Muck tools
One tool lives on this shelf, and it earns the space. A weighted drum with hooked teeth for the roots and the soft black layer the cutters cannot reach.

Muck Razer, rolling tiller for roots and muck
★ 4.3 (259)Cutting stalks back opens the surface for a few weeks, but the roots stay anchored down in the sediment. We built this rolling drum with curved teeth to dig beneath the muck layer. You roll it from the dock or the bank across several passes, loosening what our cutters cannot touch.
