Welcome Linus.
Regarding magazines for modern equipment you really only have those aimed at the farming community. Farmers Weekly is probably the best known but its a bit to general for my taste, not enough on machinery.
The magazine I buy for the current and new machinery is Profi. See http://www.profi.com/EN_en I find it very informative and deatiled on modern day equipment. Some of the article eminate from Germany where the magazine was started but its all translated in to perfect English.
My local WH Smiths sells the magazine or you can get by subscription.
