Yes. But in most cases ... in fact in almost all cases, you will get permission to use the model shape as long as you do not profit from it.

Nobody is going to say NO Rick, but they will ask you to plug them for the use of their work. And if you do, I suggest you abide by their request.

Don't take it the wrong way. Your right there is a little BS in all of this but companies need to protect the rights of their work from someone coming along and doing whatever they please with it. It's not Knife Edge you want to hear from on this subject ... it's more like Great Planes. They are the ones that have interest in protection of their models.

And Woops ... I'm only talking about the FTZ version of the mower. No other one, I know there are others. Ricks model is based on the FTZ version.
