I've done 1150ha with my 3m, then put worn big disc as small disc, new big discs and bearings cost £60.65 each, so £1091.70 to redo the 3 m (18 discs), I had replaced 15 bearings in that time, but I have now got the bearings off the worn small discs to use, so they're negated to a point. My...
The osr volunteers were knee high at drilling time.
Still can't quite believe it.
Wasn't brave enough not to pellet though.
Got mega populations here in every scenario.
Wet summer and Romney marsh equals lots of slugs
Just a slight aside.
Join an organisation like benenden health care trust.
It's not private medical insurance, and they don't do real major stuff.
BUT they have 24 hr GP helplines, mental health too, and if the wait is too long on NHS they can step in and see you privately.
And for an absolute...
I find the biggest issue is speed, followed by the wet soil as @tr250 says above.
But blocked tubes also as the beans can jam, I always insist the seed cleaners dump the biggest beans in the waste, that helps a lot.
Not sure scrapers make much difference, I find it's keeping the discs shimmed...
It gets to the point you can't shim them to touch anymore.
I'm currently using the worn serrated discs as the small disc. I wore it about 5mm too far to be ideal, ( had someone else drilling while I was combining) if you wanted to do this, wear the serrated ones until they're slightly larger...
My advice would be get a sabretine when you sell your kit.
It will allow you to drill in the wet times when the gd isn't able to.
Although the gd will go in conditions that are unbelievable, the tine will produce a better stand in those conditions.
Still no need for the plough here.
