An anti-rollback mechanism for a material handling implement including a unit pivotally mounted on the outer end of the boom of a vehicle is disclosed herein. The anti-rollback mechanism includes a member that is moved with the boom to indicate the position of the boom and prevent actuation of a manual control lever that forms part of the hydraulic circuit for pivoting the unit on the boom. The anti-rollback mechanism incorporates a manual override to allow the operator to tilt the unit on the boom even though the boom is in the completely raised position.
