Newbie to the forum. Just picked up my L3901 today. Got it home and put in the Summit 3rd function kit and the WR Long grapple as well as the saw haul. I’m ready to go to work.
I did almost the same. New L4701 just added the LA765 last week and today I installed the Summit 3rd Function. Put on a 66” Tomahawk Grapple and moved several trees I have wanted for a while. Great Day! I installed the Sawhaul too.
