the worst problem with a cyclo planter is that they could do a passable job when entirely worn out.   and believe you me it's pretty hard to hold my tongue when somebody was complaining about their cyclo planter performance, when it was known for a fact that there wasn't a dime spent on it in the last 3-5 years.    seen a lot of things over the years.  holes in seed tubes fixed with tape, opening discs worn beyond worn, busted closing springs not replaced, chains so tight and rusty they'd stand up in the corner, bearings out or going out. there were a couple planters that I know of that the drive shaft  for the herbicide/insecticide boxes, was twisted so bad that they had to replace the shaft and all the bearings together. the owner was at a loss as why this would affect seeding accuracy.
 
   they are a pretty easy planter to operate, but they have to be taken care
