suggestions

hello I'm inheriting my great grandpa's property. the home hasn't been touched in years and a portion of the yard has been taken over by a forest of bamboo. The bamboo is at most 3.5 inches in diameter I have an Echo string trimmer with a brush cutter attachment but it goes through blades...

Title pretty much sums it up and I've done the research on HOW to do it. Still probably going to get stuck lol. I was wondering who out of you have handled a ported 346xp, I mean out of the box the engines rpms mac out at 14,500 which is already insane. Curious on your thoughts on the project...
