Board sweep

Can you have too much "sweep" with a match plough? I assume as long as the tyre can still fit in the furrow then that is all that matters? I have seen peeps running low tyre pressures and seem to use the "bulge" in the tyre to push the last furrow up tighter.
I have messed about with spacers at the top of the board thereby changing the angle of the board relative to vertical with some quite interesting results but when ploughing out some game cover plots a month ago, I used a ratchet strap to pull one board back as much as I dared (didn't want to break it!) and the soil fairly rolled of it, really nicely.
It is a Fergie plough so we are somewhat limited by how much we can pull them back but I have found a way (I think) to pull them back a fair bit more (1-2" to potentially give a 10" furrow bottom compared to quite a bit more on a standard plough)
Would firmness be affected? My thinking is that it wouldn't as long as the furrows matched and not paired and potentially less "break up" of the soil would one hopes improve it slightly.
Just wanted to hear any thoughts before I strip it down and have a fiddle and seeing as this section is so quiet of late!!!

If your tyre as much as rubs the back of a furrow slice, a good judge can tell, all he needs to do is walk on the front furrows, they fall in and away go your firmness points.In heavy land, the touched furrow will stand up a little and wave to the judges, so away go the uniformaty points!

I run my YLs at 11", bottom rear of board to face of the rear landside. I also use 10" tyres on my tractor which give a bit of wriggle room.

When I bought my TS 59 it was set to 13'' from bottom back off board to landslide and pushed the slice so far it was breaking up and not looking uniform ! I now have it set to as said above 11'' ish to much better results .The slice isn't pushed so far and is merely turned over instead off trying to ride up the furrow before it.

Hope this helps

Too much information. I have ploughed almost exclusively with Ransomes - albeit different bodies - TCN, YL, EPIC, RWM and RND. the logic I was always taught and have proved time and time again was ‘put the front board on at rest and then give the adjuster 2 flats pressure, then adjust the back board for parallel’ I would say that in my experience the general purpose bodies are more tolerant than the semi diggers (in the vintage classes) especially for Ransomes boards.
Generally speaking as you push a board out you are also twisting it, which in turn puts more pressure on the furrow in a 3 dimensional way. This in turn can be counter productive to penetration, straightness and maintaining constant depth. As ever, speed is critical.
I always push the back board out 5 flats for the last 2 runs of the finish, sometimes the front board out 3 or 4 flats for the start. Only push the back board out 4 flats for the very last run on grass or you will end up with a high show furrow and a step. Remember to put it back for the opening at the next match.
As said on here earlier, the main thing to be careful of is that your tyre fits in the hole and does not tread on the back of the last open furrow.
Hope this helps.
