Excavator Copper Cookie Cutter

Every small boy's dream - actually I'd like to have a go of one these too, an excavator, JCB or digger copper cookie cutter, approx 11cm x 16cm. This is a tracked excavator, you can get wheeled ones too but the caterpillar tracks make sure they don't slip on muddy ground. The wheeled ones are easier to move as you can drive them on roads, if you drove the cat tracks on the road they'd just eat up the tarmac. This happened in front of the office when we had great excitement when a mini one of these was delivered and the truck couldn't get under the railway bridge. They wouldn't let us drive it though which I though was really mean.
