It's the middle of October, and Reuben, Tommy and Sarah have returned from their holiday road trip through France. But as there's a busy autumn schedule ahead, the team has a dose of the post-holiday blues.First on the agenda is clearing out the yard's barn as Reuben has a plan to sell old machinery at a local auction. But Reuben's vintage tractor is reluctant to leave and refuses to start. Sarah's lovingly painting an old plough with the hopes there's a buyer for this upcycled vintage machine. And Reuben and Tommy weld together a cow scraper in an effort to bag a good bid.Their biggest job of the autumn season is an intricate plumbing project which will be a first for the new business. Reuben's neighbours John and Rachel are trusting the young team to remove their decades-old septic tank and replace it with a state-of-the-art system. But when Reuben discovers the pipework is buried throughout the carefully tended cottage garden, they must work out how to carefully excavate the couple's prized box hedges.As Tommy is turning 18, he's old enough to fulfil his childhood dream to follow in his family's footsteps and become a qualified lorry driver. But before he can take lessons from his dad's cousin and haulier Neal, Tommy must pass a medical test.When the auction day arrives Reuben invites brothers 17-year-old Miles and 11-year-old Sidney to join the team for the sale. And as they roam through the lots, Sid spots a petrol buggy he likes the look of, and Miles admires the livestock on sale in the auction ring.When Tommy's 18th birthday arrives, the friends take him trials bike riding, Sarah goes on a secret birthday cake mission, and they celebrate his rite of passage together over a pint at their local.
