The present invention involves a seed firmer with a pusher attachment that extends the life of the seed firmer. The seed firmer construction provides a replaceable tip or end for extending the life of the firmer, generally having two components that degrade with use, the flexible arm and the embedding pusher. The flexible arm generally lasts much longer than the embedding pusher portion because the pusher wears against the ground and eventually wears away. Embodiments of the invention include an embedding pusher portion that has a stop and a guide for accepting a replaceable extender. Other embodiments include an embedding pusher portion that engages the rest of the firmer arm. Thus, the portion of the firmer that wears down may be easily replaced which extends the life of the firmer, multiple times over the useful life of the flexible arm. |
