Can't help you here but maybe count your blessings it is only barley and etc! Just down the road from us, quite a few years ago, a local lad plugged the walkers of his machine with safflower. Safflower, an oilseed, is a member of the thistle family and is so well endowed with spikes that a couple of seeder widths around a crop has been used to keep wild pigs [ hogs ] out of a crop that the pigs were partial to. The local lad spent a couple of days and a large number of leather gloves while lying in the back of his machine, unplugging the walkers with a set of pliers! No transcript was kept of his utterances during the unplugging process!
