Thanks Eric. Ive also bought a second hand Grillo Climber 9.22. My thinking was this had the largest engine without being 4WD. 4WD would have been nice, but these are more expensive and there are more parts to go wrong. I havn't felt I have needed the extra traction in the past, but maybe I will regret this. For some reason the tyres have been shifted from tractor tyres to turf tyres, so I will probably return it to aggressive tractor tyres that will help with the traction. Regarding your electrical issues, you might try a 'contact spray' to control the oxidization - the kind that you use to protect trailer electrics? Alternatively I have bypassed all the safety systems in various mowers. I haven't looked at the Grillo's electrics yet, but normally you have one circuit running to the ignition key that needs to be closed by the various safety switches to work. Normally the safety circuit is a different colour from the black/red of the earth/positive - yellow or blue. A bit of continuity testing with an electrical tester will normally work this out. Let me know if you want me to figure out how the safety switches work on mine?

Thanks. Yes the others have newer B&S engines which I understand are not perfect. Brushcutters or rough cut mowers have thicker blades, off road tyres, do not collect and are generally built to take more abuse.

Does that brass metal vent thing work? meaning does it allow air in and stop (too much) fuel escaping. It depends how precious you want to be, but its just an air vent, you could try gluing that fibrous thing back in. Clean everything with narrow wire and carb cleaner.

I have but the thing is I wouldn't use it "for anything else" just mowing.

Castle no. Its an old market garden, where they used to sell plants, fruit and veg. Flat varied ground but very fertile alluvial soil so the grass and weeds grow like stink. I also do paid work for a few people who can no longer maintain their gardens or use a chainsaw - so think of knee high grass with buried obstacles. I like fixing older machines and keeping them going.

So my ancient Bolens ride on has finally had to be retired with a cloud of issues - camshaft, gasket leaks, clutch, rust, broken spindles. I am looking for people's experience with the various ride on brushcutters out there. They all seam remarkably similar. Generally I am looking at the model with the largest engine in the range that is not 4WD. I could get 4WD if second hand, but the new 4WD ones seem to be more expensive. On the face of it 4WD would mean a few more parts to go wrong. - Orec Rabbit RM952 - Grillo Climber 9.22 - Etesia Attila 98 Budget of £5k if second hand. The new ones are about £10k. I'm not adverse to new either. And before anyone else suggests alternatives, I have an ATV flail mower for the really rough stuff, 50cc strimmer and a normal collecting rotary mower for lawns. This is for quite specific applications, tight access and under orchard trees. Thanks in advance.

Purge bulbs can look bad from the outside, but inside they are fine. I'd just disconnect the pipe that returns to the carb and pump fuel through it for a while. Then run. Check everything for cracks and air leaks.

Purge bulbs are pretty easy to replace, just make sure you get the lines back in the right order. Regarding the bar oil leak, to see if all parts are there, you are best to check the assembly diagram online for your model of saw. Also get the saw and bar spotlessly clean and check that the face plate is flat and sealing properly. Confirm its the right type of bar and correct number of chain links for the bar. Also check that the bar oil holes line up - a good technique is to make paper or cardboard copies of the bar

Sorry I am not quite sure what you have replaced already? Have you bought OEM part number 1129 350 5850 "Tank Vent for Stihl 020T, 020" (photo below)? Buy this and everything should become clear. This part comes as three separate parts, which get combined and fitted together. Your top photo looks like the middle metal part of 1129 350 585. Your next photo looks like the innards for the plastic part on the left of the photo for 1129 350 585.

As above, flush out the tank a few times, pump the purge bulb if there is one and run it until the smoke clears. Then Id maybe check the plug is clean.

Thant will definitely help. I tested that with a temporary ethernet cable first - you can also get flat cables that are easier to fit under closed windows and doors etc. The temporary cable worked fine for ages, but I did eventually dig permanent cables round the house and drilled through the walls.

Thanks for the warning! I'll find a way to do this safely with the blade on. Yes I think that's all ok Pinions clean and lubed up. The cable is free and engaging the drive. What's odd is that one wheel drives and one doesn't. When I say one wheel doesn't work, this is even if you lift the mower off the ground. The one that works appears to have most wear to the pinions. Does each side of the gearbox work independently or is it a solid axle all the way across?

Personally I don't think its tuning. I wouldn't have thought the high jet had anything to do with starting, that's just for peak revs and your approach to low jet tuning seems fine. Its just vapour lock or fuel getting hot and bunging up the carb. I don't have any magic soluiton. Keep fuel in a cool place or out of the shade. Open the fuel cap and pour out any remaining fuel before starting. Put saw in the shade for a few mins. Take a break and sharpen your saw.

Thanks. I was thinking of doing more something along that lines - more comprehensive diagnosis and getting closer to the drive. For safety, I was thinking of taking the blade off and raising the mower up on a fish crate or something similar. I could even turn the belt by hand with the engine off.

Its a shame redline is about five times the price of most other decent oils ! Anyway I need to do some research on this stuff. Thanks

Same. Neat petrol goes in either jerry cans or rectangular 5l petrol cans. Mix goes into either the combi can or reused aspen bottles for the strimmer.

Ive been using red Oregon two stroke oil for the last three years at 40:1. No engine failures yet! Please note I havn't taken any apart any engines that have used it, which would be the best way to confirm its quality and check the big end, however I've inspected several pistons with a torch and they look good.

Its still nonsense to me. The Stage 1 report identified a roof (with gaps under the eves and missing slates) and attic space and said that theoretically this could be used by bats. Nothing earth shattering here - Any roof build before about 1970 won't be particularly airtight. I guess what I am trying to say is that in most other professions, there are situations where a stage 1 can be carried out (on a low cost or desktop basis) and there is no need for a stage 2. For old roofs, it seemed like stage 2 will always be required. It frustrated me that this wasn't made clear. The whole process needs a shake up and a cost reduction. Or use of CCTV or recording devices that don't require people to count bats manually all night.

@pleasant So a wee update. I got the drive pinions off and both of them were moving freely. The internal parts for the wheel that is working are a bit worn, so they may need replaced in time. Behind the wheel that wasn't working, there were two problems. This plastic spacer is cracked, but I'm not sure that is causing any issues yet, its more to do with raising and lowering the height of the machine. Maybe I can glue it. Secondly the retaining wheel nut was stripped (not shown in these photos). I suspect this was preventing the large cog in the wheel from aligning with the pinion gear. I repaired the thread, but still no drive on that wheel! The investigation continues, maybe something wrong with the gearbox.

Yes, it would be logical that the fence was constructed on the boundary and the hedge grew up around it, but who knows.

Bat surveys make me so angry. I commissioned a stage 1 bat survey once. They couldn't find evidence of bats, BUT nor could they prove there weren't bats - answer stage 2 survey and more cost. I gave up and let the building's roof fall down naturally. What's the point of having a stage 1 survey if it leads to stage 2?

Its not as straight forward as 'who owns the hedge.' What you need to establish is where is the land boundary between your land and your neighbours. You can download a title plan from the land registry. You can do what you like with a hedge growing on your land or branches of a hedge going over your land.

I generally move bags on the loader, but when I have used a trailer, I ratcheted down a small section of ladder that I have lying around.

Just be aware permethrin is also highly toxic to insects and pollinators. Dogs shouldn't be allowed to swim nor run through thick cover for 2 days after treatment.

I only use bio oil near watercourses, as thats what is required by law. Its a shame all bio oils seem to bung up the tank and lines. My general response to poor oil is to dilute it with diesel, but this would rather defeat the object!
