As a toy designer and wood lover, I designed different vehicles and produced them with a specially developed method. All the models are made from beech wood and used no metal parts, only wood, glue and water based varnishing.
The Bulldozer is a six-wheeled hardwood toy. It is sanded and oiled to a fine finish. The shovel can be moved up and down. The bulldozer can easily be loaded onto the Low Loader. https://www.thedispensary.org.uk/shop/craft/botton-village-crafts/toys/wooden-toys/item-499
