Don't think they were much chop MF. Another I saw was bolted through an alloy honda deck - could see that ending in tears

I have toyed with the idea of attaching a push aerator onto a mower, but it wouldn't work that well.

Have made a scarfier out of a sprinter though - best thing to do with the sprinter. Plus it has a 450 briggs on it, so I don't mind hammering it haha
