ABSTRACT:
A toy pull-sled accessory for a self-propelled toy vehicle is supported for towing on a play surface by a forward friction pad and freely rotatable rear wheels. Friction with the surface is increased by a weight with a pivotally depending pawl movable along a ratchet rack from over the rear wheels toward and over the forward friction pad. Mounted for rotation on a rear wheel axle is a gear which periodically shuttles the rack forward against a rearward return bias to advance the weight.
