OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Old Mower Pictures Can anyone tell me about this Vintage Mower?

Was told it was at least 50 years old

I cannot find another on the internet made by SER, I would be grateful for an info to help me identify this mower, thank you!

Hello RoRo

I feel the 'SER' is a red herring ...
I think it's 'SER.' - an abbreviation of 'serial number'

The USA produced, I guess, dozens of these 'Big Wheel' mowers,
some - like this one - a copy of the Yazoo drive system.

These Big Wheel designs never caught on in Australia, though
the Yazoo was imported.

Your machine's Tecumseh indicates to me this is a 1970s machine
(possibly a bit later). I think a North American forum might
reveal identification - but I do not think these were sold in AUS.

Hope this helps.
