Stephen Sandys, 64, had left his house to feed his cattle on Pinstraw Farm in Eridge Road, Groombridge, but police were called at around 22:30 when he did not return.
His body was found in a field with his Aberdeen Angus cattle. He was declared dead at the scene.
A bull was shot dead by police.
Neighbour Brett Walker told the BBC: “He was a super guy, and never had a bad word to say about anybody.”
A spokesperson from Sussex Police said: “At this time we’re not treating the death as suspicious.
“It is believed the farmer may been trampled by livestock.”
