EVA wheels are the defining hardware on this tractor. Their resilient running surface puts something softer than bare molded PP between the vehicle and brick, asphalt, cement, or a wood floor, while three wheel diameters support the tractor-and-trailer profile. The 14 by 13.5-inch trailer detaches, so a child can choose between hauling toys and maneuvering a shorter vehicle. Twin 25W motors move the 49-inch assembly from 1.6 to 2.2 mph on a 12V 7Ah battery. Manual controls give the child the wheel; the parent remote adds three speed levels and an emergency brake, and it requires two AAA batteries that are not included. A gentle start helps the 66-lb-rated tractor pull away without snapping the trailer load backward. Wireless music adds sound without taking over the dashboard. Intended for ages 3 to 8 and built from PP, EVA, and metal. Key Features Specifications Note: Actual product color may vary slightly from the images due to lighting and display settings.
