The last item oldest daughter is very interested in because she grows for her road side stand and has four restaurants that she supplies in the summer.
Being young she has no trouble getting up and down but time is her issue.
Well now I’m confused. Maybe one of my pics isn’t showing for you. The third item has the red seat and wide plastic wheels and is not a kneeler. Green thing with woman holding a plant in a pot is the kneeler. Fourth one.
By last item, do you mean the paperpot transplanter? That’s the last pic. It’s a worthwhile system for starting a lot of little seedlings in a short amount of time instead of direct sowing to get a jump on things.
