It has sufficient power to do mostly anything you need. It does have a solid drive-shaft so you could, if needed put other gearboxes on it to do more tasks. The head is easy to respool and holds the most line out of any of them out there, redmax also holds alot of line.
True it is a four stroke engine, however you still mix gas and oil. The engine will sound quieter than others but still has the power.
When you run this for a while, coul dbe 50 or 60 hours or so, if you feel it being hard to pull the rope, than you have to adjust the valves. You should opnly have to do this one time, after that, you should be set and not have to worry about that again.
You will want to use a higher quality oil mix, fully synthetic is recommended otherwise it will tend to clog the muffler up.
