Two or three weeks back I heard a chainsaw screaming for help in my close neighborhood.
Took a walk to see what the neighbor is cutting, he noodled 15-20" diameter knots with a MS170.
I asked politely whether I am allowed to join the party, he responded "Yes, but it is not necessary, I have time".
I walked home, fueled up my PS-7900, touched up the chain and went back to the neighbor.
Withing a few minutes there was a huge pile of noodles blocking his driveway, the PS-7900 was howling like a werewolf in heat (the sound echoed fiercely off of the surrounding houses, sounded really great), and his facial expression was simply priceless.
I asked him whether he would like to give my saw a try, he quickly declined.
After all his knots were reduced to little pieces and noodles i drank a beer and chatted with him a little.
I didn't ask for anything in return, having fun noodling with my PS-7900 was worth a tank of fuel and oil.
I did take all the noodles home as my neighbor didn't need nor want them, I gave them to my dad for his rabbits.
When I buck my uncles firewood logs, usually beech, he reimburses me my material costs in cash and offers me drinks and food.
