Thanks for this – I’ll give the plate a fettle at the weekend. I have now welded up the front frame tensioning plate, and I have also found some nos bearings for the front wheels which were in a right state/ missing. The rear height adjusting wing nut and collar are missing, so I’ve bored out a hex nut to slip over the 1/2 adjusting screw stud and…[Read more]

Thanks for your attention. Photos attached. All the blades swing from side to side, but they all foul on the plate because it is not flat, and so will not swing 360′. I wonder if I am overthinking this, and just a bit of deflection is all that is needed.
I checked the gearbox this morning, and it is good for oil.
I went to tension the drive…[Read more]

Can anyone advise on replacing the blades – I’ve got a new set. If I snug the bolt for each blade down, the knives will not rotate due to the aluminium plate not being flat. So I guess I need to fettle/flatten the dish locally so the knives do rotate when the bolts are tight – is that right?

So I fitted new points and condenser (I did eventually buy the funky little tool to compress the spring as I found that a bit of a fiddle without, and the wire from the coil is getting shorter where the spring cuts into it), I changed the carb diaphragm and put in a new plug, and bought a new air filter as the old one had disintegrated, and then…[Read more]

Thanks for response Andy. So with a squirt of some penetrating oil, a good torch and more perseverance, I’m very happy to say both valves are in fact moving. I put a compression gauge on the engine and after a few pulls can get to 80 psi. So a much better starting point.
I’ll try to get a spark, check the coil, and if necessary pull the fly whe…[Read more] -

Hello people.
A first poster here.
I took a punt on a spares/repair 1975 Hayter 21 with B & S 5hp engine, a couple of months ago, and have the time now to give it some attention and hopefully get up and running to cut the grass on a small holding I own.
The good points are that the machine is complete and although it looks well used, the overall…[Read more]
