- you want one that is the bigger machine by 24,418kg
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 6ST-2S5 Swivel if...
Suits groundworkers who need to tip to the side or rear without turning the whole machine, useful in trenches or narrow access where reversing to line up a straight-tip skip is awkward. The 6 tonne capacity sits in the middle of JCB's swivel dumper range.
