Large gardens with extensive borders and areas where grass can become quite long at times e.g. orchards will require the regular use of a petrol line trimmer. As a rule, these machines are normally fitted with engines of approximately 25cc in capacity, plenty enough power for the longest grass conditions any domestic garden is likely to contain. You’ll notice that all petrol line trimmers are equipped with a loop-handle midway down the shaft, offering far better control over the trimmer head than the wider grip bars of more powerful machines; essential when trimming around precious plants and ornaments.
