- you want one that has 18kW more power
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.
