ABSTRACT:
The flexible hose of the vacuum trash collector is supported by a leaf spring boom secured to the trash collector canister by the boom height adjustment mechanism. A nozzle at the end of the hose picks up the trash. A hand crank, driving a threaded reciprocative coupling, changes the angle of attachment of the boom to the canister, to raise and lower the boom and thereby allow the operator to set the nozzle height to a comfortable operating position while in the field and without the need to use tools or to dismantle the boom attachment mechanism.
