Micah's grandfather is convinced that his rusty, trusty, fifty-year-old tractor will make it through another haying season. But Mr. Hill of Hill's Tractor Sales is doing his best to sell him a brand-new tractor. He even wagers twenty jelly doughnuts that Grandpappy's old tractor will break down. Will Grandpappy buy a new tractor to replace his faithful old friend?
This charming, multigenerational story offers a solid lesson in friendship and trust.
