I have a Ryan Lawnaire v aerator that I purchased back in 2003. I've used this aerator for years and have had no problems until this last year or so. I noticed in the fall of 2010 that my plugs weren't as big as they have been in the past so I figured it was time to change the spoons. I ordered a new set last spring and replaced all the spoons on the machine. The new ones did look longer than what was on the machine so I figured the plug issue was from the wear on the spoons. But, I still had that problem of small plugs during last year's aerations. I am stumped as to why this machine isn't pulling big plugs anymore. I have noticed that I've had a problems with the spoons getting clogged up so that they aren't actually pulling a full plug length, only maybe 1/3 to 1/2 of the spoon length. I can't figure this one out at all, and it's very frustrating. Anyone have any suggestions or tips? I'd really like to just fix this aerator and get it to work good, it's still in great shape and it's made me a lot of $$ over the years.
