during the harvest it's quite easy to clean the front section, but we were going to remove the rest for winter clean_maintenance, true it would be easier to clean if it was a NH as there would be no dividers on it but I wouldn't expect any combine to have a clean grain pan under the conditions we have to work with (25-30%mc, green straw, stones, soil, laid crops, grain growing in the ear, I could go on but I think you get the picture that it's not easy in Scotland). And anyway I've got around the problem by delegating someone else to crawl in and steam clean the rear section, hahahaha, and it was only -3C that night.
