DIY mini rice field tractor with complete wood material with crank start and cart

Materials from wood and plywood used for construction.
The drive uses a DC motor / toy battery car circuit with 12 volt battery power.
It can be climbed by two children, it is quite strong, we also attach a spring to the axle so it is rather comfortable when walking.
can play mp3 bluetooth from a connected cellphone through a device that is behind a small black cart is a bluetooth connection device.
