I have just found this website,

An early and probably the biggest Rotavator, the Fowler Gyrotiller. Its a bit bigger than my Mantis electric tiller. I saw one of these working in 1936, the firm I worked for in the late 1940's owned the yard where Fowler's serviced these monsters. The engine weighed ten tons and the twin cylinder blocks (three of them) weighed two tons each. The piston's were the size of galvanised dustbins. I understand that they were ship's diesel engines. The one I saw in 1936 shook the ground as it moved along the road. The tines were about 30 inches long (working length) mounted on large horizontal wheels which were lifted on a giant hinge when turning on the headland.
