The brush hoe has PTO-driven plastic bristles that
rotate on a horizontal plane, aggressively ripping
weeds from the soil (Fig. 5). Shields, hung above
the soil surface, protect the crop from .he rotating
brushes but allow soil to move into the crop row.
Because the tool is very aggressive and precise,
an additional operator (on the rear seat) is required
to steer the shields over the crop row. Cultivation
depth is modified with guide wheels and the threepoint
hitch attachment. Several row spacings and
brush configurations are available.
