Clarkson’s Farm Star Harriet Cowan Joins Forces with Izzy Hammond in Top Gear Crossover Adventure

In an unexpected and delightful crossover, Harriet Cowan, the breakout star of Clarkson’s Farm Season 4, has teamed up with Izzy Hammond, daughter of Top Gear and The Grand Tour icon Richard Hammond, for a unique collaboration that bridges the worlds of farming and motoring. The duo’s chemistry was showcased in a recent DriveTribe YouTube video, where Cowan, a 24-year-old farmhand from Derbyshire, attempted to teach the 25-year-old Hammond the art of driving a tractor. This lighthearted yet meaningful project not only merges two of television’s most beloved franchises but also highlights the growing presence of women in traditionally male-dominated fields like agriculture and automotive media.

A New Face on Diddly Squat Farm

Harriet Cowan burst onto the scene in the fourth season of Clarkson’s Farm, which premiered on Prime Video in May and June 2025. The series, centered on Jeremy Clarkson’s often chaotic attempts to run Diddly Squat Farm in Chadlington, Oxfordshire, introduced Cowan as a temporary replacement for fan-favorite Kaleb Cooper, who was away on a promotional tour for his book. Cowan, with her infectious enthusiasm and no-nonsense approach, quickly won over viewers as she navigated the challenges of farm life alongside Clarkson, farm manager Lisa Hogan, and the rest of the Diddly Squat crew.

Her role was more than just a stand-in; Cowan brought a fresh perspective to the show, tackling tasks from crop management to livestock care with a blend of skill and humor. Her presence added a new dynamic to the series, which has become a global hit for its mix of agricultural insight, comedic mishaps, and heartfelt moments. Fans on X praised her contributions, with many noting her ability to hold her own against Clarkson’s larger-than-life personality. “Harriet’s a star—she’s got the grit and the charm to match Kaleb,” one viewer posted, echoing the sentiment of thousands who embraced her as a new fixture on the farm.

The DriveTribe Crossover: Tractors and Teamwork

The collaboration between Cowan and Izzy Hammond, released on DriveTribe’s YouTube channel in September 2025, marks a playful intersection of Clarkson’s Farm and the automotive world that Clarkson, Hammond, and James May built through Top Gear and The Grand Tour. DriveTribe, the digital media platform co-founded by the trio, has become a hub for car enthusiasts, and this video offered a refreshing twist by blending rural life with motoring culture. In the 15-minute clip, Cowan takes on the role of instructor, guiding Hammond through the basics of operating a tractor—an experience that proves both challenging and hilarious.

The video opens with the pair at a rural location, surrounded by a fleet of red Massey Ferguson tractors, a nod to the iconic machinery featured on Clarkson’s Farm. Hammond, who has grown up in the shadow of her father’s high-octane career, admits to being out of her comfort zone. “I’m used to cars, not tractors,” she laughs, as Cowan patiently explains the controls. The lesson takes a comedic turn when Hammond stalls one of the tractors, prompting her to quip, “All the farmers are going to laugh at me!” Cowan, ever the supportive coach, reassures her with a grin, “You’re doing better than Jeremy would.”

The interaction between the two is a highlight of the video, showcasing their easy rapport and shared sense of humor. Beyond the tractor-driving lesson, the pair engage in a candid conversation about their respective journeys into the public eye. Cowan opens up about her unexpected path to Clarkson’s Farm, revealing how she landed the role after being scouted by the show’s producers. “I don’t know if they were specifically looking for a woman, but it felt amazing to be asked,” she says. “To go in and show women’s power on an agriculture TV show—where you don’t often see many women—was really special.”

Breaking Barriers in Agriculture and Media

Cowan’s comment strikes at the heart of her impact on Clarkson’s Farm. The agricultural industry has historically been male-dominated, with women making up only a small percentage of farmers in the UK. By stepping into a prominent role on one of Prime Video’s biggest shows, Cowan has become a role model for young women aspiring to enter the field. Her work ethic, coupled with her ability to navigate the chaos of Diddly Squat, has challenged stereotypes and brought visibility to women in farming.

Similarly, Izzy Hammond represents a new generation in the automotive world. As the daughter of Richard Hammond, she has carved out her own space in media, contributing to DriveTribe’s content while pursuing her passion for cars. The crossover video is a testament to her willingness to step outside her comfort zone, just as Cowan has done in agriculture. Together, they embody a shift toward greater inclusivity in their respective industries, proving that determination and adaptability can break down barriers.

Behind the Scenes: How Cowan Joined Clarkson’s Farm

During the DriveTribe video, Cowan shares more about her journey to Diddly Squat. A Derbyshire native with a background in farming, she was working as a farmhand when the opportunity to join Clarkson’s Farm arose. The show’s producers were looking for someone to fill in for Cooper, whose tour commitments left a gap in the team. Cowan’s experience, combined with her natural charisma, made her an ideal candidate. “It was a bit surreal,” she admits in the video. “One day I’m working on a farm, the next I’m on set with Jeremy Clarkson, trying to keep up with his banter.”

Her time on the show wasn’t without challenges. Season 4 saw Diddly Squat grappling with extreme weather, bureaucratic hurdles, and Clarkson’s ambitious (and often impractical) ideas. Cowan’s ability to stay calm under pressure—whether wrangling pigs or managing crops—earned her respect from both the crew and viewers. Her dynamic with Clarkson, in particular, became a highlight, with their playful exchanges reminiscent of his dynamic with Cooper.

What’s Next for Cowan and the Crossover?

As Clarkson’s Farm gears up for its fifth season, currently in production in Oxfordshire, fans are eager to know whether Cowan will return. While Prime Video has not confirmed her involvement, her popularity suggests she could play a significant role. The show’s creators have hinted at new challenges for the Diddly Squat team, including potential expansions to the farm shop and ongoing battles with local regulations. Cowan’s agricultural expertise and on-screen presence would make her a valuable addition, whether as a regular or a guest.

The crossover with DriveTribe has also sparked speculation about future collaborations between the Clarkson’s Farm and Top Gear universes. Fans on X have called for more joint projects, with some suggesting a full episode featuring Clarkson, Hammond, and May tackling farm life. “Imagine Jeremy, Richard, and James trying to run Diddly Squat for a day,” one user posted. “Harriet and Izzy would have to save them!”

For now, Cowan and Hammond’s tractor-driving adventure stands as a charming bridge between two worlds, showcasing the power of collaboration and the appeal of authentic, relatable personalities. As Cowan reflects on her experience, she remains humble about her newfound fame. “I just want to keep farming and maybe inspire a few people along the way,” she says in the video. With her star on the rise and a potential return to Clarkson’s Farm on the horizon, Harriet Cowan is proving that she’s more than just a temporary replacement—she’s a force to be reckoned with in agriculture and entertainment alike.
