I like the last! Get a mate to go and pick up a handful of straw from all the other plots, telling the organisers that he was asked to do it,(but not by yourself) and your the only competitor!Point taken Tony. Been ploughing a lot longer than you and it was always taken as read that you were not allowed to clear straw once ploughing had commenced, even as late as 2007.
The new Scottish rulebook says only the competitor is allowed to clear the plot of straw and stones. There is no qualifying time period.
Again in the rules for Southern Ireland straw or loose objects may be removed but the raking of stubble is not permitted. Working on a plot before the competition commences by either the competitor or someone working on his behalf will result in the competitor being eliminated from the completion.
Joking aside, Straw stones etc have been fair game for removal at any time down here. My first national was in 1979, dont know how that scores in the age stakes!
