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]

Thanks DeeJay and Grumpy,

Wow, I thought it must have been a few years old ... but now I know it's at least 47 and as much as 54 I'll treat it with a bit more reverence.
And I haven't found the Scott Bonnar ID plate yet - only the Engine Plate

Any advice on items I should look at servicing / oiling / replacing, given that it is of this age and has been in storage for 23 years.

I've changed the engine oil with 30 grade, the chains look plenty lubed, and I've put a drop of oil into the ?Thrust Bearing (perhaps) - along side the clutch.

Cheers

Scoee
