It's a Flymo.
... But with less flying capability.

The angular styling and first model Quantum suggest mid-late 1980s...
an interpretation of James Bond's Lotus Esprit I guess.

Not an overly handsome machine.
[I love the ornate stand behind it though]

p.s. it's quite a good image there.
The boring angular concrete and mower contrasted against
the circular, radiating flywheel cover and ornate stand.
