Post hole auger

[foxhunter4]

I have used my PD15 Landpride posthole digger on a Kubota B26 to dig about 25 holes with a 9 inch auger.
Question: Do you need to periodically sharpen the auger, and, if so, how often and what is the best way to do so?
Thanks!

Welcome to the forum

Sharpening can't hurt. I'd use a right-angle grinder.
