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 to lie over the pendulum and space a reference mark away from the mounting end of the reference wand. The pendulum guage has a counterweight to limit its swing and has an indicator and limit means in the form of a three-peaked crest. The center peak lines up with the reference mark in a level position of the snow plow assembly and the outer peaks limit the swing of the pendulum between extreme positions where the snow plow assembly is tilted.
