The MechMaxx NAM72H flail mower is built for efficient large-area cutting while still offering the precision needed for edge work and tight spaces. With a 72-inch working width and integrated hydraulic side shift, this mower allows you to easily maintain fence lines, tree rows, ditches, and perimeter areas without constantly repositioning your tractor.
Designed for tractors in the 45–85 HP range, the NAM72H uses a heavy-duty hammer flail system to cut through dense grass, weeds, and overgrowth while producing a clean, mulched finish.

What Our Customers Say
Built like a tank
It handles my F-250 like it's nothing. 12,000 lb capacity gives me confidence with the heavy trucks that come through my shop. Installation was smooth and the build quality is commercial grade all the way. Best investment I've made for my garage.
Best investment for my garage
I've always worried about dust, moisture, and dings in my garage. This solved all of that. The airflow system keeps everything clean and dry inside, Easy to set up and worth every dollar.
Easiest garage upgrade I've ever done
I was nervous about installing flooring myself but these tiles just snap together no glue, no tools, no prep work. Had my whole two-car garage done in one afternoon. It looks incredible and cleans up with just a hose. Should've done this years ago.
Worth every penny
Bought the MEC10 with the Honda GX390 engine to dig trenches and do some grading on my property. It's compact enough to fit through my backyard gate but still digs down to almost 66 inches. The Honda engine fires right up every time. Saved me thousands vs. hiring out.
