A snowplow.

A snowplow from Frost’s era.

Frost is really making fun of the idea of a snowplow – plows are typically used to prepare a farm field for growing. However, snowplows only push snow out of the way… And that snow eventually melts (which it would do anyway). So, coming from Frost’s 1920’s point of view, when cars weren’t frequent, plowing snow seems kind of pointless.

It also might be worth noting that this whole poem is in iambic tetrameter – there are four “feet,” or sections of two or three syllables (usually) consisting of syllables both accented and unaccented. A foot must include an accent, much like music. Each of these are iambs, which are feet whose syllables follow an unstressed-to-stressed pattern.

See, with stress, how this line flows:

A plow, they say, to plow the snow.

Now, divided into feet:

A plow, / they say, / to plow / the snow.

These four iambic feet that make a line, then, are following the second most common meter in English poetry, iambic tetrameter.
