When my son was really young, our local park had these digger toys attached to concrete pylons that the kids could actually dig with. I saw more than a few toddler brawls there when everyone didn’t get their turn. If you have a kid that likes to dig holes, this is the Christmas gift for them.
This Caterpillar digger has tank treads on the bottom to make it easy to move around. It also has a seat and looks like a real backhoe. It has a mechanical action controlled with a big lever that actually allows it to dig.
It’s not cheap at $400, but this little beast is made from steel and should last for generations. It looks like the sort of toy your kid could give to his kid 25 years from now.
