Here is another 20's reel mower called the JP Super Power Mower with a little info as follows:
Of the motor mowers produced by JP in the 1920s and 1930s by far the rarest and, perhaps, most interesting is the 24" JP Super Power Mower. This was unusual because it featured a water cooled four stroke engine with an open topped water hopper that resembles a small cauldron or cooking pot! In fact, cooling was achieved by a combination of the water jacket and air forced around the outside of the combustion chamber by an impellor built into the main engine unit.
JP prided itself on the quality of its design and manufacture and this included making the mower easy to maintain. The mower was designed so that the entire engine unit could be removed easily for maintenance and repair. JP brochures of the period also claimed that this would allow the mower to be used by hand but it is doubtful if this was really practical because, even without its engine, the mower would have been large and heavy.
