Buy or hire the D6K2 if...
A medium dozer for site grading, cut-and-fill and light earthmoving where a full-size dozer would be overkill. It is hired by groundworks and landscaping contractors needing precise grading as much as raw pushing power.

Buy or hire the ZX350LC-6 if...
Sized for bulk earthmoving, quarry and large groundworks contractors who need high dig depth and bucket capacity rather than tight site manoeuvrability. It sits above the typical hire-fleet mid-range and suits larger civils and demolition packages.
