Washing machine appliance having a removable agitator

A washing machine appliance comprising:

• a tub;
• a basket rotatably positioned within the tub;
• an impeller base rotatably mounted within the basket and defining a rotation axis, the impeller base comprising
• one or more impeller fins extending radially outward from the rotation axis, and
• a mounting face disposed radially inward from the one or more impeller fins, the mounting face comprising a mounting bracket defining one or more attachment slots extending vertically;
• an extended post removably attached to the impeller base to rotate therewith, the extended post comprising
• a base body extending along the rotation axis between a bottom end proximal to the impeller base and a top end distal to the impeller base, the base body defining an interior cavity from the bottom end to the top end,
• an auger fin extending radially from the base body between the bottom end and the top end, and
• a mating face disposed on the bottom end, the mating face comprising a mating collar defining one or more attachment rails corresponding to and selectively received within the one or more attachment slots, the attachment rails extending radially outward from the mating collar;
• a connector bar selectively received within the interior cavity and extending along the rotation axis between a lower end and an upper end, the lower end comprising a connector tab to slidably engage the impeller base, the connector tab holding the extended post against the impeller base;
• and
• a post cap selectively covering the interior cavity of the extended post at the top end,
• wherein the impeller base further comprises an internal collar disposed radially inward from the attachment slots and received within the interior cavity of the base body,
• wherein the internal collar defines a secondary slot to receive the connector tab therein,
• wherein the mating collar further comprises a bottom ring at the bottom end to receive the internal collar, and
• wherein the connector tab and secondary slot are disposed above the bottom ring.

• and
• a post cap selectively covering the interior cavity of the extended post at the top end,
• wherein the upper end of the connector bar comprises an enlarged key held at the top end of the base body, and
• wherein the post cap holds the enlarged key to selectively direct the connector bar about the rotation axis.
