    Thanks for that @deezell , appreciate the input! I might be able to work a corded electric either. Would that increase my options?


    ETA: <= 34cm should be fine also. The garden may be smaller than 55; that’s just a ballpark. Would something like this Karcher do? Or are there better alternatives in the same price range?

    It would, but they're a pith, you'll cut the cable sooner or later, that's if it doesn't internally fracture from flexing at the entry point, requiring opening up of the cable terminator, cutting back and rewiring. Oddly enough, I had to do this very fiddly repair on a corded electric chainsaw yesterday, which gets reasonable annual use. I've managed over the years not to cut it, but the flexing fractured one conducter at the entry point. Swmbo has cut the cable on her small corded electric hedge trimmer, again requiring terminator point rewiring, jointing not a good idea.

    One of the family uses a 34cm cordless on about 70 m2 rear garden, tears around it, mower is light and handy and can be lifted onto/over other stuff in his tiny shed. You can use the batteries in a matching strimner also. Check out B&Q too, Diy.com

    Ah ok, will stay away from cabled ones in that case. I update my previous post with a link to a potential cordless, but it’s a good shout to look at mower + strimmer combos.

    I’ll have a look on the sites you recommended. Thanks again, appreciate it!



  • Registered Users, Registered Users 2, Paid Member Posts: 8,663 ✭✭✭deezell


    WORX bundle on the same site looks decent, two batteries, always handy to have as you can have one charging.

    Can anyone recommend a petrol walk behind lawnmower for a large garden? I can`t afford a ride-on or robot so was wondering would it be a good alternative to get a large walk behind instead.

    Big cut Small money, the 56cm Proplus is a robust no nonsense machine with an Alloy deck and a big B&S engine, and backed by a proper distributor. This one is €100 less than most other dealers at €599

    With a ride on and standard blades is there any advantage to using a deflector over a mulching plug if not collecting the grass?

    Would you be able to "mulch" (not collect) slightly longer grass with the deflector and have it spread over slightly larger area?



  • Registered Users, Registered Users 2, Paid Member Posts: 8,663 ✭✭✭deezell


    Yes, but it won't be cut finer or forced under the cut surface, and most will sit on top going brown until your next cut, where it will be chopped into unsightly dry fluffy clumps. The only advantage is that the mower won't be as strained as it would attempting to cut and mulch overly long grass with a mulch plugged deck. If grass growth gets ahead of you, you have to bag and remove it until you can resume the shorter frequent mulch cutting intervals. Powerful zero turn mulchers are the best at thrashing overlong growth into pulp, which quickly withers and falls below the cut surface. A deflector tends to create a sward of longer grass sitting on top, like a mini meadow.

    Brilliant. Thanks for that. Makes sense.

    Doing a bit work so no really space to dump the collected grass at the moment so was looking at all options.

    The current weather isn't making frequent mulching cuts easy!



  • Registered Users, Registered Users 2 Posts: 181 ✭✭ppn


    Have had that Stiga and it's a complete dud. The actual hp of the B&S 675 engine is just over 3hp, which makes sense as it cuts like it has 3hp. The mower body has a lot of light plastic, prone to breakage, even the wires for the self propelled mechanism have snapped. Best avoid for anyone looking at this one.

    I'm not sure why you're quoting a post from 19 months ago for a mower that's not available from Doyles and elsewhere anymore, so should be easily avoided. Furthermore, the mower in that post had the Stiga 'own brand' (Loncin) ST170 engine, not the 675Exi, which was available with that Stiga at some earlier stage.

    I know the Loncin ran at 2900 rpm in this Stiga, which rpm would have been on the downward slope of the 675 torque curve. At 2900 the 675 would have produced 3.8hp, at a more credible mid point of 2600, it would output 3.7 hp, so you're not far off quoting 3hp if yours ran at lower rpm. That's real hp, not the nutty peak figures seen in ads. You can look up the Loncin performance if you wish, its a decent economy workhorse. Perhaps for cost or other reasons Stiga stopped using 675. The B&S bankruptcy hiatus in 2020 and subsequent rescue wouldn't have helped, I've heard that some B&S engines now issuing from Pakistan are practically throwaway. Heres the torque/rpm curve for the

    675Exi. Multiply Torque (ft lb) by rpm÷5252 for Hp. Multiply Hp by .746 for Kwh output.

    Lost key for my Viking mt 5112z.

    Does anyone know if uses the same key...thanks!




  • Registered Users, Registered Users 2 Posts: 10,336 ✭✭✭✭The Continental Op


    Thats the most common one. If you have prime get a few https://www.amazon.co.uk/Ignition-Starter-52813000-Compatible-Tractor/dp/B0B9LZK8YP

    Wake me up when it's all over.



