In this animated show whose main stars are talking tractors and farm vehicles, the latest news down on the farm is that Gracie the Quad Bike is due for a check up at the garage. Only she doesn't want to go. Gracie has been talking with old Rusty, who believes that once your mechanical problems have been found out, you end up stuck in the shed. It's up to Massey Ferguson to save the day once again, by helping persuade Gracie there's no reason to be scared of the doctor.
No good comes of going to get fixed. They find things wrong with you, and next thing you know you start living in a shed all the time like me.– Rusty (Jason Hoyte)
