We recently put on a set on our 30' 1020. We haven't used them yet but there was a post about a month ago on AgOnline and 2 or 3 guys that had used them said they were satisfied with them. Didn't see any negative responses about them. Yes, the drill bit furnished is too large, you need to use one about 1_16" smaller. They mount one grabber between each roll of the flight and are spaced every 45 and should start so that the 1st one one the end is between the flighting and the end of the platform. They do not stickout quite as far as the flighting but fairly close. I have questions about wrapping as well but I figured at $225 for a 30' head they were cheaper than a full fingered auger and worth a shot. Have spent more money one things that were a bust in the past and if the money breaks me I should have gotten out of farming sooner. On the 30' they sent 10 grabbers. We added the auger extensions to our platform and to get the grabbers to workout right we had to purchase 2 more.
