Drum mower problem

[devonbeef]

Having a pain ii the behind problem with 2 drum mower, The saucer bolts keep on coming loose, put thread lock on them, torqued them up tight, had them tight before i started ,as had put new bearings in hub. Mowing today 2 acres later, looked under to check,as thought it would be a good idea, as only just done repairs, Bolts had come loose on 2 ,and 3rd one missing.
Found another bolt and tighten all up again , then mowed acre of grass ,looked under all loose again and one missing, bearings all tight, no noises,
Out of bolts now and going on with another mower i have, but at a loss with reasoning for them coming undone,
Was thinking some ptfe tape with thread lock on bolts i have ordered , not got much confidence in this being much better.
Any body got any ideas /solutions ? cheers DB

Tack them with a welder

Tack them with the welder once tight. Sometimes is wriggling to make them come loose.
Got beaten to it by the looks of it. Welder.

Now Then..
What make of mower is it??
Generally a new hub, saucer and 3 screws should cure it..
Take a look in the bottom of the current saucer first. There may be something like a bit of bearing in there. You think the screws are tight. However, yes, they may be tight, but if there's something in between the saucer & the hub, they'll be loose in a flash, eh..

its a sip rota165 , quite worn, had it since new done several 1000 acres, new bearings, shaft to seat bearings are worn, so they do not fit perfectly , but not terrible, have chipped them a bit to make bearings tighter on shafts, sounds healthy that is what is annoying, that to be honest might be the problem, stuff in saucer where hub slides in, i think a good clean out there first, thank you, see what happens then, leave welder for a bit i think

several 1000 acres is not true , it would be more like around 1000 acres total,
