I'm not familiar with the Jonsered range, which I think may be sold under other brands as well? We have quite a few threads on Greenfields though, and it seems to me to be an excellent mower for simple straight-line mowing. If you are going to back and fill and manoeuvre around the rose gardens all day, you need something different of course, but more complicated machines with higher wear rates and more expensive parts are not the answer for simple jobs. On the other hand, in-laws are family, and they do seem to have given you the thing.
Good luck with finding a happy answer for everyone concerned.
