A level indicator for a snow plow assembly has a reference wand and a pendulum guage pivoted to the reference wand. The reference wand has a bend at a top end with a reference mark to lie over the pendulum. The pendulum guage has a counterweight to dampen its swing and has an indicator. The indicator aligns with the reference mark in a level position of the snow plow assembly and the swing of the pendulum is limited by interference with the reference wand between extreme positions where the snow plow assembly is tilted.
