Hi Wayne, yes I feel much more comfortable in the knowledge that you aren't going to chop up either of those Greenies that are in surprisingly good condition, they have years of good working life left in them. Much happier to see you have a play with the Tractor and for $25 you could never go wrong. Only big issue with these Greenies is getting the rear wheels off. On a Tractor once I had to eventually cut the rear axle out of the chassis so I could get the axle in my press to get them off. I think in the end it took me a couple of days to achieve it. Probably one of the worst feature on a Greenie. The ones with the bolt on wheels means you can remove the wheel and then get a puller onto the wheel boss to get it off
