Hi, I need to excavate a ~250 metre long tench at a depth of 0.6 metres in a relatively open area of woodland to accommodate a 70 sq.mm, 6942X mains electricity cable. Would a Pedestrian Trencher be up to the job? It will certainly hit tree roots in the heavy clay soil. Space is too restricted to use an excavator and a mini digger would, I would say, struggle to rip through the roots plus the site slopes quite steeply in places causing stability problems. I would prefer a pedestrian trencher as it digs a narrow trench (100 mm) and deposits dug out material at the sides of the trench which makes for easier back filling.
TIA
