Really happy with the NAM60. Very well built. Handles grass, brush, and saplings with ease. Perfect for maintaining trails and fields.

The NAM60 Flail Mower mowed down my 5 acre field of 3-4 ft weeds with ease! The biggest headache had nothing to do with the mower but with the quick hitch. I thought quick hitches would be standard ... nope! If buying a quick hitch, verify the width and category hooks. Surprisingly, there are quick hitches that fit category 1 tractors but the hooks are category 3 so you must buy adapters. My quick hitch was 30 inches wide (too big) so I bought an "Adjustable Lift Pin", "Quick Hitch Bushing Kit", and "Quick Hitch Adapter" for the top link. The quick hitch allowed me enough clearance so I didn't need to cut the PTO shaft. I got it all figured out and then let "Angry Bear" roar!

Good customer service. Takes a couple of days to get responses to questions about shipping timeline and updates. It also took a bit longer to leave their warehouse than I expected. I think 3 weeks. The unit its self is built like a tank. It mulches brush about 3" in diameter if you can get it to feed into the mower correctly and not just fold it over. Some times it takes a few passes for larger stuff. Still faster and less effort than a chainsaw. Grass and small brush is no problem for it. I am operating the mower with a JD 4300 30hp tractor. It does a nice job. very smooth and quiet unit. I have had a small leak on the unit since new. Drive shaft housing, belt side seal leak. It is a very slow leak, so not a deal breaker. I figure it is a compromised seal from the factory. I would buy this unit again.

Overall excellent product. Very well built at an excellent price. One drawback was difficulty in getting it hooked up, as the manual doesn’t provide much instruction on assembling the suspension bracket.

I ordered the Mech Maxx NAM 60 to take place of a 5 foot brush hog that I was not happy with cutting a 5 acre field. These are built very and make a great finished product, dispersing the mulchings evenly, and not spitting out a big clump, but be aware it is not John Deere imatch compatible, which isn’t a dealbreaker with me. Moving forward this will be the only tool that I use when cutting pastures or tall grass.

I was very skeptical to purchase this brand as I did not see too much information online. I was nervous about the brand and shipping hoping this wasn't a scam I was pleasantly surprised. I have now used the NAM60 4 times and it works flawlessly! It is a extremely well built machine and surpassed my expectations. The shipping was phenomenal and you can see the first picture showing the condition it arrived in, well done! I've used it on my John deer 2320 on overgrown fields and 1" diameter saplings. Two additional pictures show the before and after on the same field. Buy with confidence.

The safety chains on the front are a lifesaver The safety chains on the front are a lifesaver. I hit a few hidden rocks, and the chains kept the debris from flying everywhere. Very well-designed.

The PTO shaft snapped right into place. The belt drive is smooth, and you can tell the power transfer is efficient. No slipping even in the dense stuff.

This thing is a beast. I hooked it up to my 45 HP tractor and it cleared a field of waist-high weeds like it was nothing. The forged hammers really make a difference compared to standard blades.

Happy with how it performs This mower is a game changer for my property. It clears rough areas while leaving a neat finish that looks professional. The flail blades chop up grass and weeds into fine mulch, which saves me cleanup time.

This mower is built tough and feels like it will last for years. Attaching it to my 3-point hitch was simple, and the PTO drive runs smoothly every time. I use it on uneven terrain, and it still manages to deliver a nice, even finish.
