OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Reel-Type Mowers SB 45 adjustments and restoration

Hello, I have recently purchased a Scott Bonnar 45058 cylinder mower S/N 3951115, powered by a Tecumseh engine H30-35311S Ser 0151B.
I don't know anything about the history of this unit, nor do I have any idea of its age. I paid $240.00 for this mower which may or may not have been too much.

I've enjoyed reading the forum posts here and I am confident I can get the unit working properly with a bit of advice and perseverance.

The engine starts easily and the mower actually cuts grass although the blade setting seems to be poorly adjusted.

I tried to adjust the reel down towards the sole plate but I appear to have run out of adjustment on the two srews. The blades don't look too worn to me so perhaps I am doing something wrong.

Anyway I thought I'd begin this thread with a few photos and update it as I progress.

Thanks so much for this forum; I have enjoyed reading through the various restoration posts.


The catcher, not in this picture, is in pretty good condition.


Perhaps a trained eye can give me an opinion on the state of the blades.



The chains can be easily adjusted for tension.


There is no throttle cable just this lever on the engine.



This is one of the blade adjusting screws. As you might be able to see the adjustment is at the top of the elongated hole. The blades do not appear to be able to be set lower and they certainly don't cut paper.


The Tecumseh engine.


Should there be a housing over the clutch and lever?


Thanks again.
