Hi Styvo
welcome here we try to have fun most of the time.
I guess if you asked most of us why we do it some would also say not sure but I like doing it and others would say just because I can.
As you have discovered the Tornado bodies are a bit on the average side and fall to bits. Also incase you hadn't noticed the crank is longer so you can fit it on a Talon base easily or if you want to fit it on a standard Victa base it needs to be spaced up 20mm, no big deal.
Anyway, welcome here and have fun, and as you have noticed, most of us can only use one mower at a time
