Hello ODK history lovers
The Model 72 (720 Series) was Scott Bonnar’s first high-arch
lawnmower. Introduced in late 1971 for the 1972 season,
it would be made under SB’s new owner Electrolux, acting in
Australia as Flymo-Scott Bonnar.

It was an instant hit and a worthy competitor to the popular
Victa VCs of the early 1970s. The 720 Series would also
appear under various names, the most notable being ‘Viking’
– I guess in honour of SBs Swedish owners ...?

Maybe it was also a pun name to 'Lawn King' ...?
Outdoor King members decide ...

The Model 52 (520 Series) appeared later – c1977 – and would
be, essentially, an economy version of the Model 72. The chassis
designs were slightly different but they shared the same 18-inch
cutting width. The Model 52 would also be branded as a Lawn King
and Cabana.

Originally the Model 72 was the flagship sold against the mid-arch Model 49.
The Model 52 became the replacement for that model by the late 1970s.
