I just bought a 2ndhand ride on mower. A Rover. It was red. I tested it before buying it and had a knowledgable person look at it with me. No probs. Got it today. Mowed a lot of my lawn with it. No problems. After around an hour of mowing, it started popping, sort of like it was running out of petrol. I went to put it away in the shed. Just before I got it in there, it stopped completely and there was a quite loud pop/bang.
There’s still plenty of fuel. The fuel filter is new. The battery is good. It starts 1st time every time and doesn’t blow any smoke.
What might the pop/bang be? Something to do with spark plugs? I’m a little clueless. Wanting to learn.November 30, 2012 at 8:11 pm #529306
well you could try spark plugs? is it twin cylinder or the like?
might be interferrance in the timing maybe the flywheel key could need replacement doesn’t take much of a mark on them to cause and issue. seems like a hot problem so maybe a plug? or 2?
next guess a bit of muck in the carby?
is it a rancher?

It’s a lawn king. Twin cylinder? Hmmm. No idea!November 30, 2012 at 8:30 pm #529308
I’m far from a lawnmower guru, but ours does that when I fill the fuel tank too high, it only likes to be up to the half way point some reason (7 year old Husqvarna)…no idea why, but I go with it’s flow. Also does it occasionally if the other half has tipped it over to fiddle with something underneath and then it’s righted and sits for a bit…again, no idea why…damn loud but.November 30, 2012 at 8:41 pm #529309

Oh, now that’s interesting. I definitely filled mine close to the top. Perhaps that’s it. Only thing is I mowed with it for a good half hour after filling it and before it started doing it. It would be nice if that’s all it is. But never ever goes that easy for us!November 30, 2012 at 8:57 pm #529310
Nah, I’m sure mine has done that if I turned it off after mowing that long to go in for a cuppa or something, though don’t quote me…fingers crossed, think positive…DH normally just says the worst that’ll do is cause me to have a heart attack hahahaha…ever the optimist. Think overfilling the oil might do it too…can’t remember, I just try never to do either anymore…especially the oil…everywhere is an understatement 🙂November 30, 2012 at 10:15 pm #529311
hmmm yeh an upmarket rancher by the looks but anyway interesting link:
mmm bloke above not imprssed and never wise to buy any machinery from retailers.
realy can’t suggest anything but the fullness or otherwise of a fuel tank should not affect the efficient operation of any machine, they are only gravity feed tanks.

Yes. The rancher is the entry level. the lawn king is the top-line level.
I also can’t see that a too-full fuel tank would do it but I’m willing to consider it if no-one else has any advice.December 1, 2012 at 10:46 am #529313
yep try all you never know waht may work, the last twin cylinder i had experience with wa the victa 2 stroke twin what a waste of time it was, one cylider would stop working as the reed valve system that fed fuel to each bore was useless. so not sure how they distribute fuel between the bores of 2cyl’ 4 strokes? can’t imagine they would have a proper manifold like a car, with electric fuel pump, no pressurised fuel tank as such.
for me a mower with a 30″ cutter deck worked very well with 7hp, 8hp and 10hp motors that was rancher seems a waste of effort a 20hp twin on a 30″ cutter deck, not keen on toe heal drives the rancher did have a 6 speed gear box and diff. nice and simple and reliable. 30″ deck should have been 40+” cut. and overhead valve not as simple as side valve conviguration as before.
anyhow here’s hoping you get solution. do google on that briggs and stratton engine for tech’ help.
dunno what we might buy if we can ever afford a rider mower? check out snapper maybe maybe a ZTR type machine, no more interest in rover since they went off shore. used to be one of the best.

Well, this machine is 10 years old (so probably made when rover was still Ausse) and has had only 1 owner from new. He looked after it fastidiously and it’s in great nick. No bumps, dents etc, or tell-tale signs of problems. It has 38″ cut and a hydrostatic drive. It runs on unleaded, not 2-stroke. The blades could do with a replace but even as I looked out this morning the lawn looked beautful where I did cut it. I’m thinking maybe spark plug. I might go and try running it again today and report back if it blows up… :blink:December 1, 2012 at 1:06 pm #529315
i know it doesn’t run on 2 stroke i didn’t say any different.
well at 10 years it may need a tweek here or there, rover been off shore for quiet a while now, i don’t run a mental record just awareness for when others seek advice.
so did you do a search for tech’ help B&S have good schematics/service manuals online, you may even find a B&S forum they are good help may even be one, more specific to your exact motor.
that is why i would probably research imported top quality machines, our local one are greenfield and cox. but would go online and see what others are saying first. that rove on e-bay did i see $1800 that is a lot of stouch for a second hand mower.
also been thinking maybe just maybe if 20hp is needed then a 20hp tractor with deck under, at least it will have PTO be able to tow a trailer loaded, use a rear bucket with it lots of versatility and being a diesel will be super long lasting and reliable, just thinking out loud. we had a 40hp bolens/iseke, isuzu motor neat little machine did everything and more.
had a lot to do with snapper in the past then they were a great machine.
keep us informed, probably not teh plugs; replace one replace 2.

I have a red rover rancher which i bought in 2001′ it has an annual trip to the mechanic and has never given a moments trouble but i do remember sometimes it popped like a gunshot when i just turned off the engine without moving the throttle lever to slow first. I think it popped if i started it up again shortly after. I now make sure the throttle lever is down before i switch off. I just had a look at the owners manual and certainly spark plug features in a lot of the ‘possible causes for losing power (also carburettor incorrectly adjusted, air cleaner dirty, dirt or water in oil).
If it is a rover rancher selector drive and you want a copy of the troubleshooting section let me know and i will
Send a copy.December 2, 2012 at 8:59 pm #529317
Thanks muster. It sounds like maybe I bumped the throttle or something. I started it yesterday and it sounded fine. I’ll post back if it plays up again.December 8, 2012 at 11:56 am #529318
Check the quality of the oil as well, oil can degrade to a point where its full of metal shavings etc…it probably wont cause the popping etc but it will blow smoke and run sluggishly.December 10, 2012 at 11:25 pm #529319
All I know is DON’T back over a mower in a one tone ute with a full fire fighting tank on board!!!
