kzp70 Posted October 22, 2013 Share Posted October 22, 2013 Hey everyone. I just started a job driving a 2012 Mack Pinnacle day cab PTO truck with mDrive for delivering bulk feed to dairies using a walking floor trailer. I work at night and sometimes I can't see that I am getting into a bad traction situation until I am already in it (dairies are not truck friendly environments, lots of loose dirt, feed scattered on concrete, dead ends and tight corners). If I expect trouble, I normally hit the power divider (is this the same thing as the "inter-axle differential" switch that I see on the freightliners I used to drive?). As soon as I hit the switch the horn starts blasting and I can't tell if the 2nd axle is kicking in. No warning lights, messages on dash or anything else. What is going on with this thing? Does having the PTO on or off matter? Thanks. Quote Link to comment Share on other sites More sharing options...
