If you have got a big bush, then chances are you have to put in quite a bit of effort to get it trimmed on a regular basis.
If you have got a particularly high one, then you will probably need some specialist company to come in so that they can get to the top of your bush before strimming it back.
But one such company decided to throw health & safety to the wind by rigging a tractor-mower to a crane before hoisting the vehicle to the top of the enormous bush.
You can imagine how the bush would have looked after it had been hacked to pieces by the unsteady tractor-mower.
Probably best to leave this sort of thing to the professionals.
