聯合收割機 / 拖拉機 + 拖車

My son spent hours attaching the trailer to the tractor — the pieces click together satisfyingly and the soft tires make it easy to push around on our hardwood floors. He's already rebuilt it twice into different machines.

The mechanical functions actually work — the grain auger on the harvester spins when you turn the crank, which my kid thought was the coolest part. Over 1,000 pieces took us about three evenings to sort and build, and the little play figure fits right in the cab.

I didn't expect the mechanical functions to actually work this smoothly, but the tipper on the trailer really does dump. Over 1,000 parts kept my kid busy for days, and he's already rebuilt it into a second model. Worth every penny for a rainy weekend.
