Fits my 40 hp Massey Ferguson 1840m perfectly. Very easy to operate and hydraulics are so smooth. Does a great job mowing grass and also works great on brush. All of the components of the mower are heavy duty and well made. The only negative thing I have to say is it does not hook up to my Cat 1 quick hitch. Other than that I would definitely recommend.

Great customer service. Will buy again from this company. did some extensive online shopping for a fail mower and its the cheapest found so far and luckily it was on sale at that time. lt was built tough made with high quality materials. Thanks MECHMAXX.

Works ok with a 1025R. Power is great. Would like a bigger weight tractor. We.have used it to trim trails and edges of the yard. Putting fluid in tires would help also.

I purchased the MechMaxx 48" Standard 3 Point Offset Flail Ditch Bank Mower, 25-50HP, VAM48, and an extra set of Flail Hammers. I am extremely happy with this attachment and the entire purchase experience. The mower is well designed and constructed and matches well to my tractor. I used it to mow a large wooded area covered with various types of grass, ground cover, and brush. The hydraulic offset and bank feature was a big plus in being able to work around trees and uneven ground. While MechMaxx offers free shipping on this item, I opted for the optional premium freight service and received the and mower via appointment with FEDEX liftgate service. Shipping time was quick with excellent email status updates. The shipping crated is a sturdy angle iron frame which does a good job of protecting the mower. The included assembly instructions were also very good, and I was able to assemble the mower solo by mounting the 3 point arch frame to my tractor and then assembling the rest of the mower from there. This is the second piece of equipment I have purchased from MechMaxx and I would definitely recommend this mower.

I was very impressed with the quality. It was much heavier steel and quality than I expected. Mower cuts great, just take the time to dial in the top link to getting it cutting perfect.

Mower does great, performs as expected. Couple of nuts and bolts missing from shipment, but replacement was quick and easy, no hassel from customerservice.

Very pleased so far. About 10hrs of use. Install was straight forward. One hydraulic fitting was loose and some scratches through shipping. Overall, very good only regret is not going with the 65! Well built and solid performance with nice finish. Happy with this purchase!

I must say, I am very impressed with the fit, finish, and quality of this implement, so far it's sailed through everything I've thrown at it, and always leaves a nice, clean looking finished cut. Highly recommend!

I purchased this {68'' PTO Driven Flail Mower 3 Point 30-60hp , NAM68 }
I have a brush hog that I tow with my Kingquad but not happy with the wind rows it threw. The flail mower seemed much more efficient and they were right. It mulches everything I run over including rocks. I made a skid adjustment to help with the rocks. When I was done with about 9 acres of about 2' mixed grasses and wild roses I thought I should sharpen the hammers Would have been tough working under the three-point so removed it and used my shop hoist to hold the mower vertical. the hammers looked bad but to my surprise a 4 1/2 " grinder sharpened them quickly and did not remove much material at all. I have some heavier brush to deal with next year so will give it the true test. I recommend ordering the spare belts and hammers although I have no need for them yet. I did hit all the hammer bolts with an air impact and got a few 1/2 & 1/4 turns out of a few hammer bolts. Tested after the 9 acres and found NONE loose... Ohh, I'm using a JD 3038 E / No problem.

This NAM68 is a BEAST!!!! BUY 1! DONT HESITATE!!!! Everything ive cut with it has been a masterpiece. Grass. Brush piles. Small trees. Small stumps. Ive shaved some high spot down on my property and leveled it for easier mowing next time. Its a mower, stump grinder, brush grinder all in 1. Its SOOOOOO much quieter than a bush hog style mower. No vibrating. BEYOND happy with my purchase. Once i used it i sold every other cutter i own. My tractor is 40 hp and its perfect for it. Ive been mowing thru our small forest between the trees and kids can now ride thru the trees on bikes or any other little rides to enjoy the property. I was surprised how good the belt drive works. I figured i would smoke them or have to tighten them constantly. Nope. They hold so good ive killed the engine 2 times but no slippage. I would push every person thinking about buying 1 to go ahead and dont look back. You will not regret it!!!!

They handled my request quickly and professionally. Couldn't ask for better service. The openable back cover also helps with airflow when you're cutting really thick, dry grass.

Using the hydraulic hoses is straightforward. They were the perfect length for my tractor's rear remotes.

Finally, a mower that doesn't require constant belt adjustments. The integrated tensioner really does prolong the machine's life.

This 63-inch beast is exactly what I needed for my back pastures. It covers so much ground in a single pass, saving me hours of seat time.

The self-cleaning scraper is a genius addition. No more stopping every 30 minutes to clean the roller.

The mulching is amazing shreds into fine pieces that disappear quickly.

The rear cover opening is a lifesaver. Cleaning and blade changes are super easy.
