OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Old Scotty

Just dug this lovely weapon out of the old-man's shed
Any info would be great
ID tag says... model 40 sn.09545
regards Pest

Hi Shedpest, and a warm welcome to the forum. It's always great to have another Scotty owner aboard, as we all love to learn new things and tinker here.

You have there a Scott Bonnar Model 40 Electric, which would be a single phase 240V 50Hz motor; it should state the horsepower somewhere on the motor data plate. Your post does not give us the cutting width, but I would presume it is a 14" cut, in which case it was known as a "terrace mower". The Model 40 (Electric and Petrol) were first produced in 1960.

Have a search of the Scott Bonnar topic in "Lawnmower Frames" in the main forum area, you will find some interesting info there.
Once again

Thanks for the info Deejay (even if I put it in the wrong thread)
Yes it is a 14in as you presumed.
I have stripped it down and am waiting for the cylinder to be sharpened and a new bed blade.
I was told there was not a lot of blade on the reel, so adjustment might be an issue,can you pack the bed-knife blade down to get more adjustment?

Hi Shedpest, No probs,I have moved your original post and replies to the Scotty topic.

In regards to your query; No mate, you can't pack the bedknife to get adjustment, the bedknife is fixed with special screws to the soleplate, which in turn is attached by bolts to the mower frame, so it is the cylinder reel that adjusts up or down to it....in fact the reel does not contact the bedknife at all; there is a minute clearance between the two, however it will cut paper all along its length when correctly set up.

This is a little tricky to do at first, but you will succeed providing the reel bearings are not worn and are running true.

I have ordered new bearings as well,so it will get the whole birthday it has not had for 20+ years

As this thread is over 12 months old I will now close it for the archival value....If any member has anything to add, please send me a PM.
