OutdoorKing Repair Forum Forums Finding and Swapping Rare Finds & Donations Scott Bonnar Greenkeeper

I had this mower dropped off to me on Thursday and really don't know much about them.Also I really don't know whether it's worth fixing or not.If anyone can help me to decide then that would be great.
Here's what it looks like.


I have no air box cover.

I also don't have the catcher.



So keep in mind I don't have a catcher or air box cover,then is it worth it?
Also what kind of engine has it got? I've never had this kind of engine before.
If I did fix it up what's it worth?

I see alot of these on ebay some in good condition an some not going. But on average I seen them go for 80-150. Its a bummer about no catcher

So cleaned up with catcher I guess I could still get around the 160 mark? I would only have the problem of a catcher.Don't even know what they look like.

it looks a lot like one of the chinese copys though ? maybe a honda cover will fit as it worked for me more than once . they seem to get kicked for some reason ? a catcher i wouldnt know , someone should , seen a few of them around down this end of the place

Is this the engine that is nicknamed chonda? As it does look a little bit like a Honda engine.If somebody has a picture of a catcher that they can put up please? As I'm doing a hard-rubbish run tomorrow and I may see one,but won't know what I'm looking at.

Have not seen this engine before yet. Seems to be a mix of a Honda gxv140 and rover Chinese (Honda copy) engine.

That ones on ebay for 200

chonda it is yes , i think they mostly changed cover and tanks . the same engine on bigw and bunnings type's (cheapies). newer ones seem a little better than they were though only problems i've seen lately are the starter rope breaking and throttle control worries

I'm not even sure what's wrong with it.It's full of fuel and it worries me,as he said he started to try and fix it them remembered he doesn't know anything about mowers.

The chondas I have repaired recently have not be activating the choke correctly, due to the poor throttle linkage design. They can be very hard to start of not choked correctly cold. Otherwise, they seem to run OK.

Is there some documents on how they go together? So I know what I'm looking at before I have a look.

Blumby, just "poke" around the choke setup, remove the throttle cable and and engage throttle assemby by hand, that way you'll get an idea of what needs to be tweaked in or out in order to make the choke engage on full throttle. Like rusty ute said, with these it's more often than not a choke issue and a carby clean at worst.
Have a go, they're not that hard! As for a service manual, good luck with that, they don't exist, from what i'm led to believe.
As for the catcher, when you see one you'll know, they're pretty unique because the 2 halves that join to make the cather are not your traditional "top and bottom style catchers, but the 2 halves come as a left and right setup. So in effect the catcher is joined in the middle. I'll try and get a closeup pic out to you over the weekend.

Have a look in tip and kerbside finds/$20 from the tip, I put a post in there as the one I got was nearly new and just had bent throttle linkages and a quick clean of the carb, still got it and it runs sweet, must get around to selling a few.

Hi Guys, what I'd like to know is where they dragged up the name Scott Bonnar....I thought that stopped with Rover... Who manufactured this machine? Is it a Rover?

Yes its rover still selling them as a bonnar :-) cause there are rovers mowers exact same just red :-)

usually the choke arm is bent making it not choke and a bitch to start and the carbys need cleaning even if they are chondas they do do a good job saying that if u are gonna get rid of it lem me know i have the same rover one here with catcher runs but missing the top starter and covers text me if your interested in getting rid of it

I'll see if I can find a catcher first.If I can well I'll give it a go as I haven't had a go at these engines yet.I really like to know more about them.

ok catcher also looks like a normal rover catcher with a smaller opeinng

I think the catcher is very differnt to a normal rover catcher, they ran with this style for a couple of years before changing it again. The easiest wat to tell is open the back flap and take some pics of the opening, top to bottom.
Here's a few pics of one of mine





You'll note there's no "tongue" on the catcher, it hangs over 2 hooks which are under the rear flap attached to the deck, they are about an inch off the top on either side. If they're not here then it takes a bag catcher, identical a rover 460, which hangs off the outsides of the rear door rod.