  • Registered Users, Registered Users 2, Paid Member Posts: 8,663 ✭✭✭deezell


    Meanwhile, get a bit of flat metal or hammer a soft bent nail flat, or a flat screwdriver. That will turn the ignition, there are no tumblers in those ignition switches.

  • Registered Users, Registered Users 2 Posts: 88 ✭✭redseat1


    Thanks @The Continental Op and @Deez

    Started it with a small screwdriver, and when I was on it I found the key in the garden where I had dropped it when using the push mower around hedges!



  • Registered Users, Registered Users 2 Posts: 10,336 ✭✭✭✭The Continental Op


    On my Honda ride on I keep loosing the petrol cap which comes off when I cut in close to the base of a hedge.

    Wake me up when it's all over.



  • Registered Users, Registered Users 2 Posts: 8 airdog


    i need a gearbox for a honda 536c hydrostatic 21 inch cut just been quoted 1000 euro



  • Registered Users, Registered Users 2, Paid Member Posts: 8,663 ✭✭✭deezell


    Yep, half the price of the mower new. Did the grand include fitting? The same mower with steel deck and single speed drive is... €1000! Brand new. I doubt there's a pattern part available that does the same job. Chances of finding a used one cheap are slim. Perhaps convert it to the manual single speed box, if you can get a used one all the better, get a few more years out of it.

    With till all the electric car owners have to pay half the car new price for a replacement battery after 7-8 years, scrap yards will be busy.

    My Sthil RT 5112 ride on has developed an issue. I was cutting for the first time in 6 weeks and working away for over an hour and suddenly blades stopped. Belts are still tight and nothing blocking the blades but when hit the switch to engage the blades, I hear a click of a relay or solenoid and nothing happens.

    Any ideas?



  • Registered Users, Registered Users 2, Paid Member Posts: 8,663 ✭✭✭deezell


    First check that the deck belt is not broken or thrown off the pulley.

    Check that the grass bag is fully closed and pressing in the interlock switch.

    As you can hear clicking, it sounds like the blade clutch relay switch is attempting to power the clutch solenoid. (on the 5112z, power to the clutch is directly fron the blade switch i think, I'm not sure if there is an intervening relay). You'll need to check that 12v is being supplied to the clutch, or find out where it's going missing. I'm not sure if there is a fuse online with this clutch supply. There may be. You'll need to take a multimeter to it. The grassbag switch generally knocks of the clutch, so that one first.

    its not the grassbag/box switch. I run the mower with a mulch plug kit and dont need the box, so I have the switch ziptied to be always engaged and it still in place.

    Ill have a check of the deck belt next.



  • Registered Users, Registered Users 2, Paid Member Posts: 8,663 ✭✭✭deezell


    2. Heat it before you straighten, then reverse it as per 3. If there's even the smallest crack, angle grind the piece off, repeat for the other two blades. Do it accurately to keep it balanced.



  • Registered Users, Registered Users 2 Posts: 1,159 ✭✭✭Krombopulos Michael


    So checked deck belt. It was still on the pulleys etc but was pretty shredded. Off for replacement. Thanks Deezell



  • Registered Users, Registered Users 2, Paid Member Posts: 5,938 ✭✭✭blackbox


    A

    Bin and replace.

    Why risk injuring someone for the few euro to replace it. These run at high rpm.



  • Registered Users, Registered Users 2, Paid Member Posts: 8,663 ✭✭✭deezell


    If you can get the disk from a proper store, go for it. I dislike those three wing blades, the impact shock alone is fearsome, I'd be more worried it would rip the headstock off the strimmer than bend the blade. Cutting off all three sections and reversing is the safest temporary measure until you get a new one. I'd trust this one from Screwfix, if its a fit. Only a tenner.




  • Registered Users, Registered Users 2 Posts: 89 ✭✭Zverklez


    Any recommendations for a petrol strimmer? I have no idea where to start but it would be a for more than just a small bit of edging on the lawn. I was hoping to keep it under €250 but it seems like €400 is the starting point in local shops for serviceable brands.



  • Registered Users, Registered Users 2 Posts: 9,213 ✭✭✭jmreire


    I would not be too sure about scrap yards being too busy, at least ordinary car scrapyards. EV's require special treatment from day one, so I suppose the end of life EV's will require an even more complicated procedure.( and therefore more expensive )



  • Registered Users, Registered Users 2 Posts: 10,336 ✭✭✭✭The Continental Op




  • Registered Users, Registered Users 2 Posts: 611 ✭✭✭cathy427


    Did you just want something for lawn edging? Sorry just not sure with the way it's worded.

    Apologies for the confusion, I would need it for more heavy-duty work clearing areas out.


    The Titan branded petrol ones in Screwfix appear to be out of stock nationwide. I was looking at a model in Woodies but it appears that there are no spare parts available for them when they go wrong or need a service.
