Using these Maisto mini work machine tractors is easy. Just roll them on flat surfaces and they'll move freely. You can also attach different implements to them for more fun. When it comes to maintenance, keep them away from water as the die - cast body and plastic parts can get damaged. If they get dirty, you can use a dry cloth to wipe them clean. Since the styles are assorted, don't be too disappointed if you don't get your preferred one at first. And remember, each tractor is sold separately, so if you want more than one, place multiple orders or visit your local Toyworld store.
