Hi all, newbie here. Our club (snowmobile) bought a 13 850d with tracks for trail work, shuttling in tools and people for trail maintenance etc. I have 2 questions, 1 is; What setting would I use for the speedo to calibrate for the tracks? and 2; is there a clutch adjustment to allow this machine to pass someone walking? This thing is way too slow in my opinion. Thanks in advance. We love this machine, hoping it's an adjustment issue and not a normal condition.
