Works very well as a regular flail mower or in offset mode. I have about 2 miles of fenceline to mow and this mower makes it easy to get close without hitting a post with ny tractor. Be sure to torque every bolt on the mower when you get it. Even the ones that are pre-assembled. Add oil and grease everything up and it should run like a top. I have about 10 hours on it so far and it has held up well. For the price, this is so far a great value.

This product works as it should. The cut quality is excellent. In the future due to the build quality of this equipment I will most definitely be looking at additional products from this manufacturer.

Mower was very easy to assemble. Came in with nice packaging. I had very tall brush on my land about 3-4 feet tall. It was able to mow it down and cut it up into small pieces. It does a great job. PTO was easily able to be cut to fit my tractor. Works great. Highly recommend this product and will buy more products from Mechmaxx in future. See results in pictures.

This mower is a beast. I've used it clear massive weeds, 2-inch brush trees and even tried it on cattails. The thing I like about this mower is that it can grind everything down to a half inch and mulches the sticks and branches, so there is no "cleaning up".

I use this mower in my apple orchard, and it's perfect for the job. The hydraulic side shift lets me get close to the tree rows without damaging them. Clean cut every time, and it runs smooth with my 50hp tractor.

I use this flail mower on my cattle pastures, and it's been fantastic. My 50hp tractor runs it with no issues. It chews through tall weeds and leaves the field looking neat.

It's been a solid experience so far. One feature that stands out is its ability to handle small branches and debris. I often pile up twigs and small branches, and this mower shreds them efficiently, which is impressive for a mower in this class.

Thanks to this flail mower I have a very nice yard! What a huge transition from a hayfield to a nice lawn. But I forgot about the weeds in the backyard next to the house. Well, at least everything else looks good.
