The selection of the best hedge trimmers depends on the size of the hedges you have to trim. An area which has many thick hedges will most probably require a gas operated hedge trimmer. It has many advantages and the foremost is manoeuvrability. Since the power is inside the hedge trimmer there is no need to be handicapped by a long cable or a dying battery. The petrol engine is a bit noisy like a moped but it has tremendous power for cutting thick and long hedges. The only drawback is that these hedge trimmers are a bit heavy and can be categorised as perfect for professional gardeners. The best hedge trimmers powered by gas are The Stihl HS 45 and the Echo HC 150. The Stihl hedge trimmer has the choice of an 18” or 24’ double sided blade. This is as powerful as it gets. The Echo two has a double sided blade and this is in twenty inch size.
If the work involving the hedges in your garden is of a medium level then the electric hedge trimmers are perfect for such a job. The choice of blades also matters in the electric version of the hedge trimmer. Double sided blades are always better because they make shaping of the hedge easier. One can give a curving edge to the hedge or a sharp right angled edge. Double edged blades make it easier to get the desired shape of the hedge. There are many different varieties of blades and they range from the plastic to the very strong and sharp steel blades. The gap between the blades also matters, the closer the blades are to each other the more powerful will be the cutting. The best electric hedge trimmers are the Black & Decker HH 2450 or the Craftsman 79442. These are definitely better than the cordless variety because the speed does not tend to vary as the battery discharges in the cordless hedge trimmer.
The third choice in hedge trimmers is the battery powered variety. This is perfect for areas where the hedges are not too many. The battery life is rather limited to half an hour or a little more so all work has to be stopped after that period of time. The advantage of the battery powered hedge trimmer is that it is lightweight and easy to carry. The solution to the limited life lies in buying an extra battery and just changing the battery when the first one gives up the ghost. The best hedge trimmers in this category are the Black & Decker NHT 518 which has a twenty two inch blade. It runs on an eighteen volt nickel cadmium battery and has a running time of fifty minutes. It weighs only 6.4 lbs. The other good hedge trimmer is the American Gardener RH18.
A final factor in deciding which is the best hedge trimmer lies in the person who is going to use the powerful tool. An experienced and powerful male will go for the gas variety because of the extreme power it generates. An occasional and hobby gardener who is not so tall and hefty will definitely prefer the lighter battery operated models.
