Dedicated root cutter
Well why not .You hear of dedicated stumpers .Never thought of a rooter but come to think about I have a couple I could relegate for that task .
It was free and really didnt want it. But after tuning etc. Saw runs great for it's size.
Got rid of alot of roots I been wanting to cut out for years. Just never wanted to use one of my other saws. So it worked out.
One 4" root had a dang brick under it

. So takes some time and resharpen more often cutting dirt etc. But no biggie.
Mowing has been so much easier this year do to the early work.
