Chicken Tractor

Today Canaan demanded my help in locating one of his seven million toys (number is an approximation). The toy he wanted? He refers to it only as the "chicken tractor". He has both tractors and chickens but nothing that combines the two and he isn't giving me a single clue as to what it could be. However, I'm definitely supposed to find it. King Arthur had the Holy Grail-I have the Chicken Tractor.
