Keith Wannan, 34, died last week after his limbs were caught in the machinery at Foodie Farm, near Cupar, Fife.
Farm owner John Orr told the Daily Record newspaper: "We are just trying to put our lives back together. I can't say any more - I am not in a fit state."
Keith's former teacher Peter McKinnon, farm resource manager at Elmwood College, also told the paper: "This tragedy will be felt hard across the area. It doesn't mean someone has been careless or negligent - it's just a terrible tragedy. He was a very sensible young man and very competent in his work.
"These machines are expensive pieces of kit at around £70,000. He was very familiar with them. But something can happen so quickly."
