Peg Perego John Deere Gator XUV Extra-Large 12 Volt Ride-on, Durable Design for Kids 3-8, Green

Both can operate it well and prefer the faster speed setting. There is plenty of room for both to ride at the same time (ages 5 and 3). The 5 year old actually has more leg room on the Peg Pergo John Deere tractor, but he's slightly tall for his age. The boys run both of them nonstop for over 2 hours before it needs to be charged. The instructions frustrated my husband until we found a YouTube video. I highly recommend this for keeping them busy and happy but would but like I said earlier; the 5 (almost 6 year old has far less leg room than he does on the tractor which is smaller. The tractor is fast (on the higher speed setting) though so he doesn't mind driving it. The slower setting is highly recommended until they understand how to operate or if you have lots of things they can run into in your yard.
