For $900 (including the NEEDED wheel kit), this product doesn't perform as expected. Assembly was intuitive, and went smoothly. Seems to be built very well, and is sturdy, but....... I needed to wait for my plots to dry out after a very wet spring, so I am now just getting a chance to use this. I set up the disc's at maximum angle for maximum effectiveness, started with no additional weight. Immediately the harrow had a bad tendency to want to "walk", even at very low speed (1-2 mph). So I kept adding weight (up to ~150lbs), and changing the angle of the disc's. only running the disc's strait eliminated the walking. I even tried shifting the cement blocks and rock weights to see if there was an odd balance issue......no deal. Very annoying to say the least. And this is why I purchased this particular implement, it was wide, so as to avoid any high center of gravity issues with some of the other disc harrows out on the market.

No instruction manual???

I was able to assemble by myself fairly quickly, but it is a heavy piece of equipment. Tested it this past weekend on food plots that we have not turned over in 2 years and it worked great. 1st pass around I ran the disc straight just to cut top soil, then moved to 2nd pitch angle and made 1 pass, then set to 3rd pitch and it really turned up the soil. I only had 2 4x8x16 solid blocks for weight. It does take some time to do an acre plot but it works great.

Works good just gotta go slow and add a lot of weight
