keep an eye out for bits/non-running mower on ebay/auctions?
Can you bolt a trunion on and then put a threaded pin through that and hold it to the trunion with some bolts?

sounds an odd failing
I think you should re-engineer it and make up some cardan shafts, a power take-off, and some bevel gears so you can power the seat roller too. That might lessen the load on the pin.

Heh at powered trailer. naughty thought.

Failing due to metal fatigue on a weld joint holding a washer in position around it - the crack is exactly there - and it occurred when the seat went over a brick path and cracked the pin when it jolted.

886 on this, the pin into which 509, 506, 502 fit as it has a thread in the top to hold it in place. The whole frame round the roller is 886. The pin has snapped just underneath 885.

The sad answer is drill out the stub of the pin and find a much harder steel bolt with a thread running from top all the way to the bottom. Hold that in place with a big washer and nut so it is flush to the box frame above the roller then put some steel tube over the thread as a sleeve, leaving some thread poking out at the top, fill the tube with grease to allow movement, insert the rest of the frame over that replacement pin and pop another washer and nut on top to hold it in place.

But where is the fun in that.

Option B would be to stick shock absorber and road spring in between the roller and seat.

the ebay point is good. when pater got a new sit on mower he kept the old one as a workhorse, took the blade section off, which my sis flogged on ebay

I don't know buzz, I didn't expect... *gets squashed by large animated foot*

interesting botters, that wasn't the pin I was expecting. I reckon harder isn't better here. some give would be useful here. I like the idea of a shock absorber. you could put a new one in the pan and use that..,

ebay has a selection of aspirationally priced items, as these are now quite collectible (don't ask me why, but they seem to be the best for cutting tennis courts, croquet lawns etc). They are whole items and therefore v heavy and collect only. from places like Durham and Galloway. No. I'd prefer the part or to fix it.

The thing about that pin is that the roller pivots on it. So not sure a hard steel bolt is the answer. It needs a smooth, greased, pin in there.
Back to the welding theory.

I actually may do that Chambo when my Mountfield ride-on stops being good for cutting but still has working engine and transmission. Then the grass hopper comes off and a massive supercharger gets bolted on.

I have too many of these things. Just realised.

I wouldn't turbo or nitrous it. most racing doesn't like that (unless you are dragging/sprinting).free-breathing exhaust, bigger air intake, bit of head work, advance the timing, thinner head gasket and lighten the moving parts.

Actually mutters, what you should do is convert it to run on ethanol and brew it yourself (either from wood or for when the homebrew goes a bit worng).

After all manufacture and storage of a flammable substance (which burns with an invisible flame) sounds just what you need on the premises, it doesn't sound nearly dangerous enough at the moment...

well neither of your links actually helped because the actual part to search is auto-steer seat which is not listed as an ATCO Royale 24 specific part but an additional item for all Atcos so you both were entirely useless. so carry on.



invisible flame, you say? Mmmm liking that thought. Taladega Nights etc.

Right
Here is an update on things for the mechanically minded.

The tractor is fully mended. Got up early on Sat and got on with it after the breakfast of kings: five sausages and two eggs, coffee, orange juice and toast...leaving five sausages from the pack of 10 for eating cold. Later, when I came back in the house I discovered the had helped herself. She, like me, has a cold sausages issue. Neither of us can block the urge. I have her a sympathetic but disappointed look as she hung her head with resignation to her dependency.

Getting the broken axle pieces out and then new one into position was easy enough but then then the issue of fitting it up. It lifts the cutting deck so is wishbone shaped and has to swing on two pivots points. Do you fit it to the deck then lift the whole thing with a jack to attach the pivot points (no) or so you fix the pivots and then lift deck on a jack to attach the six points of connection between axle and deck? (Also no, it turns out).

Both options means there is no space to attach and turn a socket between the two parts or that the axle won't marry up to the right pivot points as the deck, even jacked up, pulls it away (the deck assembly goes down and forward to drop so the linkage arms want to push the axle away from its bed. Of course it was never going to be as easy as planned.
The answer on attempt three was to half fit the pivots, one side then other then one side then other, painstakingly, with just a few turns of their bolts then connect links then tighten into place jacking a centimetre each few cranks of the ratchet. Not much room to manoeuvre.
2.5 hours work.
Then i tried it and discovered I had overtightened the joints and it was stuck up or stuck down and unhappy lifting itself. Cue loosening and lubricants. Now we are back in play.

Next the seat for the other one - easy

Then the Pan- rear brake calliper refurb. Gets a bit sticky.
Then the son's bike (junk, I may buy something more fun and tool it up and turn the mini bike into something crazy.

A good and productive weekend.
I spend Sat am using a garden shredder.
During the minicam's nap-time I investigated why the paper shredder had given up. It had completely stripped a pinion (also appears to have been greased liberally with what appears to be earwax. Funny peeps the Chinese...).

The pinion was a bit odd. Rather than making a gear on a shaft, they had cut the entire length of the shaft as the pinion and then forced into the nylon gear on the same axle. Pressed that out with the aid of a vice and an old socket, and turned it round and put it together with copious amounts of araldite. Will reassemble and see what happens. Anyone know where I can get some ear-wax to complete the assembly?

Decided I couldn't do a pint now but I could do a bit of idle engineering porn. And here it is.
These vids make me smile. Particular heh at three bits

1) the Wankel rotary engine clearly taken off some huge heavy iron WW2 fighter on the back of a VW Beetle. Heh.
2) The chicken versus the turbo jet. Roast chicken anyone?
3) the guys firing up that twin on casters. Bunsenburnertastic. Then silence and a heheheheh afterwards.

I love the aero engine start up in the aircraft museum. A real face on that chap. Yeah, he's saying, that's workin'.

Right, same thread, new issue.


My mum has in her barn the mother of all petrol rotovators. It is like some Stakhanovite coal mining relic. A massive Briggs and Stratton four stroke engine which takes the strength of a bull to pull start atop a sort of plough frame with four flailing blades at the bottom on a shaft with no protection whatsoever.

It's like this only much larger. You can only just lift it and move it around. Once it gets started it rages through the clod like something from Journey to the Centre of the Earth and it bucks and shies like an angry mustang. I reckon it could easily dislocate a shoulder or mince a human being if he was run over by it.

I'm putting a "mine" sticker on it and will revert with refitting updates. ANOTHER ENGINE.
