OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers scott bonnar 45 mower

Hi Steve, as usual, good advice from Grumpy there, mate. If in doubt, use a fine rake and drag it all back into the garden.
For my edging I use a Victa Tilt-A-Cut which throws the grass and litter forwards, so I don't have much of a prob there.
For ferrous metallic objects, I removed the magnet from an old hi-fi speaker, tied a length of strong garden twine to it, so as I can drag it over the lawn, if I suspect I have lost a nut, bolt or screw.....better safe than sorry.

thx deejay for your reply about how much can a cylinder cutter handle.i have a question what color was the cylinder cutter on the SCOTT BONNAR 45 MOWERS the 1 ive just about finished has a kirby 2.5 hp and its orange in color can u confirm that the cylinder cutters were orange on the early scott bonnar 45's kind regards steve....

Hi Steve, you are quite correct there, mate, they were the same colour orange as the Briggs, and also the orange on the handle decal, on the later machines. Personally, I prefer Fire Engine Red on the cylinder reel, and had mine done in 'Powder Coat". I have never been a big fan of the orange colour!!

g day!All well deejay sorry to disapoint but im gunna stick to the original color merry chistmas steve.....

i notice that the clock time is different to the post time anyway cheers

Hi Steve, and Merry Christmas and a Happy New Year to you and yours.....Yeah mate, once I replaced the Briggs engine with a Honda, I lost the originality with my machine, so I powder-coated a few of the parts in red, to match the engine cowling colour. But as yours has the original engine, orange will look the part!

did the powder coating set u back much deejay? steve...

Hi Steve, I had to have the cylinder reel sand blasted first; (after carefully masking the areas where the bearings sit) and from memory that cost around $20.00. The other parts I stripped myself, and the powder-coating cost around $45.00.
That was a few years ago, if you are thinking of doing the same, I would get a quote first. The reel did look better than new afterwards.
BTW...The reel needed sharpening, so I had it powder-coated first, then spin ground after.....

some pics of my SB 45/17 with original kirby 2.5 hp model number 45 00867 made in 1968 when scott bonnar released the 45 range of cylinder mowers merry chistmas steve...

Well done with that machine, seeing those two pics made me excited in the pants area!

Steve that is a fantastic job you have done on the Scott Bonnar. It looks better than a new one on a job well done.

Hi Steve, I wish to echo Bruces comments, just brilliant!!
You should feel very proud of your work, just like a bought one!!

thanks for the kind comments all it went from just a clean up to a full pull down this 1 was not as much work as it was in good order the fuel tank has a internal filter as the tank had dried leaded old fuel and i think rust but a few weeks of clean clean clean i got it to a usable state with filter and replaced o rings in fuel tap merry chistmas steve...

Hi there Deejay (and others), I have a Model 45 and a Diplomat (ugh!) and have long lost patience on the cruddy old Briggs and Stratton vacuum choke carby system etc. For the 45 ...I can purchase for $285 a new (2008) 3hp B&S from a mower shop who bought it for a customer job which didn't go ahead but I feel I would rather go to the Honda. Any advice? And what model Honda did you use or recommend? Any issue with shaft sizes, keyway, shaft height and centering from the base/mounting plate? Throttle cabling etc? Is there a forum on how to do this?
Any pointers gratefully received.
Phantomguy.

Hi Phantomguy and to the forum. I am sure that Darryl (Deejay) will be able to help you with the information regarding fitting a Honda to your mower.

The mounting holes will line up without any trouble at all and all you will have to do is make sure that you get the correct shaft on the Honda engine. I am sure that Darryl will give you any other information that you will need soon.

Hi Phantomguy. and a big warm welcome to the forum. I have had a hectic festive season and I am sorry for the delay in response to your question.

On my Scotty I have a Honda G100 2.5HP. These engines have been superseded by the GX range, and are apparently very strong for their size.(and start first pull)!!

You can click on the model range on the right to see all the various sizes.

I had my Honda fitted by a local engineering firm in Wagga, (Judds Engineering) who also happen to be the Honda dealers for this area. As far as I know, there were no probs encountered, the horizontal engine shaft mated properly with the cylinder clutch, and even the 4 bolt holes that attach the engine, aligned perfectly.

I actually had only 2 problems with the original engine.....one was called Briggs and the other called......
Viva La Honda!! he he!

What a great restoration.. Awesome attention to detail!

Can anyone tell me the paint brand, colour name and finsh type used on Deviosi's resto? The green and orange?

Eg.
Galmet - Brunswick Green - Metallic Finish

Septone - Chevy Orange - Heat Proof Finish

Is it necessary to use a heatproof paint for the engine or can I use say a regular galmet rust proof flat colour? I want the cutting reel and engine the same colour though seems silly to use heatproof paint on the cutting reel. I would rather use a specific rust proof paint on the cutting reel such as galmet, septone or killrust and if used on the engine will it be ok and withstand the engine heat?
