Counter sunk disc bolts

[Howard150]

I disagree on this,its the share that put the shine on the work, not the board,
but it needs a good clean board to keep the shine on the furrow,
as regards to pushing the board out to get more pressure, only works the first time around, after that the furrow bottom is wider, and you can only fill the gap, not get any more pressure is available,
in order to keep the furrow more in one bit, its best to pull the board back as far as you can, but still leave room for the tractor wheel, the less angle of exit from the end of the board will leave the furrow more in 1 bit, the bigger the angle the more shattered the furrow slice will be,

think of it like painting, and think or the board as the thinners, the share, disc and skimmer are the paint,
if the have crap paint it will never look good,
and the thinners are only a way of transporting the paint to a finished surface,
cheap thinners with good paint will look better, than cheap paint and good thinners,
as long as the board does not stick with soil, then its good enough to win with,

90% of the work is done with the point, disc and skim,

cut it out badly, you cannot polish a turd

Apart from in sand this is why the position of the disc is so important. Rear of the point and high forces the share to do more work and this is where the shine comes from. Skimmers as high as possible and forward means the furrow is not disturbed as it starts off along the board.
A wrongly positioned disc side for side not only spoils the coulter face but stops the landside working to full efficiency. Insufficient lead to land on the share has a similar detrimental effect and will make it extremely difficult to go straight, control depth and do the fancy bits in hard ground.
Very significant point here is the transition point twixt share and board. Board too high skims the shine off. Board too low and the build up of soil sticking to the front of the board will ruffle what ends up being the furrow back. Might not look too bad when wet but as both cases in point start to dry they will look powdery, ruffled and dull. Smooth transition is what’s required.
Forward speed has a big bearing on all this. Pushing the boards out and increasing speed will shine and compact wet sand.
No matter how good a ploughman we all think we are - every day is still a school day. It’s not just what we see or read either. Next time you go to a ploughing match make sure you are listening as well. Lots of good off the cuff tips floating about.

this is very true

Pressure on the board should be firm and uniform from front to back. This is enhanced by a slightly backward and shallower disc. The board creates the shine and must do the work so don`t break everything up before it gets its chance.

Not true Bob look at this, all the same settings, same field, just a share change.

Consensus of opinion says I am wrong and stand corrected. Now off to work on the plough!

Same here, though it would be better to be working "with" ,instead of "on" it!
