When should I hire a 3.5T instead of a 1.7T excavator?

Choose a 3.5T excavator when you need more digging depth (up to 3.8m), more bucket capacity for faster earthmoving, or harder ground conditions. The 3.5T is ideal for larger pool excavations, footing excavation, civil trenching, and site clearing. If access is tight, the 1.7T is the better choice.
