A rake is an agricultural tool with prongs or teeth set transversely at the end of a long handle; it’s used for gathering leaves, grass, hay, &c from the ground. It’s a period charge, found in the canting arms (German Rechen) of Rechenberg as early as c.1370 [Gelre 34v]. The rake is palewise, handle to base by default.
