John Deere Tractor Engine

John Deere

A take-apart John Deere tractor engine children dismantle and rebuild using the child-sized tools that store under the bonnet. Reassembling the parts reactivates the lights and starter, so young mechanics can check the oil, change the air filter and swap wheels before starting up. Builds fine motor skills and problem-solving. 56 pieces; requires 8 AAA batteries (not included). Best from around three years.
