OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Model 33 [Help identifying model and year]

Hi Scoee, and a warm welcome to the forum.
It's nice to have another Scott Bonnar owner on board, as we all like to learn new things and tinker here.

Your machine is a 16" Scott Bonnar Model 33 with a Kirby-Tecumseh HK25 2.5HP 4Stroke engine.
The model 33 was first introduced in 1960 and was still included in the SB Selected Equipment Range 1974-1975, though through some research, I have found that it is thought to have been discontinued in 1966.
Here is a pic of the 1974-75 range:


Once again Scoee, to OutdoorKing.
