re: .

I bought a Ryobi multi-attachment tool. The trimmer head comes with it., and I got the pole-saw attachment as well. It is a 4-stroke so you don't have to worry about mixing. Just check the oil levels every few uses. So far (2 years), it has run great with no problems, and the maintenance is very easy. For the record, I know nothing about working on anything mechanical, and I fixed all of the small problems I had just by following the instruction manual.
