Not a mower but a few newspaper adverts which are quite interesting. There seems to be some swapping about regarding which mowers were best for a Royal garden. I have added the newspaper adverts.

In 1867, an advert said that R Brown’s ‘…New Patent B.B. Lawn mower has already been patronized by Her Majesty the Queen, for the Royal Gardens at Windsor Castle, Osborne, Kew, and Hampton Court; by His Royal Highness the Prince of Wales, for Sandringham…”. But, in 1869 the Sandringham gardener was said to favour a model by Ransomes. The 1869 advert by Ransomes, Sims and Head, Ipswich, stated that Mr W Carmichael, gardener to H.R.H. the Prince of Wales, Sandringham, said that “The [Automaton] Lawn Mower works most satisfactorily. I have tried the most approved models, but have no hesitation in giving yours the first place.”

In 1894 an advert stated that Thomas Green & Son were “…the only makers of lawn mowers appointed by Royal Warrant Makers to H.M. the Queen and his Royal Highness the Prince of Wales”.

How did they get this Royal Warrant? Was it by providing the royal residences with mowers over a period of time?

Many thanks for the information.

I have found an 1866 advert for Browns New Patent Mower that caught the eye of Royalty and was subsequently used at Windsor Castle, Hampton Court, Sandringham and others.

Another mower: In 2013, Zara Phillips MBE was heavily photographed by the press on a restored 1963 John Deere 110 garden tractor at the Chelsea Flower Show on the JD stand. (Cannot put a photo as they all seem to be under copyright).
