I got this ts420 from an estate sale completely disassembled for basicly nothing. I had to put in a new piston bearings and seals filter and belt. Put it all back together runs great so i ordered a muffler. I dont have a concrete blade or a need for it but i might use it on metal for cutting up scrap and stuff. Got about 120. in it now if i dont use it this summer ill sell it in the fall.
