I'm definitely missing what context informed these lines, but their tone, as well as that of "Come the sweet kinks of the fist, from the full flower," remind me of working/playing in dirt: pulling up weeds, picking up a muddied hose, earthy skid-marks across the hands. There's something less bleak and somber about this section (or stanza? I'm not sure what it's called) in comparison to the "Earth is eating trees, fence posts" and "industrial barns, out of rain, out of bus ride" that make up the first half of the poem.
EDIT: I've just now learned that a "reed" is a part of a shovel! This whole time I've read it as the reeds of a lake.
