Insect Sifter

| View Cart ⇗ | Info

The rear end of the machine is mounted upon two wheels. A trough, with a runner-like bow, containing some adhesive matter, is suspended upon each side of the row. A vibrating arm or beam, carrying wisps or brushes, is adjustably suspended form the farm, and as the machine is pushed along the row of plants the insects are shaken into the troughs, from which they are unable to escape.
