I noticed our street side hedge was encroaching on to the roadside footpath. It was time for a trim.
Last year I bought a Makita EN4950H petrol power pole hedge cutter. It has a relatively quiet 4-stroke petrol engine and is not too heavy. It only took about 30 minutes to trim the 150 metres of hedge up to a height of two metres, and about as long to sweep up all the cuttings.
