Buy or hire the D51PX if...
A mid-size dozer built with wider, low ground pressure tracks for soft or wet ground. Groundworks and landfill contractors choose the PX variant over a standard-track D51 where the ground itself would otherwise bog a machine down.

Buy or hire the EZ50 if...
A midi excavator for groundworks, utilities and landscaping contractors. At 4.8 tonnes it arrives on a lorry rather than behind a car. It digs to 3,667 mm. 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.
