457. Hay knife -- for cutting hay loose when it used to be piled rather
than baled. Now, livestock farmers use them when wanting to slice hay
off a contolled portions from a large round bale. It's way easier to
cut than trying to take a pitchfork and pull it loose.

459. A bluegrass or other small grass seed harvester. One would walk
through the knee deep grass, swinging it back and forth. In between
the large "teeth", there are small slots cut in the metal where the
stem of the grass is forced during the swinging action. As the bucket
continues to swing, the grass seed is stripped off the stem and
captured in the bowl.
