Hedge Trimmers

I am from Sri lanka. I have several hectares of rubber field which needs frequent under growth clearing. As the terrain is hilly and rocky you can not Drive a lawn mover like unit to clean it. Can I used a hedge trimmer like HUSQVARNA 327HE3x to do that job? The maximum diameter of a branch may be 20-23 mm. If I am correct a operator standing can trim the bushes about 1 m height with a angled cutter.

Also I have not seen these units any where in sri Lanka. Is there any specific place where I can by it in Sri Lanka.

If not available in Sri Lanka is there any dealer for this specific unit in Israel where I work right now to purchased and take home?
