ABSTRACT:
A toy mechanical digger includes a base frame member, a longitudinally-extending base beam pivotally mounted on the base frame for manually-actuated, 360.degree. slewing action relative to the base frame, a seal longitudinally slidably mounted with respect to the base beam; a primary boom having a pivoted end, and intermediate end, and a remote end, the pivoted end being pivotally mounted to the forward end of the base beam, such that the remote end can be raised and lowered, the intermediate end pivotally mounted to the forward end of the seat such that forward and rearward longitudinal sliding movement of the seat is linked to the lowering and raising movements, respectively, of the primary boom; a secondary boom having a pivoted end and a remote end, the pivoted end mounted on the remote end of the primary boom for pivotal movement relative thereto. A bucket is pivotally mounted on the remote end of the secondary boom, whereby the primary boom, the secondary boom and the bucket can be manually actuated to dig and dump. Two separate, manually-actuable, mechanical operators are mechanically connected to the secondary boom and to the bucket. A user, sitting on the seat can by manual operation of the seat and the two operators cause the primary boom to pivot with respect to the base frame, cause the secondary boom to pivot with respect to the primary boom, and cause the bucket to pivot vertically with respect to the secondary boom.
