Manufactured well. Prompt response from Net Attachments when I had questions. Worked really well to restore my 1,500 ft. gravel driveway. Easy to assemble and switch from aggressive to smoothing. Would have given 5 stars but chain harrow likes to fall off the back chains unless you have the three point hitch angle perfect, but even if perfect any uneven terrain makes them want to pop off the chains. Had to do a home remedy to stop that from happening. 4.5 stars.
