Buy or hire the E17z if...
The 1.5 tonne class is the busiest size in UK hire fleets. At 1,712kg it goes on a braked plant trailer behind a large 4x4 or pickup, and digs to 2230mm 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.
