Abstract
A garden sieve for a wheelbarrow has a collar frame adapted to conform to and fit loosely on the rim of a wheelbarrow. A sieve frame connected to the collar frame supports a wire screen adapted for sifting granular material. A motor can be connected between the wheelbarrow and the sieve to reciprocate the wire screen. The frame can include a partially removable gate for the removal of strained material and can include roller bearings to reduce friction between the sieve and the wheelbarrow.
