It's okay, the consensus is with you. Do something else.
So, while I have mowed these same pines with my belly mower, I realize it's a bit different as once I'm over the bend, my blades kind of saw them as I slowly ride forward. As mentioned, I'm tired of dulling blades and have several other areas I need to get on top of before they get too much bigger.
So now I'm probably just going to pop as many as I can with my tooth bar. I've done a lot of this in the past with my old L3800 with bigger trees. Pines are usually pretty easy. This will just take longer. I would grub them, but I'm a one man operation here. adjusting the chains for each one and holding tension might be tough.
