Buy or hire the D6K2 if...

  • you want one that is the bigger machine by 26,668kg

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 U27-4 if...

The step up from the KX019-4 when you need more depth and reach but still have to work close to walls and fences. Tight tail swing is what makes it usable in an occupied garden, and it is one of the most common hire machines in Britain for exactly that reason.
