battle with pine stump

testing a 6" 3tpi blade and a 9" 5tpi blade - on decade old stump sticking up 3 inch off the ground

 

and you can see the 3tpi cuts faster .. . at this point i used the blades on 3 other stumps ,, so both are not new at this point ,, i also dug into the dirt with the blade and it did not break .

 

..

 

also did not want to just continuously use each tool ,, so as to burn them out .. and kept taking a break every 10 minutes or so .. to let it cool off ..

Done
