This glyph resembles the small seal script form of the Chinese character chè 屮. Xu Shen explains that it is a pictograph of a branch¹. It was used as a classifier (counter or measure word) for shafts.
Animals were attached to the shaft in teams. The suggested translation is therefore, the noun team.

In the Indus texts, this symbol is normally associated with bovines. However, in the context of a mixed group, it may refer to other animals used for transport.
