About 8 days but not been pushing it. Been lifting about 60 tonnes per day (2 artic loads). It tops and lifts the same row, topper in front of Opel wheels. Single row machine. A steady job but low capital and running costs. DB780 tractor unit uses 5 gallons of diesel per day. Biggest expense is the chains which cost about £50 per ha, being the main wearing parts. A set lasts about 5 years. £2000 to replace if new but have been living on ones salvaged from scrap machines so far.
