Wooden 3D construction kit — Kirovets K-7M tractor

This original 3D wooden puzzle from EWA Eco-Wood-Art represents the legendary Kirovets K-7M tractor. It is a highly detailed mechanical model made from high-quality plywood. First, you assemble it yourself from precisely laser-cut parts, and then you can enjoy its fully functional mechanics. It is not just an ordinary puzzle – once completed, you get a realistic moving tractor model with a wind-up mechanism.

The model impresses with its robust design inspired by the real Kirovets agricultural tractor. Precisely cut wooden parts hide a clever rubber-band powered mechanism that allows the tractor to move both forward and backward. Under the opening hood you will find a realistic inline six-cylinder engine, and the model also features opening doors and a start-stop system.

How does the movement work?

Inside the model there is a rubber-band powered mechanism. When wound up, the rubber band stores energy. Once released, it slowly unwinds and transfers the energy through a system of gears that sets the tractor in motion.
After winding, the model moves on its own and works completely without batteries – purely mechanically.
