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 EZ17 if...
The 1.5 tonne class is the busiest size in UK hire fleets. At 1,724kg it goes on a braked plant trailer behind a large 4x4 or pickup, and digs to 2,590 mm for footings, drainage runs and fence posts. 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.
