    Hedge trimmers

    Hedges around your home can grow at an astounding rate. They seem to grow more quickly when you have the least amount of time to devote to them. Whether it’s the only weekend you have had off from work in months, or if you are retired and attempting to keep manual labour to a minimum, cutting your hedges by hand is no fun.

    Depending on the amount of hedging around your home, it's advisable to invest in a power hedge trimmer to make this chore less time consuming. The best advantage will be the way your hedges look once you get past the slight learning curve of the handy power tool. Less manual labour means you can devote more of your focus to the way the hedge looks, rather than how sore your hands or shoulders are from using manual tools.

    Advice when choosing hedge trimmer blade length

    In most cases; the longer the trimming blade is, the faster you will be done with your tedious task. Selecting the blade length depends on the size of the bush and the number of hedges on your property.

    Here are a few rules that will help when choosing the blade length of a hedge trimmer:

    • Small hedges only require a blade length of 46cm or less.
    • Small to Medium hedges can accommodate blades between 47-56cm.
    • For quick results, a medium to large sized hedges will require a blade of 57cm or longer.

    These are only guidelines; you may feel more comfortable with one particular blade length.

    Advice when choosing hedge trimmer blade width

    A measure of the blade's width will give you an idea of the maximum diameter range that the trimmer can make a quality cut with. For example: A 20mm wide blade will easily handle a 20mm diameter branch thickness with ease.

    If you are considering a smaller width to save money; consider the consequences of getting a powered trimmer stuck in a knotty branch and having the trimmer kick back on you. That extra width ensures the hedge trimmer blade is less likely to get stuck in the branch if you hit an obstruction. No doubt some poor bloke had to learn this lesson the hard way.


    Hedge trimmers can be powered in one of three ways:

    1. Mains electricity
    2. Rechargeable battery
