Buy or hire the E55z if...
A midi excavator for groundworks, utilities and landscaping contractors. At 5.3 tonnes it arrives on a lorry rather than behind a car. It digs to 3434mm. Zero tail swing means the back of the machine stays inside the tracks when it slews, so it can work tight against a wall or in one lane of a road.

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.
