I have the identical 6' version under the "Howse Import" brand. It's also sold under Northern Tools and Homier brands.
The wheels and tires are junk. If you hit a medium sized dirt clod or crawfish chimney, the caster wheel spindles break off at the weld.
I took the blades off and sharpened them, and while balancing them, I couldn't balance 1 of the 3. It soon became apparent why. The heavy end of the bad blade was around 1/16" thicker than the rest! I had to grind on it for 30 minutes to balance it decently.
I actually like the housing, the pulleys, belt adjustment, and the beefy looking spindles and bearings. I do not like the hitch, as it puts the mower too close to the tractor tires. If you're not careful, you can hit the tractor tires with the mower wheels when lifting it.
The unit is noisy. The gearbox ratio is on the low side, so blade tip speed is too low. That necessitates running your tractor wide open to get an acceptable cut. A 5' Bush Hog finish mower can be run at a lower RPM, and still cuts fine. Overall, the cut quality rates a "D" in my book.
I have replaced the RFM with a 6' Bush Hog Squealer(which mows grass better!), and as soon as I can weld the spindles back on 2 of the wheels, I'm selling it... cheap and with caveats.
I do not recommend this unit unless you are handy with tools and welding, and like to tinker.
