Weatherby sent him to stand at stud at George Tattersall's stud, Dawley Wall Farm. In 1838, he was sent to East Acton, where he stood for a fee of £30 (). However, Weatherby died and Sir Hercules was sold to Sydney Herbert (later Lord Lea). In 1844, Herbert sent the stallion to Tattersall's Willesden Paddocks, where he was available to public mares. Soon, however, Herbert broke up his stud and sold Sir Hercules to Mr. Phillips of Bushbury Stud, where the stallion eventually died at the age of thirty.
