
Measure the access, not just the gate
Check gate width, side passage, overhead lines, tail swing clearance and whether a zero-swing machine is needed next to a boundary or live traffic.
Pick attachments up front
Ask for a tilt batter bucket, trenching bucket, auger drive, rock breaker or grab as part of the quote. Adding one on day two usually means another float movement.
Match undercarriage to ground
Rubber tracks protect paving and driveways; steel tracks and wider pads suit soft or abrasive ground. Wet clay can stop a wheeled machine completely.
For Coffs Harbour specifically, tell the supplier the exact site address so they can confirm the depot the machine will come from, the travel or float charge and any NSW permit needs.
