Buy or hire the D6K2 if...
- you want one that is the bigger machine by 21,123kg
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 3CX if...
The machine most people picture when they think of a building site, and still the default where one machine has to both dig and load. Groundworkers and utilities contractors buy it precisely to avoid putting two machines on a small site.
