Diddly Squat farmer Jeremy Clarkson has admitted that working without his right-hand man, Kaleb Cooper, was like a "slow mo accident". The 65-year-old Clarkson's Farm star had to hire new help - Harriet Cowan - in Kaleb's absence as he admitted that he was facing a "huge wake up call".

The former Top Gear star bought Diddly Squat Farm in Oxfordshire back in 2008 and has documented his journey of maintaining it on his Amazon Prime show. However, as the series four trailer shows, his trusty farm manager, Kaleb, had taken a break to explore a venture of his own. He travelled the UK on a one-man tour, The World According to Kaleb.

Speaking about the upcoming new series, which will drop the first episodes on May 23, Jeremy emotionally shared: “I did do some of the farming for the first time ever, completely on my own, with Kaleb not being around. I had to take care of the pigs on my own. I had to take care of the cows on my own, and I had to get the crops planted on my own."

He continued: “When you’re doing it completely on your own – well, things had to be redone a few times! When you have planted an entire field and it’s taken days, it shouldn’t have taken days, but it did take me days – you finally get it in, and then three weeks or a month later, absolutely nothing grows out of it.

“That’s a slow-motion accident, and it’s extremely disheartening when you’ve worked your socks off and nothing grows. Nothing. Not one single thing grew out of the soil." Jeremy concluded: "That, in terms of farming, was my big wake-up call.”

Kaleb and Jeremy often butt heads while working on the farm together, particularly around harvest time - with Kaleb putting it down to Jeremy's "incompetence".

The farm hand previously said: “Jeremy and I argued quite a bit in harvest because it was so stressful for me trying to do my very best again as a contractor. It was pretty tough mentally. The problem with the harvest was because I’m still young, I’m 26, I think a lot of people can doubt me sometimes.

"I doubt myself sometimes because I think everyone does ask themselves if they’re doing things right. Jeremy really enjoys doing the harvest, but he’s a pain. Life would be easier if he wasn’t there during harvest, just because he’s a bit incompetent!”

Clarkson’s Farm series 4 comes to Prime Video on Friday, May 23.
