Built Like a Tank – Great for Heavy Cutting Jobs!
I’ve been using the FXLM-312 for a little over a season now, and I have to say, Sicma knocked it out of the park with this flex wing mower. I run it behind my 90 HP tractor mainly for pasture maintenance and clearing overgrown hay fields. This mower handles thick grass, saplings, and uneven terrain without missing a beat. The flex wings follow ground contours really well, which helps avoid scalping and gives a consistent cut. It’s also quieter and smoother than I expected for something this heavy-duty. Maintenance has been minimal thanks to the heavy gearboxes and easy-access grease points. If you’re looking for a wide cut and true durability, this mower is worth every penny. I’ve used Land Pride and Bush Hog in the past, but this Sicma is easily on par with those—if not better in build quality. Highly recommend for anyone managing serious acreage.
