The Fowler Gyrotiller was a fore runer of the power harrow or rotavator, buit by John Fowler & Co. of Leeds from the 1920's. Several models were produced, and most early machines were used by ploughing contractors for breaking up virgin land, as they would grub up small bushes and trees. They were hugely expensive and thirsty, and a number are believed to have been sold on Hire purchase like the steam engines. Others were operated by a Fowler subsidiary, on a contract hire basis, at a rate per acre.
History[]
The Gyrotiller was invented by a Norman Storey in Porto Rico, a Sugar cane plantation estate manger. Charles Henry Fowler agreed a exclusive licensing deal with Storey for use of the patented design, in 1925.
225 hp / 170 hp Gyrotiller[]
The First machine left the factory in October 1927 for the West Indies. early machines had 225hp Ricardo petrol engines, but they were replaced by MAN diesels of 170 hp or 150 hp that used a lot less fuel. The tractor looked similar to the early Holt tractors built by Ruston and Hornsby for the army during WW I under licence, with tracks and a front 'steering' wheel. An example survives and has been shown at Great Dorset Steam Fair - photo here
Only one example survives, which is now back in full working order after being in storage fora number of years. The identy of the machine is rather confused with Fowler id plates for another machine and a registration number that is believed to be from a sister machine operated by its owners during its working life. -
The early machines were superseded by the later models mounted on crawler tractors.
