String trimmers, also known as strimmers, use a length of monofilament line rotated at high speed to trim grass, weeds and other growth. The JCB BC-26 is a string trimmer powered by a 26cc, .9 horsepower two-stroke petrol engine. It operates at 2,800rpm at idle and 10,000rpm at maximum speed. The BC-26 uses 2.4mm or 2.8mm (15/64 or 9/32 inch) monofilament trimming line and cuts an 45 cm (18 inch) swath. The fuel tank holds 0.25 litres (0.44 pints) of petrol/oil mixture and the BC-26 weighs 4.54 kg (10 lbs).
