OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Gidday, new member with a Scott Bonnar & question

Gidday, I love this site. I have just bought a Scott Bonnar reel mower Model 45 series, 14" cut & even came with the original Instruction Book & Operating & Maintenance Instructions book & Warranty Card(Purchased 02/10/78).....I am willing to share with members/photocopy it & mail it out or if I can(doubt it),scan them & put them on the site. Might have to get kids to help me. Had been in a shed for 6 years, just degreased it/cleaned it up but the green round cylinder on the clutch shaft is broken I have looked at all the bolts etc but I would rather have your expert help in advising me how to remove it so I don't bugger it up or unnecessarily undoing things I don't have to.
Regards & thanks
Ian

Birky,

The easiest way that I would remove the clutch system would be to undo the three screws on the outer cone assy (one near the chain side). Then remove the four engine mount bolts (holding engine to frame) and remove the engine with the inner clutch housing.

The rest is quite simple.

Birky,
A big warm welcome to the site, you will find us all a friendly bunch here; we like to learn new skills and tinker with all things reciprocating.....and in my case, all things Scott Bonnar.
I have just done a clutch restoration on my Model 45,and as Bruce has said, it is quite straightforward once the motor is off the frame.You may like to take advantage of the Parts and Manuals topic on the forum.To access, you make a Paypal donation....Just press the top button at the very top of the page....the manual will guide you thru it and supply part numbers should you require replacement parts; Bruce will advise on supply.. ....Good to know another Scotty afficiando...Again welcome,
Kindest Regards, Darryl

Birky, just a thought, you may like to see some pics of my Model 45,with reconditioned clutch assy, just scroll down to page 1 "old Mower Pictures" topic further down on this forum. It's not completely original; I had 2 problems with it ; one was called "Briggs" and the other called "Stratton"
Viva la Honda!!
Kindest Regards, Darryl

Hi Bruce & Darryl thank you so much for the welcome. As I'm getting on in age(as my kids tell me-46 is old) I have a real interest in small mower engines so I am really looking forward to tinkering & reading/using your vast experience to assist me along the way. Darryl, yep I had a look at your Model 45....WOW...that is a credit to you, excellent job...had a laugh about the '2' problems. Have you guys heard of the 'Falcon' brand of whipper snipper? I actually had one, bought it off a mate who imported them in 1985 to do my 2 acre bit of land. It lasted me exactly 20 years, 5 months with regular use before it was not worth repairing. In all that time I only replaced the cord head & spark plug once. Just goes to show if you look after your gear, it will last. Once again, thanks for the welcome & I will be a regular reader...there is so much info on this wonderful site. Paypal donation on way.
Kind regards
Ian

Hi Ian,
Thanks mate for the kind comments,Wow,you sure had a good life outta the Falcon, and yes it does certainly reinforce good maintenance will reward you with long service.
Once again, best of luck with your Scotty, and welcome aboard!!
Kindest Regards, Darryl

Hi Birky,
I know it's almost a year gone since you posted this article , but I've just met & fallen in love with a model 45 / 14 inch Scott Bonnar myself. The cutting blade cylinder is down to it's last possible adjustment and I think I'll need to find a replacement one. I'd be most grateful for that manual if you're able to supply me with a copy somehow .Cheers

You should have found the parts manual in the parts list and manuals area. If you can not find what you are looking for just post a request and we will get it uploaded if we have it on hand.

I have the last (that I know of) catcher for the 14" New as to the cylinder that can be re bladed without out too much trouble.

As this thread has not been in use, I will now close it.
