James Clark, from the Wyton Mower Centre, decided to make his own tribute to the NHS while he was cutting the grass.
James, along with two-year-old daughter Pheobe, cut the letters out using a ride-on tractor in a field at King’s Ripton.
His wife Katie is a nurse at Addenbrooke’s Hospital, in Cambridge.
Mr Clark said creating outdoor spaces was necessary because “all our key workers need a space to unwind after a stressful day or night at work.”
Wyton Mower Centre is offering a 10 per cent discount for NHS staff.
